Precor C966i The unit turns off at random intervals. When reset it comes back on then shuts off a few minutes later. Error log is empty so not an error with software.

Problem: The incline goes up on its own (e.g., you can run the treadmill and, while using it, the incline just goes up on its own..and I'm not in 'random mode').

What I've done (per the Precor 9.23 service manual):
- initiated the "initialization program"
- "calibrated the lift motor"
- I checked ohm reading on the potentiometer per the Precor manaual. From the board (JK3), the readings are fine (red-to-black = 10, red-to-white plus white-to-black = 10. When I read them from potentiometer itself (the other end of JK3, on the incline motor), the readings are off.
