The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for the Amana/Goodman AMH80803BXBB 80% AFUE furnace. This normally-closed switch opens to shut off the gas valve if it senses abnormal heat — typically from a flame rollout or blocked heat exchanger — and stays open until manually reset. A tripped or failed switch is a common cause of a furnace that lights briefly and then locks out.

Specifications

Part Number: 10123529
Type: Manual reset high-limit / rollout safety switch
Contacts: Normally closed, opens on over-temperature

Fits Model: AMH80803BXBB

OEM vs. Generic

The OEM 10123529 is calibrated to the exact trip temperature and mounting footprint specified for this furnace. Generic limit switches may carry a different set point or bracket, which can lead to nuisance lockouts or, worse, failure to cut off during a genuine fault. For a life-safety component, use the factory OEM switch.

Installation Difficulty

Easy to Moderate — power down the furnace, disconnect the two spade terminals, unscrew the switch, and reinstall. If the switch tripped, always diagnose the root cause (rollout, dirty burners, restricted venting) before returning the unit to service.
