Question about Precor 9.23 Treadmill

1 Answer

Precor 9.23 Treadmill Inclines Randomly

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 manual. 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. - I have not seen any error codes

The incline on our Precor c964i is stuck in a high position (approx. 10% incline). Other than being on a high incline, the treadmill seems to be working fine.


Hi There,

Precor uses a pair of Triacs to drive the lift up and down. These triacs live on the lower board but are driven by the upper console commands via a serial link between the upper and lower. Most precor lift issues we see are related to the lower board but with Precor it could be an upper board or the CPU Chip that resides on the lower board or a failed Triac. Good Luck

Precor 927 stuck in incline position


How long have you let it run for after turning it back on ? Some treadmills have a re calibration test built in and will incline to the max and work its way down. During this time you should simply walk away and not touch anything as it trys to calibrate its self. If not i will need more information on it

Upon powering up my precor treadmill goes straight to the highest incline


hi,
Your treadmills motor controlling circuit have some problem. thats why you cant adjust its speed. its running at its high speed because its motor controlling IGBT become shorted. As these potion of your treadmill is a high voltage point, i will recommend you to consult the manufacturer for support.

Hi, my Precor 9.21 treadmil was working fine, however all of a sudden it became unblanced, i stop it to see what the problem was and then it dropped from about 3 inch, and now there is no power, would...


Unplug unit remove motor shroud take a look at incline motor frame assembly, by the sound of it maybe metal fatigue failure disengaging the incline motor itself and could have damage it. This would be my best guess if so contact Precor.
