FAQ

WP3977456 is the push-to-start switch. When you press the start button, this switch sends electrical current to the dryer motor to begin the cycle. If the switch fails, the dryer may not respond when you press Start even though the timer, door switch, and power supply appear normal.
This switch fits select clothes dryers and some laundry center models from Kenmore, Whirlpool, Maytag, Amana, Admiral, Crosley, Estate, Inglis, Kirkland, Magic Chef, Roper, KitchenAid, and Jenn-Air. Compatibility is model-specific, so the safest check is to match your dryer's full model number and confirm the part numbers WP3977456, 3977456, AP6009036, PS11742178, EAP11742178, or 898073.
Known cross-reference numbers for this dryer start switch include WP3977456, 3977456, AP6009036, PS11742178, EAP11742178, and 898073.
Typical symptoms include the dryer not starting when the button is pressed, the button feeling loose or not making contact, intermittent starting, or needing multiple presses to start a cycle. In some cases the dryer has power and the door is closed, but nothing happens when Start is pushed.
On many dryers, this is a moderate repair that usually takes about 15 to 30 minutes. Basic tools often include a screwdriver and, depending on the model, a nut driver. The switch is commonly accessed by removing part of the control console, disconnecting the wire terminals, and releasing the old switch from the panel before installing the replacement.
First unplug the dryer. Then verify the issue is not caused by a tripped breaker, a bad outlet, an open door switch, or a blown thermal fuse. If you have a multimeter, checking the start switch for continuity while the button is pressed can help confirm failure. Also inspect the wire terminals for heat damage or looseness before installing the new switch.
Start switches commonly fail from normal contact wear, repeated use over time, internal electrical arcing, or heat exposure inside the control area. In some cases, loose terminals or damaged wiring at the switch can create similar symptoms, so it is worth inspecting the connector and harness during the repair.
