If there is no power to the dryer at all, homeowners should first check that the power cable is securely plugged in and that the outlet is working. A voltmeter, multimeter or a plug tester can be used to check the outlet.
If the outlet does not function, homeowners can check the home circuit breaker or fuse box to ensure the circuit supplying the outlet has not tripped. If the outlet is good and there is no visible damage to the power cord, a blown thermal fuse in the dryer itself may be the culprit.
If there is power to the unit but a drying cycle will not start, they can check the panel door to ensure it is closed firmly and that the latch is clicking into place. The dryer does not start if the latch isn't engage. They also can check the door switch in the upper right of the front panel for wear or damage. If the switch is not engaging or functioning properly, the dryer acts as if the door is open.
Homeowners need to ensure that the dryer selection knob is not in the "Wrinkle Guard" position when trying to start a cycle because it does not start from this position. If the dryer has power but still refuses to start, a bad start switch may be the problem. The start switch can be checked with a multimeter, ohmmeter or continuity checker.
