Walt for Model Number mdg7400aww I recently purchased a timer from your company for my dryer. I spoke to someone on Sunday. The first timer the dial would not turn to zero and shut off dryer. I received a replacement today and tried it out, and it still won't turn the dial and shut off. The dryer is heating up and running. The purchase order is 3732460
Answer Walt, based on the model and serial number on APP order #3732460, you have a "series" 20 machine. The correct timer for that model and serial number is WP33002803 the tag on the timer should contain the number 6 3720660 (MPN). If the new timer will not advance, then the issue is in the dryness display board assembly 33002905, or there is a broken white (neutral) wire in the harness or no neutral at the outlet. Read More...
