The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-limit safety control for AMEC800805CNAB gas furnaces. This switch monitors temperature in the heat-exchanger or burner area and opens the circuit to shut down the furnace if it overheats — a critical safety function that protects against blocked airflow, blower failure, or flame rollout. Its manual-reset design requires a technician to press the button after a trip, ensuring the underlying fault is diagnosed rather than silently ignored.

Type: Manual reset high-limit safety switch

OEM vs. Generic

This OEM Goodman switch is calibrated to the exact trip temperature and mounting footprint your furnace's safety logic depends on. Generic limit switches with a different set point can trip prematurely (nuisance shutdowns) or, worse, too late — compromising the safety margin. On a safety-critical control, always use the OEM-specified part.

Installation Difficulty

Easy. Turn off power at the breaker, disconnect the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. Typically a 10–15 minute job with a nut driver. If the switch was tripping repeatedly, have the root cause (airflow, blower, exchanger) evaluated before returning the furnace to service.
