Treadmill Error E1 on Strengthmaster Treadmills

Buy all the treadmill spare parts you need at cheap prices and great quality

Treadmill Error Code – E1
This Error Code may appear under 3 different situations:

• The “Start” button is pushed and the E1 error code is displayed immediately.
• The “Start” button is pushed, the display counts for 3 seconds, the DC Motor begins to run and then stop after 6 seconds, when the E1 error code is displayed.
• The “Start” button is pushed, the display count for 6 seconds, and then the E1 error code appears. The belt does not move in this situation.

Treadmill Error E1

After you determine which of these scenarios is occurring, please follow the instructions below to correct the problem.

If the E1 error code shows immediately it is likely a wiring connection problem. Check the connector at the back of the display, in the handlebars and at the bottom of the right side support post. Make sure that the connectors are turned the right way, that none of the pins are bent and that they are firmly pressed together. If this does not sole the problem you may have a problem with a wiring harness. Check to see if the harness was damaged during assembly by visibly inspecting the harness where the handlebars and the support post are connected during assembly and where the support post is inserted into the base. If there are signs of damage, you can isolate the mid-section of wiring harness and test to see if this is the problem through removing the display from the handlebars and attaching it directly to the end of the wiring harness coming out of the right side of the base. If the display now works properly, replace the damaged wiring harness.

If this does not resolve the problem, remove the bottom hood cover and replace the wiring harness from the controller board to the base.

If the E1 error occurs after the belt starts to move for several seconds, the error code means that the system is not picking up the speed of the motor. This pickup comes from a magnet mounted on the front roller pulley and a speed sensor, or a problem with the magnet. To resolve this problem, follow these steps:

A.    Check the connection between the speed sensor and the controller board. This connection will be sealed with hot glue to keep it from loosening. Make sure that the connection is secure without removing the hot glue.

B.    Make sure that the magnet is properly installed on the front pulley. If you cannot located the magnet on the pulley order a new magnet.

C. Replace the magnet and/or sensor
If this does not solve the problem, this is likely caused by a defective motor (too much current need from the motor causes the board to enter protection mode and stop the treadmill belt)

If the E1 error after the display count the workout time for 6 seconds but the belt never begins, the error code means that the DC Motor Controller is likely defective and needs to be replaced. The problem could also be associated with a defective motor.


  1. sensor is ok and magnate already ok carbon ok treadmill not run show error e1 please help me

  2. first check if motor turns smoothly, you can connect a 12VDC battery to m+/m- cables (usually black and red) of motor. If it turns, the problem is on the motor controller and you have to replace it.
    You can find at below link: motor controllers

  3. My tredmill. Shows E01. On screen and don't run.. Please help me..

    1. Hi, does it start and then stop? or doesn't start at all?
      First scenario (start & then stops) may be sensor, that's quite cheap, you can find it on
      If doesn't start at all, first double check cables connections, but it's likely to be a controller problem which is more expensive, you can check above website or contact people there to ask for price.

  4. Tunturi T40 treadmill - Runs without issue on its own. Once I start to exercise, the unit stops with E1 error anywhere between 10-50 sec, or on rare occasion goes 10-15 min before stopping. The Error LED flashes during this time before going solid. The magnet is in place, the speed sensor gap is good. all connections are tight, and belt is lubricated.

    1. Does it run well on its own, even if you increase speed up to the maximum?

  5. Yes, can achieve full speed without issue. It is only when the machine is loaded (ie someone walking) that the the Error LED starts to flash

    1. can you try to start the treadmill at low speed? And then make some pressure with your hands or with a cloth on the motor flywheel, to simulate load. If you can replicate the same problem, then the problem is likely to be in the motor. Maybe it has some electric leakage inside.
      If you can't replicate the problem, then it is likely to be in the running belt. You can get one low friction belt here:
