Lennox 83L76 Limit Switch Els PW 17895 Low Maintenance Internals: Permanently lubricatedFor service technicians addressing furnace short cycling or thermal cutout issues, the Lennox 83L76 Limit Switch serves as a direct fit OEM replacement part designed for high limit circuit protection. This 140 180F AUTO limit switch is engineered with a calibrated bimetal snap disc that opens at 180F to prevent heat exchanger damage and automatically resets at 140F once the plenum temperature stabilizes. As a critical furnace safety sensor, it
