Customer Questions and Answers for Limit Switch by Whirlpool

This limit switch is a temperature safety device that opens the circuit if heat rises too high. Replacing a weak or failed switch restores proper overheat protection and can resolve nuisance shutdowns or no-heat conditions due to an open safety. What it does:

• Monitors temperature at its mounting location
• Opens the electrical circuit at a preset over-temperature to stop heating or operation
• Helps protect internal components and wiring from heat damage
• Common symptoms include: won't heat, shuts off during use, or no power after an overheat event

• 1 limit switch

• Disconnect power (and gas, if applicable) before servicing
• Access the switch, note wire positions, and transfer wires one at a time
• Mount the switch flat and firmly against the original sensing surface or bracket
• After replacement, check for root causes of overheating (blocked airflow, failed fan, dirty filters, shorted element)
