Description
The Reznor 210763 is a 220°F high oil temperature limit switch engineered to protect oil-fired heating equipment from dangerous overtemperature conditions. When oil temperature reaches the 220°F trip point, this limit switch interrupts the control circuit, shutting down the burner and preventing equipment damage, heat exchanger failure, or fire hazard.
As a genuine Reznor OEM replacement part, the 210763 is designed for precise fit and reliable performance in Reznor oil-fired unit heaters and related heating systems. Using an authentic Reznor component ensures proper calibration, long service life, and maintained equipment warranty compliance.
