Goodman 10123529 Manual Reset Limit Switch

The 10123529 is a genuine OEM manual-reset high-limit / rollout safety switch for the Goodman/Amana AMEC800804BXAB gas furnace. This thermally activated control opens the circuit and shuts down the furnace if it detects an over-temperature or flame-rollout condition, protecting the heat exchanger and preventing unsafe operation. Because it's a manual-reset device, it must be physically reset after a trip — and a switch that trips repeatedly or fails closed/open should be replaced with the exact factory part.

Specifications

OEM Part Number: 10123529
Category: Limit / Safety Switch
Type: Manual reset, thermally activated high-limit / rollout
Fits Model: AMEC800804BXAB (Goodman / Amana gas furnace)
Function: Over-temperature and flame-rollout safety shutoff
Fit Type: Direct OEM replacement

OEM vs. Generic

This is a life-safety component, so the trip temperature and mounting must be exact. OEM switches are calibrated to the precise cut-out point Goodman specified for this furnace and mount in the factory location for accurate sensing. Generic switches with the wrong trip rating or bracket can nuisance-trip, fail to trip when needed, or read the wrong temperature — never substitute a mismatched limit control on a safety circuit.

Installation Difficulty

Rating: Easy–Moderate (2 of 5). Cut power to the furnace, note and disconnect the two wire leads, remove the mounting screws, install the new switch in the same orientation, and reconnect. Usually 15–30 minutes. After installation, restore power, confirm the furnace cycles normally, and verify the switch is not tripping during a full heat cycle. If it trips again, diagnose the underlying overheating or rollout cause before returning to service.
