The Goodman 10123538 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the AMSS920403ANAA 92% single-stage gas furnace and compatible Goodman/Amana models. This normally-closed switch opens the gas-valve circuit if it senses an overheat or flame-rollout condition, shutting the furnace down until an operator manually presses the reset button — a critical protection against heat-exchanger damage and unsafe combustion.

Specifications

OEM Part Number: 10123538
Fits: Goodman & Amana AMSS920403ANAA and related 92% furnaces

OEM vs. Generic

Genuine Goodman limit switches are calibrated to the exact trip temperature the furnace was engineered around. A generic switch with the wrong setpoint can nuisance-trip or, worse, fail to trip when it should. On a safety device that guards against flame rollout, always fit the correct OEM part.

Installation Difficulty

Moderate (2/5). Remove power and gas, unplug the two spade terminals, unscrew the switch, and mount the replacement in the same orientation. Verify operation on restart. If you are not comfortable with furnace wiring, hire a licensed HVAC technician.

Fast shipping and a 30-day return policy. Restore your furnace's safety chain with the genuine Goodman 10123538.
