Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset limit switch engineered for the AMH80903BXCC 80% AFUE gas furnace and other compatible Goodman/Amana models. This safety component monitors heat exchanger and burner-area temperatures, opening the circuit to shut down the furnace if an unsafe over-temperature or flame rollout condition is detected. Because it is a manual reset design, it must be physically reset after a trip — an intentional safety feature that ensures the underlying fault is inspected before the unit restarts.

Specifications

Type: Manual reset limit / rollout switch
Function: High-temperature and flame rollout protection
Reset: Manual push-button
Compatibility: Goodman/Amana AMH80903BXCC and related 80% furnaces
OEM Part Number: 10123529

OEM vs. Generic

The genuine OEM 10123529 is calibrated to the exact trip temperature specified by Goodman for your heat exchanger, guaranteeing correct safety response. Generic aftermarket switches may carry a different trip point or bracket geometry, risking nuisance trips or, worse, failure to trip. For a code-listed safety device, OEM is strongly recommended.

Install Difficulty: Easy

Two-wire replacement secured by a mounting screw. Always disconnect power before servicing. If the switch trips repeatedly, diagnose the root cause (blocked venting, dirty filter, failing blower) rather than resetting alone.
