OEM vs. Generic

The 140°F calibration on this switch is specific to the GMPN120-5 venting design. This factory-original Goodman part guarantees the correct trip and reset points, avoiding the short-cycling and false lockouts common with mismatched aftermarket switches. For a safety limit, OEM is the right call.

Installation Difficulty

Easy (2/5). A quick 10-minute replacement: disconnect power and gas, remove the mounting screws, move the spade connectors to the new switch, and reinstall in the same orientation. If the switch was tripping, verify the flue and heat exchanger are clear before restoring service. When in doubt, use a licensed HVAC professional.
