Is the console bad on my treadmill if the light flickers rapidly and I am unable to program it at times?

I have a Pro-Form 500i treadmill model 831.29604.0. I checked all connections (they are okay). The console light flickers rapidly at all times. At times you can program the treadmill, but once it runs it's course, it cannot be reprogrammed. Will replacing the console solve this problem or is there more to it? Can you help me with this problem?

A wire harness connection between the motor controller and the console could cause the flickering and the programming problems. The first image below shows the wiring diagram for your treadmill. I recommend that you check the wire harness connection between the console and the motor controller. The second and third images show additional troubleshooting and technical information on this treadmill. A failed motor controller could also cause your problem. If you are able to use this technical information, you may be able to verify a console failure or determine a different cause for your problem.

If you need more help, resubmit your question with additional details.
