Description
The Carrier 338096-709 is an OEM replacement limit switch designed to protect furnaces and heating systems from dangerous overtemperature conditions. Identified by the L215-20F designation, this high-limit switch monitors heat exchanger temperatures and interrupts burner operation when unsafe temperature thresholds are reached, preventing equipment damage and potential safety hazards.
How It Works
The limit switch continuously monitors the air temperature within the furnace plenum or heat exchanger area. When temperatures rise beyond the rated set point, the switch opens the control circuit, shutting down the burner. Once the system cools to within the rated differential, the switch automatically resets, restoring normal operation. This automatic protection cycle ensures your heating system runs safely without manual intervention.
