The Goodman 10123533 Manual Reset Limit Switch is a genuine OEM safety control for the GMH950453BXAD 96% AFUE gas furnace and compatible Goodman/Amana condensing models. This high-limit switch monitors heat-exchanger and burner temperatures and cuts power to the gas valve if the furnace overheats — protecting against fire and heat-exchanger damage. Because it is a manual-reset design, it must be pressed to restore operation after a trip, alerting you to conditions like a blocked flue, dirty filter, or blower failure. A failed switch causes no-heat or short-cycling faults.

OEM vs. Generic

The OEM Goodman 10123533 is calibrated to the exact trip temperature and mounting footprint specified for your furnace, ensuring reliable, code-correct safety operation. The Generic equivalent offers a compatible temperature rating at a lower price. Because this is a safety-critical component, we recommend the OEM part whenever possible.

Installation Difficulty

Moderate. Shut off power and gas, remove the burner/control access panel, label and disconnect the two spade terminals, unscrew the old switch, and mount the replacement in the same orientation. About 15–20 minutes with basic hand tools. Test heating operation and confirm the switch resets correctly — if unsure, use a licensed HVAC technician.
