Precor Error Code 42 Lift Position Out of Range

Jan 16, 2022

Applies to All machines with a Lift Motor Issue symptoms The software on the lower PCA(Printed Circuit Assembly) expects the A/D(analog to digital converter) value from the lift potentiometer is within a certain range, low to high. If the A/D value goes outside this range, an Error 42 will be displayed. The most likely cause of this error is the motor moving further than it should or jamming...

Precor Error Code E4 Incomplete Initialization

Jan 16, 2022

Applies to 9.23, 9.27, TRM211, and TRM200-14 treadmills Description This error is shown in the console TIME window indicating an incomplete upper PCA(Printed Circuit Assembly) to lower PCA initialization has occurred. When the E4 error occurs, all drive motor and lift motor motion stops and the display is blank except for the error display. Troubleshooting steps Run the initialization ...

Precor Error Code ERR EEPROM Problem

Jan 16, 2022

Applies to 9.23, 9.27, TRM211, and TRM200-14 treadmills Issue symptoms This error is shown in the console TIME window when the EEPROM is damaged or unable to retrieve or store data. When the Err error occurs, all drive motor and lift motor motion stops and the display is blank except for the error display. When this error occurs consistently, it indicates an upper PCA(Printed Circuit ...

Precor Error Code LS Speed Sensor Signal Missing

Jan 16, 2022

Applies to 9.23, 9.27, TRM211, and TRM200-14 treadmills Issue symptoms This error is shown in the console TIME window when the drive motor speed signal is not received from the speed sensor for eight (8) consecutive seconds. When the LS error occurs, the drive motor and lift motor motion stops and the display is blank except for the error display. The treadmill uses a reed switch and two ...

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 ...

Precor Error Code 35 Excessive AC Input Current Spike

Jan 14, 2022

Applies to TRM800-14/18 treadmills Issue symptoms Error 35: This error monitors the instantaneous input current to the treadmill. If the input current spikes above 65 amps, an Error 35 will be displayed. The most likely cause of this error will be a catastrophic failure of the MC(Motor Contoller, Motor Controller Unit) Troubleshooting steps Recycle power to the treadmill. If Error 35 ...
