Customer Questions and Answers for Broken Belt Switch (Dryer) by Whirlpool

This broken belt switch monitors drive belt tension and cuts power to the motor if the belt snaps or slips. Replacing a faulty switch restores proper start/run operation and maintains the dryer's built-in safety shutoff. What it does:

• Monitors belt tension through the idler mechanism
• Opens the motor circuit if the belt is broken or loses tension
• Helps prevent the motor from running when the drum isn't turning
• Failure symptoms include: dryer won't start, stops soon after pressing Start, or no motor sound while controls have power

• Includes 1 broken belt switch

• Disconnect power; turn off gas supply for gas models
• Access the switch near the belt/idler area; many models require removing the front panel and drum
• Note wire locations; move connectors to the new switch and secure in the original orientation
• Inspect belt and idler for wear; ensure correct belt routing/tension before reassembly
