Shawn for Model Number mdg6700aww My gas dryer runs, but the heater will not turn on all the time. I've checked for lint blockage and it's all clear. Bad thermostat?
Answer Hello Shawn, The first suspect is the ignitor WP33002789. The only accurate way to test it is with a clamp on ampmeter. Clamp it onto one wire going to the ignitor and look for 3.2 to 3.6 amps. If it's low, replace the ignitor. If it shows in the correct range, you need to replace the coils on the gas valve 279834 or the gas valve WP35001190. Read More... Answered by AppliancePartsPros.com | Thursday, August 30, 2012
