Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset high-limit switch engineered for the GDH80403AXBC gas furnace and compatible Goodman/Amana 80% AFUE models. This safety control opens the burner circuit if the heat exchanger or blower compartment exceeds its rated temperature, protecting your furnace from overheating caused by restricted airflow, a failed blower, or a dirty filter. Because it is a manual reset device, it requires a deliberate push of the reset button after a fault clears — alerting the homeowner or technician that a limiting condition occurred.

Specifications

Function: Opens burner ignition circuit on over-temperature
Reset: Push-button manual reset
Fitment: Goodman GDH80403AXBC and compatible 80% AFUE furnaces
OEM Part Number: 10123529

OEM vs. Generic

The genuine OEM 10123529 is calibrated to the exact trip temperature specified for your furnace, ensuring the safety circuit behaves as the manufacturer intended. Aftermarket switches often use approximate trip points that can cause nuisance trips or, worse, delayed protection. Choosing OEM preserves your equipment warranty and guarantees a drop-in fit with the factory wiring harness and mounting bracket.

Installation Difficulty

Rating: Easy (2/5). Replacement involves shutting off gas and power, disconnecting two spade terminals, and swapping a single bracket-mounted switch. Most handy homeowners complete it in 15–20 minutes with a nut driver. If the switch trips repeatedly after replacement, have a licensed HVAC technician diagnose the underlying airflow or combustion problem.
