I have replaced my MCB, this was suggested to be my problem from issues I was having. Incline at max height we held the stop speed up buttons till two beeps then pressed the incline button it lowered then raised back to max and stopped we then pressed the speed button and belt went to max speed, hit speed button again belt came to a stop we then pressed the stop button and removed the key. powered back up screen comes on we press start screen pops up in manual for very short time then goes back to logo screen then asks again to press start, goes to manual mode you can get belt to move for a second then quits and incline does not do anything. It just keeps repeating this process. Can you offer some suggestions?
