Anthony Hampton for Model Number dv422ewhdwr/aa My Samsung dryer quit heating. There are no error codes. I originally thought the Thermistor was bad because the original one was reading open - I've read it should be about 10k ohms. I ordered a new one and the new one reads open as well. I installed it and still no heat. I have checked the heating element and it reads about 10omh, the thermal fuse on the vent reads closed, the thermostat and thermal fuse on the heater assembly reads closed (less than 1ohm). Any help would be appreciated
Answer Anthony, There are 2 components other than the thermostats which would cause the heating element not to work. First is the motor and second the Control board. 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 vacs coming through the thermostats is the control board 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...
