There could be several reasons why your treadmill is stopping after running for only a few seconds. Here are a few things you can check:
Power source: Make sure your treadmill is properly plugged in and that the power outlet is working.
Safety key: Ensure that the safety key is in place and fully inserted into the console. If the safety key is not properly inserted, the treadmill will not function.
Motor: If the motor is not working properly, the treadmill may stop after running for only a few seconds. Check the motor by turning the treadmill on and listening for any unusual noises.
Belt: A loose or worn-out belt can cause the treadmill to stop running. Check the belt tension and replace the belt if necessary.
Control board: If the control board is malfunctioning, it can cause the treadmill to stop running. Check the control board for any signs of damage or wear.
If you are unable to diagnose the issue, it may be best to contact a professional to come and take a look at your treadmill.
If it stops but you can still hear the motor running then I would check the belt tension. The force of you running could be causing the belt to stop but no the drive.
the motor could be going bad or the control board.if you are able to remove the drive belt off the motor and then run it. this will determine the motor or board from the walking belt or other items being bad.the motor should not be too hot to the touch
Precor Error Code 21
Error Code: 21
Manufacturer: Precor
Model: All Models
Error Description:
Error 21, Too many Consecutive Power Requests- The error 21 observes a treadmill's power bit reading when the treadmill was operating at speeds above 1 mph. Power bits indicate the relative time that the motor controller drive circuit is turned on. Power bits is an indication of the amount of power the load is demanding from the motor controller. Error 21 indicates that at a speed greater than 1 mph, an excessive amount of power is being demanded from the motor controller.
Possible Reason:
A badly worn deck and/or running belt can cause the error to appear when the unit is in use.
Badly worn drive motor brushes may not be making proper contact with the drive motor commutator causing the error to occur when the unit is in use. The unit may also slow down or become sluggish when the load or speed is increased.
A jumper may be required on the lower PCA if installed into a 120 VAC (Version 2) treadmill.
A leaky or shorted drive motor filter capacitor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
A leaky or shorted drive motor inductor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
The high power demand is caused by a shorted or de-magnetized drive motor.
Recommended Action:
Determine the amount of AC input current being drawn by the unit under no load and loaded conditions using a clamp on AC ammeter. The current displayed can be used to determine the condition of the deck and/or running belt. These same readings should be taken on a like unit, in good operating condition with a know good deck and running belt. The readings from the unit in good operationg condition can be used as the benchmark. Compare readings and replace* the deck and/or running belt if necessary. *Some units have a reversible deck. Be sure if the deck is being flipped or replaced, a new belt is installed on the new deck surface.*
Inspect and repalce both drive motor brushes if necessary.
Inspect the lower PCA (if unit is 120 VAC/ Version 2) for jumper. If jumper is not installed, error typically appears between 7 mph & 8 mph. Install jumper if necessary. CAUTION - DO NOT install jumper if unit is 240 VAC. Installing the jumper on a 240 VAC unit will casue the lower PCA to fail.
Measure the AC input current without a load using a clamp on AC ammeter. Electrically isolate the filter capacitor from the drive motor circuit. The drive motor leads need be kept intact so the drive motor will operate with the filter capacitor removed from the circuit. Re-measure the no load AC input. If the AC input current is significantly lower, replace the filter capacitor.

Precor Error Code 20
Error Code: 20
Manufacturer: Precor
Model: All Models
Error Description:
Error 20, Too many Maximum Power Requests in 1 Second - The error 20 observes a treadmill's power bit reading when the treadmill was operating at speeds of 1 mph or less. Power bits indicate the relative time that the motor controller drive circuit is turned on. Power bits is an indication of the amount of power the load is demanding from the motor controller. Error 20 indicates that at a speed of 1 mile per hour or less, an excessive amount of power is being demanded from the motor controller for an excessive length of time.
Possible Reason:
Starting the running belt under a very heavy load can cause the error 20 to appear.
The user (especially a heavier user) is standing on the running belt as they start the belt into motion.
A badly worn deck and/or running belt can cause the error to appear when the user steps onto the belt.
Badly worn drive motor brushes may not be making proper contact with the drive motor commutator causing the error to occur when the user steps onto the running belt. The unit may also slow down or become sluggish when the user steps onto the running belt.
A leaky or shorted drive motor filter capacitor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
A leaky or shorted drive motor inductor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
The high power demand is caused by a shorted or de-magnetized drive motor.
Recommended Action:
Instruct the user to straddle the running belt while starting the treadmill at a low speed, such as 1mph or less, and then step onto the running belt.

1) LUbe the deck belt, the lack of lube produce Shut down, by enough friction between deck vs deck belt 2) Lube the rollers bearing very well 3) Measure the input voltage motor, if there are the motor need repair 4) Measure the output voltage board, for input voltage motor, if there are Not the board is faulty. 5) Run the software calibration, for diagnose, and troubleshooting. God bless you
A treadmill will shut down from to much friction which is due to high motor current because the walkbelt and deck are not properly lubricated. I would recommend replacing the motor controller,walkbelt,deck and applying .5 oz of lubricant on the deck every 3-6 months or 100 hours of use. This will extend your treadmill's life many years.
