Reznor 106847 Limit Switch
The Reznor 106847 Limit Switch is a critical safety component designed for precise thermal management in Reznor HVAC equipment, specifically compatible with waste oil heaters like the RA and RAD models (110, 140, 235, and 500). As an L160-40F limit switch, it operates on a fixed temperature differential, opening at 160°F to prevent heat exchanger damage and auto-resetting when temperatures drop to 40°F. This SPDT high limit control is engineered for high-demand industrial environments, featuring a robust roller plunger actuator and an adjustable bracket for secure mounting in tight plenum spaces. When you are troubleshooting a unit that is periodically cycling on its high limit, verifying the integrity of this OEM replacement part is essential to maintaining safe operating conditions and consistent airflow.
Key Benefits for Technicians:- Precise Thermal Protection: Engineered as a fail-safe to deactivate the burner at 160°F, protecting the heat exchanger from cracks and catastrophic failure.
- OEM Compatibility: Drops directly into Reznor RA and RAD series units, ensuring the electrical ratings and footprint match the original manufacturer specifications.
- Industrial-Grade Control: Built with a Single Pole Double Throw (SPDT) configuration and rated for 10A at 250VAC to handle heavy-duty switching loads.
- Simplified Installation: The included adjustable bracket allows for quick field positioning, reducing labor time during emergency service calls.
How do I know if my Reznor limit switch needs replacement?
If your heater is short-cycling or the control board indicates a limit trip (often 3 blinks on modern Reznor boards) despite adequate airflow and correct gas pressure, check the Reznor 106847 for continuity. A switch that remains open after the plenum has cooled below 40°F has failed and requires immediate replacement.
Can this switch be used in gas-fired garage heaters?
While primarily specified for Reznor waste oil heaters, compatibility depends on the specific L160-40F temperature requirements of your unit. Always verify your heater's manual specifically for part number 106847 to ensure a proper thermal match.
What causes a high limit switch to trip repeatedly?
Beyond a faulty switch, frequent tripping is usually caused by restricted airflow, such as a dirty blower wheel, clogged air filters, or undersized ducting that prevents heat from leaving the exchanger.
