GAS DRYER Won't HEAT
My Maytag gas dryer (Model MGD5570TQ) turns on OK but after a while, the flame goes out and does not come back on. I can see the "glow plug" lighting up / cycling - but no flame. I cleaned out the vent and completely replaced the ducting to the outside. If I re-start the dryer after waiting a while, it heats up again, but then goes out and continually tries to re-ignite. Any idea on what the problem is?

These driers will do that when the lint builds up like concrete on the inside of the air ducts. Halfway doing it will not work. You need to totally tear it down and scrape out and wash all of the parts except the motor, which you vacuum out. You can go to YouTube to see videos on how to take it apart, but do a very good job or it will fail again quickly. I would get a new belt and change it while you have it apart and get some white lithium grease and grease any bearings you find. You need to clean out a drier every two years, at least, according to the manual. You just unplug the wires from the sensors and remove ductwork that they are attached on and clean the entire thing with soap and water. Make sure you go all through the dryer and get all parts like the blower fan and housing, vacuum out motor well and clean exhaust. Mark all wires you unplug so you know where they go. This is an easier job than you would think. My sister does hers at least once a year since she has five children and the dryer gets a lot of use. Make sure to clean around all of the sensors, too.

Dr. Tom,

I tore the dryer apart and cleaned every piece, but got the same results. It came on for a while, went out, and tried to cycle on again - with no luck. I tested 4 things with an ohmmeter after removing one side. One looked like a fuse and it had continuity. Two other pieces had 2 connectors - and they showed continuity. The last one had 4 connectors - so I tested the opposing pairs. One pair was fine, but the other was open. Could this be my problem?

Thanks, Nick

You will have to look at the wiring diagram. It very well could be bad if the other two are hi-limit contacts. There should be a wiring diagram on the dryer somewhere and there should be one that matches in one of the manuals.
