Earl for Model Number MEDB850WQ0 I have a Maytag Bravos electric dryer, Model MEDB850WQ0. It began to get too hot in the lower temperature modes, then overheated and would not run. The Power button worked, but the dryer would not start even when pushing the Start button. Using your website and the Tech Sheet, I found that the Thermal Fuse, Exhaust Thermistor, and the Thermal Cut-off had no continuity. The heater element is in in good shape, and not shorted against the duct. I therefore ordered and replaced the following components: Thermal Fuse, Exhaust Thermistor, Thermal Cut-off, and Inlet Thermistor. My exhaust duct is clean, and air flow is very good. When I turned the dryer on to test it, it was blowing very hot air in the Air Fluff cycle, when no heat should be on at all. Can you please provide any additional troubleshooting help? Thanks!
Answer Hello Earl, since you have already checked the heater element and it is not grounded then check the heater relay on the main control board. Unplug dryer from the electrical outlet or turn off the dryer's circuit breaker and locate the heater relay on the main control board, it has black and red wires going to it, disconnect the wires and using a multimeter test for continuity. It should read as an open circuit, if closed then replace the main control board. Read More... Answered by AppliancePartsPros.com | Monday, July 1, 2019
