I have an over range GE microwave. Everything is working fine except the recirculating vents and surface lights. They won’t work by themselves. I mean when I press VENT button, the display is on with right modes (BOOST/HIGH/MEDIUM/LOW) even though it isn’t actually running, same thing to the LIGHT SURFACE . But once the microwave is running, I can turn them up and they work normally. I think it would be something wrong with the board. Looking for any tips and advices.
