Amana Dryer Won't Dry
« on: February 06, 2014, 12:33:57 AM »
Looking to repair a Amana dryer, model NED5240TQ0. Was told by the previous owners that they had a flood and the dryer was in a few inches of water. This was months ago and the inside is completely dry now. Everything seems to work fine except it won't heat. Tested the element, thermostat, fuse, etc for continuity - all are OK. Motor seems to be ok. Like I said, it works fine, just doesn't heat. Anything else to test at this point? Could it be the timer? It advances fine and shuts off when it should.

Hi,

There is a switch on the motor that has to close in order for the dryer to heat. The switch is part of the motor and can not be replaced separately. Your model dryer uses motor part # 279827

  On this dryer, if timer advances, then the problem is not the motor switch. Does timer advance when timer is set to auto-dry cycle? If so, problem is either hi-limit thermostat, thermal cutoff, operating thermostat or timer BK to R contact. Check BK to R continuity with dryer unplugged and timer on heat cycle.

Timer is NOT advancing when set to auto-dry. Unit was in a flood a few months ago and I'm going to try taking the motor out later and checking out the switch. Hoping the water from the flood just caused some corrosion on the connection that can be brushed off and that the entire motor won't have to be replaced.

  You said the timer advanced normally. If it advances in timed dry, then the motor switch is working. What was the resistance reading across the heater terminals? Did you check heater terminals to ground?

  Here is your wiring diagram showing current path for timer motor in timed heat cycle. As you can see, that path is through one of the motor switches. Same switch that completes heat circuit. If that switch is bad, the timer will not advance.

Always seems to be the last thing I check, do you have both legs of the power? If you only have one leg it will run and the timer will advance, but no heat.... Seem to have a lot of one leg trips with the old breakers up here. :)

  Timer motor on this model is 240vac. Timer can't advance at all with only one leg of power.
