Installing the genuine light-blue OEM switch guarantees the correct temperature calibration and mounting fit. Generic or wrong-color substitutes can trip too early (nuisance shutdowns) or too late (inadequate protection).

Disconnect power at the furnace, photograph the wiring, remove the mounting screws, and install the new light-blue switch in the identical location and orientation. Verify the replacement carries the same color code as the one you removed. Reconnect the spade terminals and restore power.
