Compatible with: Fits for most Intertherm, Miller, Nordyne gas furnaces models MGH or M1G
Replace part number: 626337 626337R 626337B 6263370
Safety threshold: When the temperature exceeds the upper limit, immediately cut off the power supply of the burner/igniter to prevent deformation, cracking, or fire risk of the heat exchanger
Automatic reset: After the temperature drops to a safe range, the contact will automatically close and resume combustion without manual intervention, suitable for unmanned scenarios
System linkage: It is linked with components such as pressure switches and flame sensors to form multiple safety barriers. In case of abnormalities, it is forced to shut down and trigger an alarm, making it easy to quickly locate faults
