Product Overview
The 240006292 is an electric heat limit switch with a manual reset, sold by RetroAire for use in electric heat applications. It ships as a standalone switch, ready to wire into the existing heat limit circuit.
The switch monitors electric heat element temperature and opens the circuit if it senses an over-temperature condition, cutting power to the heating element. Because it uses a manual reset, the switch stays open after a trip until a technician physically presses the reset button, rather than re-closing on its own once the unit cools. That forces a technician to diagnose the cause of the over-temperature event before the equipment runs again.
When replacing this part, disconnect power to the unit before removing the old switch, and verify wiring and mounting against the equipment's installation sheet. Have a qualified technician confirm proper operation, including a manual reset test, before returning the unit to service.
