Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset limit switch (rollout/high-limit safety cutout) engineered for the GDH80403ANAA gas furnace and other compatible Goodman/Amana models. This safety control opens the gas valve circuit when it senses abnormal heat or flame rollout at the burner box, shutting the furnace down to prevent overheating. Unlike auto-reset controls, this switch stays open until manually reset — a deliberate safety feature that forces a technician to diagnose the root cause before the unit restarts.

Specifications

Type: Manual reset limit / flame rollout switch
Fits: Goodman GDH80403ANAA 80% gas furnace
Function: High-limit safety cutout, opens on overheat
Reset: Manual push-button
Brand: Goodman OEM

OEM vs. Generic

Our genuine OEM 10123529 is calibrated to the exact factory trip temperature for your furnace, guaranteeing proper safety operation and preserving your equipment warranty. Aftermarket generics may trip at incorrect temperatures, causing nuisance shutdowns or, worse, failing to protect the unit. For a critical safety component, OEM is strongly recommended.

Installation Difficulty

Easy (1/5). A basic replacement using two spade connectors and one or two mounting screws. Always shut off power and gas before servicing. If your switch keeps tripping, do not simply reset it — have the flue, heat exchanger, and burners inspected by a qualified technician.
