The genuine Goodman 10123529 Manual Reset Limit Switch is a critical overtemperature safety device for AMEH800603BXAA gas furnaces. It monitors heat-exchanger temperature and cuts power to the gas valve if the furnace overheats — commonly from a blocked filter, failed blower, or restricted ductwork. Because it is a manual-reset design, it will not automatically re-energize, forcing a technician to inspect the cause before the furnace can run again.

Specifications

Part number: 10123529
Part type: Manual reset high-limit switch
Function: Overtemperature safety cutout
Reset: Manual (push-button)
Fits: Goodman & Amana AMEH800603BXAA gas furnaces

OEM vs. Generic

This OEM switch is calibrated to Goodman's exact trip and reset temperature for the AMEH800603BXAA heat exchanger. Generic limit switches may trip at the wrong threshold — nuisance-tripping during normal operation or, worse, failing to trip before dangerous temperatures are reached. Always match OEM temperature ratings on safety controls.

Installation Difficulty

Easy (2/5). Power down the furnace, disconnect the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. Restore power and verify normal operation. Typical install 10–15 minutes.
