Common Questions:

What happens if the 220-250F AUTO Limit Switch fails?
If the switch stays open, the furnace will likely run the blower continuously while disabling the burners. If it stays closed, the system loses its primary defense against overheating, which can crack the heat exchanger.

Is the S1-025-32651-000 interchangeable with other temperature ranges?
No. You must match the specific 250°F open and 220°F close settings. Installing a switch with a different thermal profile can lead to nuisance tripping or dangerous overheating.

Does this switch require professional calibration?
This is a factory-calibrated, fixed-temperature component. No field adjustment is required or possible; simply ensure the mounting surface is clean for accurate thermal transfer.
