Precor Error Code 63 High RPM

Jan 27, 2022

Applies to Chrono(Spinner Chrono Power Bike)

 

Issue symptoms

RPM is or has been detected as too high. The RPM is measured from one of the three, time-varying AC(Alternating Current) phases from the generator (pin 3). May be a temporary condition due to some rider pedaling modalities.

Troubleshooting steps

1. Use the RPM service test to measure the real-time RPM while pedaling. Pedaling one rotation per second will read 60 RPM. The test should read approximately 9 VAC(Voltage in an Alternating Current Circuit) at 60 RPM.
2. When pedaling, the RPM should vary based on the speed being pedaled. If always high or low, the likely cause is the LPCA(Lower Printed Circuit Assembly Board) is not sensing the AC variations.
3. If it appears random or different than normal, examine the Generator Output voltage. It may be varying excessively if one phase is not functioning.
4. Replace the LPCA. If conditions persist, replace the generator.
