Problem with a treadmill: it occasionally works and stops

I have a "Power Run 3.6 easy" treadmill from ENERGETICS, which gives me error E2. I checked the speed sensor and it is OK. Can you suggest me any test that I can do to understand what does it depend on?
Good morning,
About your request for error E2 I recommend making some checks and then see what to do. Unplug the machine and:
1. Try turning by hand the motor to see if it has a fluid and frictionless movement
2. If it does, try to test the treadmill with only the motor connected (disconnecting the drive belt)
3. Does the running belt seem to be worn out? It could generate motor resistance, perhaps with some abnormal friction
4. Is the error displayed immediately (just when the machine is switched on) or is it displayed after a while?
Customer response
I did the tests you suggested, but the treadmill continues to give the E2 error.
Error E2 is displayed at power up after several seconds scanned by a beep.
I add that for 2 times, at different times since the E2 was presented, the machine at power-on has worked normally. So sometimes it goes, sometimes it does not go.
The speed sensor works.
What further tests can I do?
If every now and then the motor goes and occasionally runs and then doesn’t, I would recommend sending the motor for testing.
In fact, this type of defect may depend on the motor and could also cause damage to the board, so it’s better to check the motor before further damage is made to the machine.

Problem: Nordick Track treadmill jumps out, solved with 110V motor replacement with 180V motor

Let's summarize the experience of this customer
The customer sent us as his board and engine to be tested at the laboratory. The lab found a defect, which was leap current
Lab finds KO motor short, controller to be repaired.
After some time, the customer receives the card and the original engine (new) Nordick Track.
After some time, the customer contacts us again saying that he has another problem, this is his description of the problem: «I tried it for 25 minutes after which I turned off everything, I checked the fuse that was close to the plug and it was blown, I reactivated it but as soon as I start the treadmill, the engine starts to turn “jumpy”, I also tried without the engine connected. Your technician told me that even without the engine the light should blink but instead it remains off”
After a few days the controller came back to the lab, and we find out that the board is damaged again on the power output part, probably due to incorrect maintenance or "load" side issues. The controller is still repaired and the customer is required to pay a very reduced fee for the repair.
The lab confirmed that they replaced the power part of the card. It is the part which gets damaged in case of "load" problems, such as wrong maintenance, old tape (too much friction), etc.
Even after this the customer still complains about the treadmill malfunction. It starts, you can walk on it for 5 seconds and then it stops again. Without anyone (unloaded) works fined, but with a person of about 60/70 Kg stops
A replacement board is then sent to the customer, which accepts both 180v motors and 110V motors. The treadmill works fine a few weeks, after that it still notices problems with the card.
The new board (with original engine) causes the same problem. The customer agrees to try the replacement engine 180V.
After that we received the new message from the customer: “Good morning Luca, I tried with the engine that you sent me. It looks like it's okay now. I used it for about 40 minutes and it did not stop. I wanted to ask you if it is normal that after the 40 mins training the engine gets quite hot. Thank you.”
Afterwards we sent the customer instruction on how to adjust the main running belt and the drive belt.
He wrote us back: “Sorry for the delay, now it looks like it's okay”

Problem after replacing the treadmill motor

I replaced the treadmill motor with a new one, and connected it. Now I have a problem, the treadmill without any command starts at maximum speed. Faston connectors are properly connected (red + black –) if I put them opposite, treadmill reverses direction and stops immediately after that. Please help.
To reverse the direction of the treadmill, it is enough to reverse the red and black cables, unfortunately the fact that it starts immediately at maximum speed means the control board is short-circuiting.
So, you may want to check if it can be repaired or not.

Modify icon brand treadmill (Nordick Track, Proform, Weslo), with larger engine (180V)

Example treadmill modification using a “3 HP Mega Motor” motor type and an Eway compatible controller
Here are some advantages:
- the use of a bigger engine (10 cm in diameter compared to 8 of the original engine), allows better heat dissipation and reduces engine overheating even under harsh conditions
- The use of 180V motor technology allows a reduction in the current (A) resulting in further reduction of the risk of overheating and consumption. It is also more suitable for use in Europe (where the mains current has a voltage of 220 ~ 240VAC)
- The most powerful engine is suitable for longer use
A similar result can be obtained by applying a change to the original Icon Controller board, as follows

I cannot measure the belt of the treadmill

I guess I cannot measure the belt because it's sliced so I can do it??
If it is broken, cut it with a cutter, pull it out and then measure it. If you do not succeed, you have to pass a string along the entire length of the path the belt should have, from there you can find the length. You should also check (by removing the lateral end caps) the position of the adjustment nuts, to understand if it is better to replace with a little longer or a little shorter belt than the original.
The list of belts we have available is on the internet and you can find it at the following link. They cover almost all makers and models of treadmills, tailor made belts for special models are also available.

How to Repair Bike Computers

You can do the adaptation by splicing the cables and connecting them directly if the contacts do not exactly match those of the original computer.
Speed sensor (Sensore n. giri in the pic) is always a single-pin 2-pin cable that differs from the others. Two pins are almost always enough for the bike speed sensors.
The double connectors (sensori cavi pulsazioni) are 2 cables, usually one of the two is white, they are handpulse sensors. They might be 3 or 4 wires. Each pulse need at least one cable + one which may be in common.
Note that if the bike has jack type connectors (headphones), these are interchangeable with those of the example computer above, but if you see a connector made up of a single long cable strip, this is not compatible and you need a different computer (bike “ergometer” computer with automatic tension adjustment).

Error E1, E2, E3, L5 and LS on treadmill

My Prorun K30 treadmill has problems with the motor, it starts but stops shortly after, and L5 error appears on display. I would need technical assistance or any information about any check I can do to understand what’s the problem.
Error L5 is like error E1. It would better read as LS (low speed). Usually you can fix it by replacing the speed sensor or the motor controller.
In fact, for the E1 and the similar errors (some models call it E2, E3 (rare), low speed, or LS) you have to distinguish
- If the treadmill runs for a few seconds and then stops showing E1, low speed or similar -> 99% is the sensor that does not work anymore. BUY SPEED SENSOR (you can find them on
- If it works for some time (minutes) and then stops showing E1, it is often the controller that goes into protection (may be worth checking the running belt if old or not lubricated, and also check problems with the motor such as electric leaks.) Buy motor, belt or test your engine. (see
- if it clicks and then stops, the controller is short or the motor is short. Test them. (see
- if it does not move at all, 99% the controller is faulty. Replace the controller. (see

Adjusting the treadmill belt if it does not keep the position

 I ask you kindly to explain what should I do on the treadmill that presents this little problem:
- the belt slowly moved all in the left part (seen from above) and is therefore no longer "centered"; what adjustments should I take, should I adjust on the front or on the rear roller?
The front roller must be perfectly aligned and should never be touched for adjustments.
To adjust the belt, you can use only one of the nuts on the rear roller, turning it clockwise or counterclockwise depending on the effect it seeks (if you remove the two endcaps, it will be easier for you to see what happens).
When adjusting the treadmill should be going at around 2/3 km / h unloaded (nobody on the belt) and you can start by turning the nut (1 full turn / if no effect repeat with max another turn), so that the belt returns in the central direction. Once the center is reached, the belt will tend to "go to the other side", so you should turn maybe 1/4 or 1/2 turn in the opposite direction to the initial adjustment to settle.
If it seems good now, you can gradually increase the speed, checking that at higher speeds your belt do not tend to move (in which case you repeat the operation again, with ever smaller and more accurate adjustments) until you reach the max speed.
1) If at first it is very "off-centered" you can initially push it manually (pointing your feet when the belt is turning at low speed) to make it go a bit in the middle. This is to prevent the belt from ending up on the rim of the footrest and ruining, crawling on.
2) If you need to adjust very frequently, check the leveling of the feet and the floor itself. Also check if the running belt is not under-tightened (avoiding, however, to over-tighten). If even tapered and well tensioned, the belt tends to move around, check your own way of walking / running because probably you don’t run in the middle, or you push with one foot more than the other and this can be a good opportunity to fix a little for a better training.
---------- Running belt tension instructions (if necessary) -------------

You can self-test and adjust the correct belt tension. Turn both adjustment knob to release tension from the running belt until it slips on the roller when loaded. Then tighten it slowly up to the best coupling. Be careful that if the running belt is old (> 4 years old) and very tighten, it is better to replace it with a new low friction belt.
To set the correct tension of the belt, remove the motor cover, start the treadmill (should rotate at low speed), climb onto the belt, hold the handrails and try to lock the belt.
Check whether the engine continues to rotate but the belt stays it means something is slipping (the belt, the drive belt or the pulley).
Tighten the belt and until the belt - roller – drive belt - motor coupling is perfect, do not over tension, because it only adds load to the treadmill, resulting in early wear on the transmission system and board / engine parts.

A problem with the treadmill, which seems to be due to the motor but turns out to be caused by the belt

A problem with the treadmill, which seems to be due to the motor but turns out to be caused by the belt
Below is a summary of a long email exchange with a customer who had problems that ultimately turned out to be caused by the belt. After testing and changing a lot of components, the customer finally decided to follow the advice ...
J.G. Customer “I have a problem with my TC 470 Domyos treadmill. It happens that after a few minutes of using it at a speed of about 4 km / h the treadmill stops despite the display working. If I come off the belt it starts to turn and if I go back it stops. Until a few days ago it did it once and then worked, but tonight it continues to block. I took off the engine compartment cover and noticed that when it stops is not the belt sliding or anything else but the engine stops. I thought it might be a problem with brushes and then I unplugged the engine from the treadmill but did not open it to avoid further damage. I wanted to know what you could advise me and, if you think it might be the engine, what to do. The engine type is ICON 2.8hp 130VDC / 2089 watts.”
We wrote to the customer: “First, do not use the treadmill in these conditions because of the risk of further damage. The problem depends on the engine, which has probably developed some internal electrical dispersion, this makes it possible to activate the board protection. In turn, damage to the motor can be endemic or depends on the treadmill used or poorly maintained. Could you send me a photo of the engine?”
Customer J.G. “Thanks for the prompt reply, definitely before using it I will have to fix the problem. Anyway I tried to lubricate the belt, but nothing. However, the motor is identical to that of the 2.8 hp 130 vdc Icon that you sell used at 90 euros and you have the photo on your site, or alternatively the new one is compatible with 130 euros. Anyway tonight I'll take a picture and I'll send it to you”.
[We tried to convince the customer to replace the belt, but after some email exchange the customer decided to buy a used engine and not the belt]
 [10 days later ...]
J.G customer: “Hi Luca, unfortunately even with the motor you gave me today, the problem remained, even if it took a minute before it stopped, your motor stops after 15 seconds. With the tester I could not measure the absorption because in my opinion it is only for AC. Anyway the engine for the two times I tried was cool. Now tell me what you can do.”
Our answer: “Do you confirm that it stops after the same time even if there is no one on the treadmill?”
Customer J.G. “Unloaded does not stop but this was also true for the original engine, it's clear I did not go for so much time”
Our reply: “we can send you to test the old engine to see if it can still be used, while for the rest, if the problem emerges always when treadmill is loaded, you need to replace the belt”
Customer J.G. “Why do you say that I probably have to replace the belt? Maybe because it makes too much friction on the board? But it looks new!!! So your suggestion is, I test my motor, I send you back and pay the difference of the new belt, right?
Our answer: “I confirm the offer is that. To control the belt’s quality and friction, you should check how many A absorbs the engine when you are on the treadmill. However, since the components involved are only board, motor, belt, and deck, the probability of the belt is very high, especially if the belt is older than 3 years because it loses its properties.”
[... the client then decides to send his card and his engine for testing]
J.G customer: “Hi Luca, this weekend I did not have to do anything with the treadmill. Anyway I decided to disassemble engine and board and let you have them for testing.
[after 10 more days we get the results of the lab]
We wrote the customer: “Hi John, I have good news from the lab, which tells me that "new engine, older one and board, all three work fine"
[after a few days the old engine, board and belt are delivered to the customer]
Customer J.G. “Works!!!!! My treadmill started working again, thank you for your help.”

Replacing the controller for MC 2100

We have MC2100 Icon Controller updated to the latest available technology. The new design of the circuit is improved for greater reliability and uses 1/5 of standby energy compared to older models. The new versions of the MC 2100 series controllers have only 2 AC input terminals. Replacing a previous series controller (MC2000) that has 4 AC input terminals requires a simple wiring change.
1. White AC faston cable Connects to AC NEUT (LG3)
2. Short blue cable goes from AC switch to AC HOT (LG2)
3. Black AC cable connects to the remaining blue wire from the motor. A short extension of the cable must be removed to connect the black to it.
Depending on which controller you are replacing, you may need to change the connector and the supplied connectors. All other connectors (data and sensors) are the same.
Remember: the main reason why the treadmill motor controllers fail is because of lack of maintenance and lubrication of the running deck or because the running belt is too old and generates excessive friction. Protect your investment by checking and lubricating the tape every 40-60 hours of use.
This is the link of the new controller:

Modifying shunt resistance- mc2100 board astek treadmill weslo proform nordick track

In this video, we demonstrate how to modify the shunt resistance for calibration on high power motors with the Astek MC2100 controller (10cm diameter engines). It is necessary to use an electrical cable with a section 1-1.5 mm and connect it between the R6 pitch and the shunt resistance. The video shows the situation before the change, where adding a load on the motor causes the card's extra-protection to be activated.

The situation after the update is flawless.
Buy proform, weslo, nordick track spare parts at
Here are the steps of modification:

First step: original card, the R6 pitch is free

Second Step: We're getting the cable on R6

Third Step: The cable is welded on the R6 pitch and is also welded to the shunt resistance.
Step 4: Cut off the excess cable

MC-54 MC-70 MC-2000 MC-2100 Installation and calibration

With the treadmill disconnected from the current, connect all wires to the connectors as indicated. There are a total of 6 (MC54), 7 (MC70), 5 (MC2000), 10 or 12 (MC2100) terminals on the board. Keep all cables away from the white power resistor on the controller (for MC2000 and previous type cards). This resistance becomes very hot during use.
These steps are optional if the board has been repaired / upgraded.
Status 1. Press and hold the speed button + stop at the same time and do not touch any other key while you insert the safety key. This puts the treadmill in setup mode. The speed window will display the maximum speed of the treadmill. Release the buttons. Models manufactured before 1997 have an alternative sequence: press speed - and tilt +.
Status 2. Press the stop button once. The distance window will read % PWM speed signal. The speed window will display the actual speed of the treadmill.
Calibration of the tilt:
While the treadmill is in the state 1 press one of the two tilt buttons. If the gradient is controlled by the console, it will be calibrated automatically. Note: Some models do not have any inclination calibration.
Speed calibration:
WARNING, be on the footpaths of the treadmill or with your feet on the ground. Do not stay on the belt. The treadmill will reach the maximum speed.
Before proceeding, you must locate the speed control trimmer on the controller. It is all white or black with a white center, or blue with a white or yellow center. This is what should be set if speed is incorrect during calibration. The number in the distance window should reach zero.
When the button + speed key is pressed, this number will reach 85 very quickly and the belt will accelerate very quickly. I recommend that you press and release the speed key to increase the number more slowly.
If you reach the maximum speed (as shown in the speed window) before reaching 85, use a screwdriver to lower the speed control trimmer (counterclockwise). When you reach 85, the maximum speed will be displayed in the speed window. Turn the speed controller trimmer up or down to find the maximum speed of your treadmill. It does not have to be exact, but it is better if it is within +/- 3 km / h.
Very important:
When finished, press the speed button - and let the belt stop. Remove the safety key. Reinsert the safety key and try the treadmill. If all is ok, disconnect the current, reassemble the covers and restart.
To keep your board and motor in a working condition as long as possible, follow the directions on our blog.

Indoor Sports: benefits of treadmill

There are many contrasting opinions if it is best to run at home or outdoors. Outside, you can experience a beautiful panorama, beautiful weather, and the breeze of the wind. Undoubtedly, it is more pleasant to work outdoors, but there are also benefits of training indoors.
1. Race.. weather permitting
"A little rain has never hurt anyone" - but depending on where you live, weather conditions can be a huge problem for daily workouts. Snow or ice can cause accidents during training, and too much heat can lead to dehydration and fatigue. In some circumstances, even air pollution can be dangerous.
2. Security first
No matter the city where you live, going out alone can be dangerous. Most runners tend to get out early in the morning or late at night. And in the winter months, it’s light quite late in the morning and gets dark very early in the afternoon. Why risk the safety factor?
3. Take the necessary amount of water
Dehydration can become a serious problem, especially when doing sports outdoors without having a bit of water with you. Running with a bottle of water is not quite pleasant. Treadmill Benefit: Most standard treadmills come with cup holders.
4. Create your workout
A lot of times, you go out without mapping a path, or your smartphone has a low battery and you cannot use a running app to track progress. The advantage of the treadmill: Many treadmills have programs to help customize and create your own workouts.
5. Easier for joints
Though land can vary from place to place, it is certain: it is unpredictable what can be found outside. From smooth concrete, to sidewalks, to brick, to grass, to dirt. Some of these surfaces can strain your legs, especially the joints. Treadmill Benefit: The tool provides the right texture and cushioning system and helps the muscles and joints.
6. More heart rate control
Setting a target heart rate is the best way to achieve results, whether you want to work on fat burning or whether you want to have a cardiocirculatory training aimed at enhancing the heart-lung system, if you want to follow directions of a physician in rehabilitation. HRC programs on treadmills allow you to set a target frequency and the treadmill will change speed and gradient to keep you as close to the target as possible. The results? An increase of 24% of how many calories you burn in a workout and a strong reduction in the risk of overtaking with heartbeats or vice versa, keeps a rhythm too low and therefore irrelevant.
7. You arrive and leave home
Sometimes it is quite difficult to get out of bed in the morning, change and go out for a workout. Benefit from the treadmill: With a treadmill within arm’s reach, there are no more excuses!
