Goodman 10123529 Manual Reset Limit Switch

The genuine OEM Goodman 10123529 is a manual reset limit (rollout) switch engineered for the Amana AMH80805CNBB 80% AFUE gas furnace and other compatible Goodman/Amana 80,000 BTU models. This safety control monitors for flame rollout and overheat conditions at the burner box; when a fault trips the switch, the furnace shuts down and the switch must be manually reset once the underlying cause is cleared — a design that prevents dangerous automatic restarts.

Specifications

Type: Manual reset flame rollout / limit switch
Reset: Push-button manual reset
Fit: Amana/Goodman AMH80805CNBB furnace
Function: High-temperature safety cutoff
Part number: 10123529 (OEM)

OEM vs. Generic

This is a genuine OEM Goodman/Amana part built to factory temperature and reset specifications. Generic aftermarket switches may trip at incorrect thresholds or fail to seat correctly against the burner shield, risking nuisance lockouts. Choosing OEM guarantees exact fit and code-compliant safety performance.

Installation Difficulty

Easy (2/5). Two-screw mount with quarter-inch spade terminals — most homeowners can replace it in under 15 minutes with the power off. If the switch keeps tripping after replacement, have the heat exchanger and venting inspected by a licensed HVAC technician.
