Reznor 210761 Temp Control

The Reznor 210761 is a critical OEM replacement oil temperature control designed specifically for the pre-heater assembly in Reznor waste oil furnaces. For technicians troubleshooting a locked-out burner or inconsistent ignition, this 170F oil temp control ensures the fuel reaches the precise viscosity required for efficient atomization. Operating with a 15-degree differential, the switch closes to allow the heater to maintain a steady thermal profile, preventing the common issue of cold oil sludge clogging the nozzle or causing flame failure.

Built for the rigors of heavy-duty shop heating, this waste oil heater thermostat features integrated wire leads for a direct localized mount on the pre-heater block. Relying on an oil pre-heater temperature switch that meets exact engineer specifications is the only way to ensure the combustion head doesn't overheat or underperform. This component is essential for maintaining the heat exchanger's integrity and ensuring the unit heater cycles correctly during peak winter loads.

• Precise Thermal Regulation: Calibrated to 170°F to ensure waste oil is rendered at the correct viscosity for clean combustion.
• Optimized Differential: The 15°F differential prevents rapid cycling of the heating element, reducing wear on the Reznor HVAC control.
• Exact OEM Fitment: Designed for seamless integration with Reznor 210761 oil temperature control housings, eliminating the need for field modifications.
• Durable Wire Leads: High-temperature lead wires come pre-attached for a secure connection in the heat-intensive pre-heater environment.

• How do I know if the oil temp control has failed? If the furnace is in lockout and the oil feels cold to the touch despite having power, the 210761 switch likely has an open circuit.
• Is this compatible with all Reznor waste oil models? This part fits most flagship waste oil series (such as the RA or RAD models) using a 170F pre-heat setpoint. Always verify your specific model number.
• Can I use a higher temperature switch instead? No. Using a switch with a different setpoint can lead to carbonization of the oil or unsafe operating pressures within the pre-heater.
