Reznor OEM Limit Switch — 106847 L160-40F
The Reznor 106847 is an OEM replacement L160-40F limit switch engineered to protect Reznor heating equipment from unsafe operating temperatures. Acting as a critical safety device, this limit switch monitors heat exchanger temperatures and interrupts the burner circuit when a high-temperature condition is detected, preventing equipment damage and potential hazards.
How It Works
The L160-40F designation defines the switch’s operating parameters: the switch opens (trips) at 160°F to shut down the burner, and resets automatically once the temperature drops by 40°F — restoring normal operation at approximately 120°F. This auto-reset functionality ensures the unit returns to service once safe temperatures are re-established without requiring manual intervention.
Key Features
