Reznor 197033 Rollout Switch

The Reznor 197033 Rollout Switch is a critical safety component designed for high-limit flame rollout detection in Reznor heater units. This manual reset rollout switch operates with a fixed temperature setpoint of 210 degrees Fahrenheit, providing essential circuit interruption if burner flames escape the combustion chamber. Engineered with a Single Pole Single Throw (SPST) configuration, this switch serves as a direct replacement for Therm-O-Disc 36TX16-6832. It is commonly utilized across Reznor’s line of unit heaters, including the Reznor UDAP and UDAS series. As a safety-critical HVAC replacement part, it ensures the system shuts down power to the gas valve if excessive heat is detected near the burner manifold. For field technicians, confirming the continuity and trip point of the Reznor 197033 is vital during annual maintenance to prevent heat exchanger damage or hazardous operating conditions.

• OEM Compatibility: Precision-engineered for a seamless fit in Reznor gas-fired unit heaters, ensuring factory-standard performance.
• Manual Reset Mechanism: Requires manual intervention after a trip, forcing a technician's inspection to identify the root cause of the rollout.
• Industrial Build Quality: Features a 1/2-inch bimetal disc for reliable thermal response and long-term durability in high-cycle environments.
• Direct Cross-Reference: Identical to industry-standard Part #36TX16-6832 for simplified inventory management and cross-compatibility.

What causes the Reznor 197033 to trip?
A trip typically indicates a flame rollout caused by a cracked heat exchanger, soot buildup, or improper venting pressure. Always inspect the heat exchanger before resetting.

Is the 197033 compatible with models outside of Reznor?
While designed for Reznor units, its SPST 210°F manual reset specifications allow it to replace any part cross-referenced to Therm-O-Disc 36TX16-6832.

Can I bypass this switch for testing?
Bypassing a rollout switch is prohibited during normal operation. It should only be bypassed momentarily by a licensed technician to diagnose a faulty sensor versus a genuine rollout condition.
