Model # PFTL91105
The basic problem is when I insert the key the treadmill turns on. The display lights up and it looks like it is ready to go. If i start it up the motor runs, the belt engages for about 3 seconds then it restarts. By restart i mean the screens go blank (but do not turn) then the info reappears and i can start it up again and the same thing happens.
if i turn it on, but do NOT start it, the same thing happens, it beeps, the screen goes blank and then it comes back on.
Here's what i have done so far:
1) Entered calibration mode. Interestingly it runs fine in calibration mode. the belt turns on and stays on. it was running a bit fast so i did take off the cover and calibrate it
2) while i had the cover off i checked all the connections and confirmed that the red light blinks steadily while the motor is engaged. I think this confirms communication between the MCB and the console?
I appreciate any help or insight. I'm very handy and am comfortable with fixing things on m own, but i don't know what i need to fix in this case!
