I am working on a Maytag microwave model number mmv5208ws-1. To start with it was blowing fuses, which was caused by the high voltage capacitor.
Once it got that fixed it now runs and heats but it will not heat at all for exactly one minute. The board will not send voltage to the transformer until it runs for exactly one minute (never 61 seconds or 59 seconds). Once one minute is up it will heat normal and if it is paused it will continue to heat it only has the delay if it is restarted.
I am guessing itís the smart board but it just seems so odd it almost seems like it is some kind of setting that is set wrong (just because this delay is so uniform (accurate).
