This Lennox 42J05 limit switch monitors supply air or plenum temperature and opens or closes the circuit at a 130-170F range to protect the furnace or air handler from overheating. It automatically resets once the temperature drops back within range, restoring normal operation without manual intervention.
This is a genuine Lennox replacement part. Confirm the part number against your equipment's parts list before ordering.
