The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety cutout for the AMH80403ANAA 80% AFUE gas furnace. This normally-closed switch opens and shuts off the gas valve if the furnace overheats or experiences flame rollout, then requires a manual press of the reset button to restore operation. A tripped or failed limit switch is a frequent cause of a furnace that fires briefly then shuts down (short-cycling) or that stops heating entirely on a safety lockout.

Specifications

Part Number: 10123529
Type: Manual-Reset High-Limit / Rollout Switch
Configuration: Normally Closed (opens on temperature rise)
Reset: Manual push-button
Brand: Goodman / Amana (interchangeable)
Fits: AMH80403ANAA and compatible Goodman/Amana 80% furnaces

OEM vs. Generic

The genuine OEM 10123529 is calibrated to the exact trip temperature specified for your furnace model — critical for a safety component. Generic or mismatched-temperature switches can nuisance-trip at normal operating temps or, worse, fail to trip when they should. For any safety device, the factory OEM part is the only correct choice.

Installation Difficulty

Moderate (3/5). Requires removing the burner-compartment panel, disconnecting two spade terminals, and unscrewing the switch bracket. Basic hand tools and a multimeter to verify continuity are helpful. Always shut off gas and 120V power before servicing. If you're unsure why the switch tripped, have a technician diagnose the underlying overheat cause first.
