Whirlpool WP3977456 OEM Dryer Push-to-Start Switch

The Dryer Push-to-Start Switch starts the dryer when you press and release the button. To access this part, you'll need to remove the back top panel of the dryer with a Phillips-head screwdriver and disconnect the old switch from the wiring harness. Replacing this part will require basic hand tools, some disassembly of the dryer and novice repair experience. You must unplug the dryer or shut off the house circuit breaker for the appliance before installing this part.
