Error 35 - Excessive Ac Input Current / Instantaneous; Error 36 - Excessive Ac Input Current/ Circuit Breaker Trip Prevention - Precor TRM 885.v2 Service Manual

Possible Remedies
Verify that the connector is properly seated in the Motor Controller MTH jack
1. Check the belt rating and current draw of the treadmill – replace the deck and belt as
necessary
2. Check the resistance across the motor thermal switch connector. If it is greater than 10Ω,
replace the motor
3. Verify the Motor Controller is working correctly by substituting a known good controller.

Error 35 - Excessive AC Input Current / Instantaneous

MCL – Green
ASL – Yellow Solid
Description
The Control Module monitors the AC input current, and if there is an instantaneous extremely
high pulse in excess of 65A, the control module will shut down and log an Error 35.
Possible Causes
1. Although this error is designed to detect and protect against a high pulse of current, the most
likely cause of this error being logged is a hardware failure in the Control Module.
Possible Remedies
1. Cycle power to the Control Module; if the error is persistent, replace the Control Module.

3.

Error 36 - Excessive AC Input Current/ Circuit Breaker Trip Prevention

MCL – Green
ASL – Yellow Solid
Description
The Control Module monitors the AC input current. If the AC input current reaches a value
slightly over 20 amps RMS (averaged over 2.5 sec.) and maintains this current for a period of
time, the drive motor system will shut down and an error 36 will be logged.
Possible Causes
1. Bad belt and deck
2. Shared neutral/wiring undersized
3. Low AC line voltage
4. DB resistor stuck ON
