The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control engineered for the AMS81005CXAC furnace and other compatible Goodman and Amana gas furnace platforms. This rollout/high-limit switch monitors heat exchanger and burner-compartment temperature and interrupts the gas valve circuit if an unsafe over-temperature or flame-rollout condition is detected — a critical protection against overheating and combustion faults.
Because it is a manual reset device, a tripped switch will stay open until the underlying issue (blocked flue, dirty burners, cracked heat exchanger, or restricted airflow) is corrected and the button is physically pressed. This ensures a technician inspects the furnace before it can re-fire.
OEM vs. Generic: This genuine Goodman OEM switch is calibrated to the exact trip temperature your furnace's control sequence expects, guaranteeing proper safety response. Generic replacements may carry a different trip point or terminal spacing, which can cause nuisance trips or fail to protect the heat exchanger correctly. For a safety-critical component, OEM is strongly recommended.
Install Difficulty: Easy (1/5). Two spade terminals and two mounting screws — replaceable in minutes with power disconnected. Always shut off gas and electrical power before servicing.
