We have a front load Whirlpool Duet dryer, model number GEW9250PW1. After about 4-5 loads, the dryer panel will not power on, no lights, no beeps - nothing. The light on the inside comes on when the door is opened. If I take the top off and unplug all of the connections from the board on the left side of the dryer and plug them right back in (of course with the power disconnected), the dryer will work for another 4-5 loads. Can someone give me some advice on where the problem might be?
