Goodman 10123529 Manual Reset Rollout Limit Switch

The Goodman 10123529 is a genuine OEM manual reset rollout limit switch engineered for the Goodman/Amana AMH80603AXBB gas furnace and compatible 80% AFUE models. This safety-critical component monitors for flame rollout and heat-exchanger overheating, cutting power to the gas valve if unsafe temperatures are detected. Because it is a manual reset device, it must be physically reset after a trip — a deliberate design that forces a technician to inspect the cause before the furnace can fire again.

Specifications

Type: Manual reset rollout / flame limit switch
OEM Part Number: 10123529
Fits: Amana/Goodman AMH80603AXBB and related 80% furnaces
Reset: Manual push-button
Function: High-limit safety cutoff

OEM vs. Generic

This is the genuine OEM Goodman part, calibrated to the exact factory trip temperature for your furnace. Generic aftermarket switches are typically cheaper but may use a different set point, which can cause nuisance trips or, worse, fail to open at the correct temperature. For a safety device, OEM calibration matters.

Installation Difficulty

Easy — A two-wire spade-terminal replacement that mounts with two screws. Always shut off power and gas before servicing. Recommended for HVAC technicians; DIYers should confirm the switch, not an upstream issue, is the actual fault.

Fits Goodman and Amana furnaces sharing the AMH80603AXBB platform. Contact info@nationalhvacparts.com for fitment help.
