Lennox 36K14 Limit Switch L99H008 Dual Refrigerant Compatibility: Specifically calibrated

Dual Refrigerant Compatibility: Specifically calibrated for R22 and R407C

this assembly utilizes automatic ball checks to prevent accidental media discharge in the event of glass breakage

non-electric solution that eliminates the risk of sensor failure during power loss

it is standard practice to mount these relays in a position that allows easy access to the bias adjustment and prevents moisture accumulation in the ports

Replacing the entire pilot burner assembly is often more reliable than trying to clean a fouled orifice or a degraded mounting bracket

Lennox 36K14 Limit Switch L99H008 Dual Refrigerant Compatibility: Specifically calibratedThe Lennox 36K14 Limit Switch is a high limit safety component engineered for precision temperature monitoring in residential and commercial furnaces. This OEM replacement part operates as an auxiliary limit switch designed with a 150F open and 140F close thermal profile. When the heat exchanger air temperature exceeds the 150 degree threshold, the switch opens the circuit to the gas valve, preventing overheating and potential component failure. The
