Reznor 201961 Limit
The Reznor 201961 Limit Switch is a high-temperature safety control engineered for specific gas-fired unit heaters, including Reznor UDAP, UDAS, UBX, and UBZ series. This OEM Reznor replacement part features a factory-calibrated trip point of 275°F (135°C) to prevent heat exchanger damage and combustion failures. This SPST auto reset limit is identified by its distinct green dot, ensuring technicians can quickly verify the thermal rating during a field diagnostic. When the internal temperature exceeds the safety threshold, the switch opens the circuit to the gas valve; the auto reset functionality restores continuity once the system cools to safe operating levels, reducing nuisance service calls while maintaining strict safety protocols.
Designed for easy field installation, the Reznor 201961 provides precise thermal protection for commercial and industrial heating applications. Proper integration into the control string is essential for unit heaters like the Reznor UDBS or UDBP models. Replacing a fouled or cycling limit with this 275-degree limit switch ensures the equipment operates within its engineered thermal envelope, protecting the primary heat exchanger from stress and premature fatigue. Always verify the specified temperature footprint and terminal configuration before mounting to ensure exact compatibility with the furnace control board.
Key Benefits- Automatic Thermal Reset: Restores system operation automatically once temperatures drop safely below the 275°F threshold.
- OEM Precision: Genuine Nortek Global HVAC component ensures exact fitment and performance for Reznor heating systems.
- High-Visibility Identification: Color-coded with a green dot for rapid technical verification of the 275-degree trip rating.
- Critical Safety Protection: Open-on-rise SPST contact arrangement prevents overheating and potential fires by interrupting the combustion circuit.
What does the green dot on the Reznor 201961 signify?
The green dot is an industry-standard marking for this specific Reznor limit, indicating a fixed trip temperature of 275°F. Using a switch with an incorrect color code can lead to delayed tripping or nuisance shut-offs.
Is the Reznor 201961 compatible with all Reznor unit heaters?
It is specifically designed for select models such as UDAP, UDAS, UBX, and UBZ. Always cross-reference your heater's full model and serial number with the manufacturer's parts list to confirm this is the correct high limit.
Can I bypass this limit for testing purposes?
Bypassing a safety limit is only permissible for short-term diagnostic testing by a qualified technician. Operating the unit with a jumped limit is extremely hazardous and can cause permanent heat exchanger failure or fire.
