If your clothes dryer doesn’t run, perform the following diagnostics to determine the problem:

1) Be sure it is plugged in and turned on. If necessary, check the receptacle it’s plugged into for power, using a working lamp, appliance, or voltage tester. (Be aware that most electric dryers don’t plug into standard 120-volt receptacles; they operate on 240 volts.) Make sure the door is closed completely, the timer is advanced to the proper position, and the correct cycle is selected.

2) If the receptacle is dead, check the circuit breaker or fuse that serves that circuit.

3) Unplug the dryer and check the power cord and the terminal block. If necessary, replace the cord.

4) Open the door and check the door switch. Press and release it; it should click each time. If it doesn’t, it’s probably broken. Remove the switch, test it, and replace it if needed. 

5) If the dryer still doesn’t work, a thermal fuse or other electrical or electronic part may be faulty. The thermal fuse, found in the back cover panel, can stop working if the dryer overheats. Call an appliance service person if you suspect an electrical part may be malfunctioning.
