Nick for Model Number GTDX180ed2ww Why would the timer resistor stop the dryer from heating? the timer advances, but the heat element won't work I opened up the dryer and tested all the thermostats and the heating element. The only thing that failed the ohm test was the timer resistor!?
Answer Nick, The resistor is in line with the heater and thermostats and could cause this issue of no heat but check the resistance of the resistor for 4.5K ohms of resistance. If the resistance is not correct then replace the resistor. 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 . Read More...
