Goodman 10123529 Manual Reset Rollout Limit Switch

The Goodman 10123529 is a genuine OEM manual-reset rollout limit switch engineered for the AMS81405DNBA gas furnace and compatible Goodman & Amana models. This normally-closed safety device monitors for flame rollout at the burner box and trips open to shut down the furnace if it detects excessive heat or an improper burn — a critical protection against fire and carbon monoxide events. Because it is a manual reset control, a trip requires a physical button press after the underlying fault is corrected, ensuring a technician inspects the system before the furnace restarts.

Specifications

Type: Manual reset rollout / flame rollout limit switch
Contacts: Normally closed (SPST), opens on temperature rise
Reset: Manual push-button
Mounting: Burner box bracket, OEM footprint
Fits: Goodman/Amana AMS81405DNBA and related gas furnaces

OEM vs. Generic

The genuine OEM 10123529 is calibrated to the exact trip temperature and mechanical fit specified by Goodman, guaranteeing correct clearance in the burner compartment and reliable safety response. Generic aftermarket switches may vary in trip point and bracket geometry, which can cause nuisance trips or improper protection. For a safety-critical control, OEM is strongly recommended.

Install Difficulty

Easy (2/5). Power off at the disconnect, remove two spade connectors and the mounting screw, swap in the new switch, and reconnect. Basic hand tools only. Always diagnose the root cause of any rollout trip before replacing this part.
