Precor Error Code 36 Excessive AC Average Input Current

Jan 14, 2022

Applies to TRM800-14/18 treadmills, 120VAC only

Issue symptoms:

This error will occur if the Overload Slowdown (Error 38) continues to detect high current and has limited the treadmill speed below 5 MPH (8 KPH). The most likely cause of this is a worn deck and belt. It is possible that this error could be caused by a combination of a worn deck/belt and the Treadmill dynamic brake resistor being stuck ON. Low line voltage can cause Error 36; however, this usually causes an Error 16, so check for that error in the log. If Error 36 occurs when the treadmill is fairly new and the facility has not had other treadmills plugged in previously, it is possible that the wiring to the outlet is not of sufficient gauge to conduct the current required.

If the speed drops below 5 MPH or 8 KPH and the overload condition is still present, an Error 36 will be displayed, and the treadmill will be temporarily out of service. It will slow to a stop but will recover from the error.

Troubleshooting steps:

1. Check the belt rating (120 VAC only) and current draw of the treadmill. Replace the belt and deck, if necessary.
2. Monitor the minimum line voltage as follows:
   1. With the Treadmill at the Welcome banner.
   2. With a runner at 6MPH.
   3. With the TRM at the Welcome banner and a runner at 6 MPH on an adjoining treadmill.
   4. Check for fluctuations of greater than 15% between steps 2a and 2b, or fluctuations of 5V or more when running on the adjoining TRM.
3. If either of the conditions in step 2d exist and the error has been occurring frequently and/or on multiple units, request an evaluation of the facility distribution wiring.
