Goodman 10123518 Manual Reset Limit Switch

The Goodman 10123518 is a genuine OEM manual-reset high-limit safety switch for the GCH90704CXAA gas furnace. Mounted in the burner or heat-exchanger area, it senses excessive temperature and opens the control circuit to cut power to the burners during an overheat or flame-rollout event. As a manual reset switch, it stays open until the push-button is pressed, ensuring a technician or homeowner investigates the fault before the furnace is allowed to fire again. This is a primary fire-safety device on high-efficiency Goodman furnaces.

Specifications

OEM Part Number: 10123518
Type: Manual reset high-limit / rollout safety switch
Reset: Manual (push-button)
Function: Opens circuit on overtemperature to shut down burners
Compatible Model: GCH90704CXAA (and related Goodman/Amana furnaces)

OEM vs. Generic

The 10123518 and 10123517 differ by trip temperature and/or mounting position, so substituting the wrong switch — or a generic equivalent — can defeat the safety it is meant to provide. The OEM 10123518 is factory-calibrated to Goodman's specified set point for the GCH90704CXAA, so it protects the heat exchanger without false trips. For a safety component, always order by exact OEM part number.

Installation Difficulty

Moderate (2/5). Disconnect power and gas, photograph the wiring, remove the spade connectors and mounting screws, fit the new 10123518 in the identical position, and reconnect the leads. If it had tripped, correct the underlying cause (restricted airflow, blocked venting, failed inducer) before restoring operation. Consult a licensed HVAC professional if you are not comfortable with furnace safety circuits.

Genuine OEM Goodman safety part. Please verify your model number before ordering.
