Nathan for Model Number AED4475TQ1 Dryer will not heat in any setting but the timer seems to be running through the cycles fine. I checked continuity in both fuses, heating element, operating thermostat and high limit thermostat. All were good. I get 240v and 120v on both legs at the block. I'm suspecting the timer because that is all that's left. Is there a way to read for voltage that would verify that the timer is what is causing the no heat issue?
Answer Nathan, There are 2 components other than the thermostats which would cause the heating element not to work. First is the motor and second the timer. The best option is to disconnect the power to the unit and access the heating element. Disconnect one wire that is going to the heating element, preferably the one on the thermostat side. Plug the unit back up and using a multimeter you will want to turn the dryer on and test for 120 vac at the terminal on the heater where the wire was disconnected. What this will do is eliminate the heater element itself and the motor. If there is 120 vac at this point then you know the heater is good and the motor is good because the other 120 vac coming through the thermostats is the timer side of the circuit. If there is not 120 vac at that point then you will want to test the other terminal on the heater and check for 120 vac. If there is not 120 vac then the motor would be bad and if there is 120 vac then the heater would be the issue. If there is 120 vac at each point then the heater is faulty. Read More...
