Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset limit switch engineered as a direct-fit replacement for the AMSS921205DNAA gas furnace and compatible Goodman/Amana models. This safety-critical control monitors flame rollout and over-temperature conditions inside the burner compartment, cutting power to the gas valve if unsafe heat is detected. Because it requires a manual reset, it forces a service inspection after a trip — exactly what a properly designed furnace safety chain should do.

Specifications

Part type: Manual reset rollout / limit switch
Reset style: Manual push-button reset
Fits: Goodman & Amana furnaces including AMSS921205DNAA
Function: Flame rollout / high-limit safety cutoff
Terminals: Standard 1/4" quick-connect spades
Brand: Genuine Goodman OEM

OEM vs. Generic

The genuine Goodman OEM switch is calibrated to the exact trip temperature specified for your furnace, ensuring the safety chain behaves as the manufacturer intended and preserving warranty coverage. Universal generic switches can vary in trip point and mounting, risking nuisance lockouts or, worse, a switch that fails to protect the heat exchanger. For a safety device, OEM is the recommended choice.

Installation Difficulty

Rating: Easy (2/5). Replacement typically takes 10–15 minutes with basic hand tools. Shut off power and gas at the furnace, photograph the wiring, transfer the spade connectors to the new switch, and mount it in the original bracket. If the switch trips repeatedly after replacement, have a licensed HVAC technician inspect for a cracked heat exchanger or airflow restriction.

Always de-energize the furnace before servicing. When in doubt, consult a qualified technician.
