How to Test the Start Switch

The start switch is located inside the control console. Remove the screws on the side or lower front (they may be hidden under trim pieces that will have to be removed first). Place a towel on top of the dryer to protect the finish. Tilt the control console forward onto the towel and remove the rear panel.

Caution: Please read our safety information before attempting any testing, maintenance or repairs.

Before testing the start switch, unplug the clothes dryer or shut off the power at the fuse box or breaker panel to avoid an electrical shock hazard.

Locate the start switch, it will have two or three wires connected to it. Label the wires and connections so that you can properly reconnect them later. The wires are connected with slip on connectors. Firmly pull the connectors off of the terminals (do not pull on the wire itself). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If either is corroded they should be cleaned or replaced.

Use a continuity tester or multitester to test for continuity. Set the multitester to the ohms setting X1. For a two wire switch, touch one probe to each terminal. You should get a reading of infinity. With the probes still in place, press and hold the start switch, the reading should change to zero.

For a three wire switch, touch one probe to the terminal labeled NC (or CT1) and touch the other probe to the terminal labeled CO (or R1). You should get a reading of infinity. With the probes still in place, press and hold the start switch, the reading should change to zero.

If the switch fails either test, it should be replaced.
