Full Answer

A missing or bent plunger may be the reason a clothes dryer fails to turn on. The plunger is located on the dryer door and should be replaced if necessary. If the plunger appears okay, another possibility is that the door switch is damaged, either from slamming the door or regular wear and tear. Checking the condition of this switch requires disassembling the top cabinet panel.

A blown thermal fuse can cause a dryer to malfunction as well. This problem can be identified with a continuity tester or multimeter. If the test does not produce a continuity reading, it is important not to simply replace the fuse because the blown fuse is a sign of a bigger problem, such as a clogged vent or broken thermostat that requires fixing before the fuse is replaced. A continuity test should also be run on the radiant sensor if the unit is a gas dryer. The sensor requires replacement if the test fails.
