Goodman 10728343 Limit Switch

The 10728343 is a genuine OEM high-limit temperature switch for the Goodman GMPE100-4 gas furnace and compatible Goodman/Amana equipment. Mounted on the heat exchanger or burner assembly, it senses supply-air temperature and cuts power to the gas valve if the furnace exceeds its safe operating limit — typically caused by a dirty filter, failing blower, or restricted ductwork. This prevents heat-exchanger damage and dangerous overheating.

Specifications

OEM Part Number: 10728343
Type: High-limit temperature switch
Function: Opens on over-temperature to de-energize gas valve
Terminals: Spade connectors
Fits: Goodman GMPE100-4 and compatible furnaces

OEM vs. Generic

Factory Goodman limit switches are matched to the furnace's designed trip temperature and mounting footprint. Aftermarket substitutes can trip early (short cycling and no heat) or late (leaving the furnace unprotected). For a safety control this critical, the genuine OEM part is the reliable choice.

Installation Difficulty

Moderate (3/5). Replacement involves two mounting screws and two wire connectors and takes about 15–20 minutes. Always disconnect gas and electrical power before service, and address the cause of any repeated tripping — never bypass a limit switch.
