How to test continuity on a switch?
Use your ohmmeter to test your switch for continuity. Begin by setting your ohmmeter to measure resistance at a scale of R x 1. If yours is a two-wire switch, touch each tester probe to each of the switch's terminals. You should receive a reading of infinity. While the probes are still touching the switch's terminals, press in on and hold the switch. The reading should change to zero.
What is a door switch?
A door switch is a simple on/off mechanism that prohibits the dryer from operating when the door is open. Dryer door switches are a little over an inch long. Many are white in color and all have metal prongs, called terminals, extending out from the body of the switch. Some door switches have only two metal prongs extending from the body, ...
How many terminals does a door switch have?
Some door switches have only two metal prongs extending from the body, while others have three. Those with three terminals will have a common (COM) terminal, a normally closed (N.C.) terminal, and a normally open (N.O.) terminal. Those switches with only two terminals will have either a common terminal and a normally open terminal, or a common terminal and a normally closed terminal. We are providing directions for testing a door switch with three terminals. If you are dealing with a door switch that has only two terminals, ignore the part of this test that does not apply to you.
