Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual-reset high-limit safety switch for the AMH81205DXBB gas furnace and compatible Goodman/Amana models. This normally-closed thermal switch monitors for overheating or flame rollout conditions and opens the circuit to shut down the furnace if a dangerous temperature is reached. Because it is a manual-reset device, it must be physically reset after tripping — a deliberate design that flags a fault for inspection. A failed or nuisance-tripping switch should be replaced only with the exact OEM part to preserve the furnace's safety chain.

Specifications

OEM Part Number: 10123529
Type: Manual reset high-limit / rollout switch
Contacts: Normally closed (opens on overtemp)
Reset: Manual (push-button)
Fits: Goodman & Amana AMH81205DXBB gas furnaces
Brand: Goodman (OEM)

OEM vs. Generic

The genuine Goodman 10123529 is calibrated to the precise trip temperature specified for this furnace's burner box and mounting location. Generic limit switches with the wrong trip point can trip early (nuisance shutdowns) or, worse, fail to trip when needed — compromising safety. This is a safety component; OEM is strongly recommended.

Installation Difficulty

Easy to Moderate. Two-wire spade-terminal connection with one or two mounting screws; typically a 10–15 minute job. If the switch keeps tripping after replacement, have the furnace's airflow and heat exchanger inspected. Shut off gas and power before servicing.
