Why Does My Pro-Form Crosswalk 390 Control Screen Not Work?

SOURCE: my control board does not work...buttons cant be

Remove the console from the treadmill and remove the back
remove and replace the ribbon cables that run from the keypads to the control board (they are flat plastic strips that push into the board).
remove and replace all the connections on the console
reattach the console and calibrate by doing the following:
1. With the key off press the speed + and stop buttons at the same time and hold
2. place the key on and release the buttons
3. press the stop key once
4. press the speed up til it reaches 85
5. if your max speed is 10 mph then it should read about 9.8-10.2

If the keys will not work then the console is bad and would need replaced.

if the motor controller card is the model MC_60 you should change D4015L diodes and SCR's S4015L but if MC_2100 you should change the MOSFET IRFP250N

SOURCE: Pro-Form Crosswalk 395 - Incline goes up and down with no tread movement. Calibration doesn't work - only on display.

test the main board, with the output voltage from board for input voltage motor. If there are NOT voltage the board is faulty.replace see the block diagram, how the main boad control about 80% of the machine motion.
God bless you
