Customer Questions and Answers for Thermal Limiter (89°C) by Whirlpool

This thermal limiter (89°C) is a one-time, temperature-sensitive safety device that opens the circuit if internal temperatures rise too high. Replacing a failed limiter helps protect the appliance from overheating and can restore normal operation. What it does:

• Monitors temperature in the airflow/heating path and opens around 89°C to interrupt power when overheating occurs
• Helps protect wiring, controls, and heater components from thermal damage
• A blown/open limiter can cause: appliance won't start, no heat, or stops mid-cycle
• Often indicates an underlying overheating issue that should be corrected

• 1 thermal limiter

• Disconnect power (and gas supply if applicable) and allow the unit to cool before servicing
• Access the limiter per the service information; note wire positions and transfer leads one at a time
• Replace only with the correct rated limiter; never bypass this safety device
• After installation, clear airflow restrictions and verify proper venting and heater/thermostat operation
