Reznor 174812 End Switch
This genuine Reznor 174812 End Switch is a critical safety and operational component designed for precise cycle regulation in Reznor gas-fired unit heaters and duct furnaces. Engineered to monitor mechanical movement within the burner or damper assembly, this switch provides the essential electrical feedback required to confirm the completion of a specific cycle, such as the full opening of a damper, before the system initiates the next stage of operation. By ensuring accurate sequencing, the Reznor 174812 prevents common field issues like overheating or premature component failure. This replacement heating system part is a direct factory substitute for part number 47031100 and is compatible with a wide range of Reznor equipment, including unit sizes from 100 through 1200 across various models. Designed for professional HVAC controls and electrical maintenance, this unit heater safety switch features a robust construction to withstand the thermal stress and high-cycle demands typical of commercial and industrial heating environments.
Key Benefits for Technicians- Precise Cycle Verification: Provides accurate end-of-travel signaling to the control board, ensuring safe burner ignition sequencing.
- Broad Model Compatibility: Replaces PN 174812 in Reznor unit models ranging from 100 to 1200, reducing the need for multiple truck stock variants.
- Professional-Grade Reliability: Built to endure rigorous industrial cycles, reducing nuisance service calls caused by switch failure or signal drift.
- Direct OEM Replacement: Ensures exact fitment and terminal alignment with existing wiring harnesses for faster installations.
Which Reznor models use the 174812 end switch?
This switch is compatible with a broad spectrum of Reznor unit sizes, specifically fits models 100, 125, 150, 175, 200, 225, 250, 300, 400, 500, 600, 800, 1000, 1200, and 1600. Always verify your specific serial number for exact fitment.
What is the primary function of an end switch in a unit heater?
The end switch acts as a sequence validator. It typically confirms that a damper or mechanical arm has reached its terminal position, closing an electrical circuit that allows the gas valve or inducer motor to proceed safely.
Can I use a universal switch in place of the Reznor 174812?
While universal switches may look similar, utilizing the OEM Reznor 174812 ensures the correct electrical rating and physical mounting tolerances necessary to maintain the unit’s safety certification and operational efficiency.
