BASEMENT FLOODED. DRYER HAD ABOUT 3 INCHES OF WATER IN THE BOTTOM. NOW CONTROL PANEL WORKS AND ONLY A CLICK HAPPENS WHEN TRYING TO START DRYER. WOULD THE MOTOR MOST LIKELY BE THE FAILED PART SINCE IT WAS IN THE WATER?
Answer TB, You're on track, a water logged electric motor 279787 has little to no chance of starting or running, without a complete rebuild,so you'll need to replace the motor. You'll also want to check the belt switch W10411937 operation and circuit. and the igniter and radiant sensor on the burner assembly, they could be damaged by water as well.
When starting our dryer, the sensing light lights up, and we hear a click, but the dryer will not start. What could be the problem?
Answer Hello Brian,
You will want to check the thermal fuses and thermostats to ensure continuity. These would be the most likely cause for the failure. You have a thermal fuse on the blower and one at the heater. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
How can I be sure that the motor is bad? I've done the resistance measurements and they are a little low, (2 ohms rather than 2.3-3.6), but I expected them to be high if the motor had failed. I measured the resistance from P1-3 to P1-4 at 2.1 ohms, which makes sense to me given the wiring diagram. However, the tech sheet states that if the resistance is in the range of 1 to 6 ohms, "replace the machine control electronics." Should I replace the motor or the control board? If I have to replace both I'll just buy a new dryer!
Answer Hello Jim,
In light of the statement, " if the resistance is in the range of 1 to 6 ohms, replace the machine control", I would replace the electronic control 280087. The tech. sheet will be right 98% of the time.
We have a Kenmore gas dryer and have just changed the thermal fuse but are still having problems. When we try to put the dryer on it hums and doesn't turn if we move the drum it turns on and after a little while it will go off. Could it be the motor if not any suggestions as to what it could be?
Answer Hello Judee,
You have a bad winding in the motor 279787. This will cause it not to start and it will make it run hot if you help it. The overload on the side of the motor will kick off and turn the motor off when enough temperature is accumulated.
It would be a good idea to check for exhaust duct restrictions as excessive heat being held in the unit will cause premature electronic component failure. This would explain the thermal fuse failure and the motor failure. If the issue is not addressed, you will continue having dryer problems........even if you get a different dryer!
