The genuine Goodman 10123539 Manual Reset Limit Switch is a high-temperature safety control for ACSS961005CNAA gas furnaces. Mounted near the burner/heat-exchanger area, it trips and cuts power to the gas valve if it detects flame rollout or excessive temperature — and because it is a manual reset device, it stays open until a technician presses the button, ensuring a serious fault is investigated before the furnace can fire again.

Specifications

Part Type: Manual reset rollout / limit safety switch
OEM Part Number: 10123539
Brand: Goodman (OEM)
Fits Model: ACSS961005CNAA gas furnace

OEM vs. Generic

This factory OEM Goodman switch is calibrated to the precise trip temperature specified for your furnace. Generic limit switches with mismatched trip points can nuisance-trip or, worse, fail to trip when needed. Because this is a primary safety component, OEM accuracy is strongly recommended.

Installation Difficulty

Moderate (3 of 5). Shut off power and gas, disconnect the two spade terminals, remove the mounting screws, install the new switch, and reconnect. Basic hand tools and electrical care required.

If a safety switch has tripped, diagnose the underlying cause (blocked flue, dirty burner, cracked heat exchanger) before resetting or replacing.
