Goodman 10123529 Manual Reset Limit Switch

The 10123529 is a genuine OEM Goodman manual reset high-limit switch designed for the WFD18045S3AXCB gas furnace and compatible Goodman/Amana models. This is a critical safety component: it monitors temperature in the burner or heat exchanger area and opens the circuit to shut down the furnace if it detects an overheat or flame-rollout condition, helping prevent damage to the heat exchanger and reducing fire risk.

Specifications

Part Type: Manual reset high-limit / rollout safety switch
Reset: Manual push-button (does not auto-reset — indicates a fault to investigate)
Function: Opens on overtemperature to de-energize the gas valve
Fits: Goodman WFD18045S3AXCB and select Goodman/Amana furnaces
OEM Part Number: 10123529

OEM vs. Generic

Because this is a life-safety device, OEM is strongly recommended. The genuine 10123529 is calibrated to the exact factory trip temperature for your furnace. Generic switches with a different setpoint can nuisance-trip or, worse, fail to trip when needed. Do not substitute a switch with an unverified temperature rating.

Installation Difficulty

Moderate (3/5). Requires shutting off power and gas, removing the burner-compartment panel, disconnecting spade terminals, and transferring the switch. Note wire positions before removal. If a manual reset switch has tripped, always diagnose the root cause (restricted airflow, dirty filter, blocked flue) before resetting. When in doubt, use a licensed HVAC technician.
