Reznor 121866 Thermal Switch Optimized Signal: Features an extendedFor veteran contractors servicing industrial heating equipment, the Reznor 121866 Thermal Switch is a critical OEM component designed for high precision fan control and limit protection. This F190 30F thermal thermostat is engineered to monitor internal cabinet temperatures, ensuring the blower activates only when the heat exchanger reaches an optimal 190F. By deactivating the blower once temperatures drop below 30F, this switch prevents the
