Customer Questions and Answers for Limit Switch by Whirlpool

This limit switch monitors a set condition and opens or closes its contacts when that limit is reached. Replacing a failed switch restores proper safety cutoff and consistent operation of the appliance's heating or movement system. What it does:

• Senses a limit condition at its mounting point (such as temperature or travel/position, depending on model)
• Changes state at a defined threshold to protect components and wiring
• Interrupts power to heat or motor circuits, or signals a control to respond
• Common failure signs: no heat or shuts down early, runs continuously, won't start, or intermittent operation

• 1 limit switch

• Disconnect power to the appliance before servicing
• Note wire positions; transfer connectors one at a time or take a photo for reference
• Reinstall in the original orientation so the actuator or sensing surface contacts the correct area
• Address root causes (blocked airflow, binding mechanisms, shorted components) to prevent repeat failures
