Overview

The Goodman 10123529 is a genuine OEM manual reset limit switch designed as a direct-fit replacement for the Goodman/Amana AMH80804BNBB 80% AFUE gas furnace. This normally-closed safety control opens to cut power to the gas valve if it senses an overheat or flame-rollout condition, and must be manually reset once the fault clears — a deliberate design that forces inspection before the furnace can restart.

Specifications

Type: Manual reset high-limit / rollout safety switch
Function: Opens on overheat/rollout to shut off the gas valve
Action: Normally closed, manual reset button
Equipment: Gas furnace (80% AFUE class)
OEM part number: 10123529
Fits model: AMH80804BNBB

OEM vs. Generic

The OEM 10123529 is calibrated to the exact trip temperature Goodman specifies for this furnace, so it protects the heat exchanger without nuisance trips. Generic switches with the wrong set-point can either trip early (no heat) or fail to protect against a genuine overheat. Because this is a life-safety component, we strongly recommend the OEM part.

Installation Difficulty

Easy (2/5). Disconnect power, note and transfer the wire leads, unscrew the old switch, and mount the new one in the same orientation. Basic hand tools and a nut driver required. Press reset after installation. Typical time: 15–20 minutes.

This is a safety control — never bypass it. Shut off power and gas before servicing, and consult a licensed technician if repeat trips occur.
