The L215-20F High Limit Control Switch is a vital safety component designed for HVAC systems and forced-air furnaces. Functioning as a thermal safeguard, this disc-style limit switch monitors the air temperature within the heat exchanger or plenum. If the internal temperature exceeds the calibrated safety limit, the switch automatically breaks the electrical circuit to shut down the heating element or burner, preventing equipment damage and ensuring home safety. This replacement part is ideal for repairing furnaces that are cycling improperly, overheating, or failing to initiate the heating cycle. Engineered for durability and precise temperature sensing, it provides reliable performance in residential and commercial heating applications.
