Customer Questions and Answers for Thermal Cut-Off (Tml) by Whirlpool

This thermal cut-off (TML) is a temperature safety device that opens the circuit if overheating is detected, protecting components from heat damage. Replace a failed or tripped cut-off to restore safe, reliable operation.

• Monitors temperature at its mounting point and interrupts power at a preset limit
• Helps prevent overheating damage to components and wiring
• Typical symptoms include no power, shutting off during use, or no heat—depending on where it's installed
• Can be tested with a multimeter; an open (no continuity) reading indicates replacement is needed

• Disconnect power before servicing; some appliances (e.g., microwaves) can store dangerous high voltage—use proper discharge procedures
• Replace with the same type/rating and mount in the same location/orientation as the original
• Ensure solid contact with the sensing surface and clear airflow/venting to prevent repeat overheating
• Do not bypass thermal safety devices; verify proper operation after installation
