Deborah for Model Number MDE7400AYW My dryer will not heat. Just had a repairman come by told me it was the timer...$249 to repair. I respectfully declined due to the age of the dryer. In researching the timer, I do not see where this is a fix for no heat. Can this possibly be the fix? He said he checked the thermostat, heating element and thermal fuse and they were all ok. If the timer could be the fix, which one do I need? Serial number is 20443387EE. Thank you!
Answer Deborah, Yes, the timer WP33002803 33002803 could be the problem. The timer heater circuit is routed through cam no. 5 in the timer (black to red wires) from the timer to the temp. switch and through the thermostats to the heater element. If the timer contact fails the dryer wouldn't heat. The correct timer for your dryer based on the model and serial number is WP33002803 Replacing the timer isn't that difficult, you may want to give it a try yourself. Read More...
