The Goodman 10123529 is a genuine OEM manual reset high-limit switch designed as a direct-fit replacement for the AMEC800403ANAA Amana/Goodman gas furnace and compatible models. This safety control opens the ignition circuit if the furnace exceeds its safe operating temperature, protecting the heat exchanger and cabinet from overheating and requiring a deliberate manual reset before the furnace can restart.

Specifications

Type: Manual reset high-limit / rollout safety switch
Reset: Manual (push-button)
OEM Part Number: 10123529
Fits: AMEC800403ANAA and compatible Goodman/Amana furnaces
Function: Opens circuit on overtemperature to prevent unsafe operation

OEM vs. Generic

A manual reset limit switch is a last-line safety device with a specific trip temperature. The genuine OEM switch ensures the correct temperature rating, mounting footprint, and terminal orientation. A generic switch with a different trip point can either nuisance-trip or fail to protect the furnace. For overheat protection, always install the OEM-specified part.

Installation Difficulty

Easy (1/5). Disconnect power to the furnace, remove the two spade terminals and mounting screws, install the new switch in the same location and orientation, and reconnect the wiring. Press the reset button after install. Typically a 15-minute job.

Turn off power and gas before servicing. If the limit has tripped, diagnose the underlying overheat cause; if unsure, consult a licensed HVAC technician.
