Goodman 10728343 Limit Switch

The Goodman 10728343 is a genuine OEM high-limit switch engineered as a direct replacement for the GMPE075-3 gas furnace and other compatible Goodman/Amana units. Mounted on the heat exchanger or burner box, this normally-closed thermal control continuously monitors furnace temperature and opens the circuit to shut off the gas valve if the system overheats — protecting the heat exchanger and household from unsafe operating conditions caused by restricted airflow or blower failure.

Specifications

Type: Automatic high-limit switch
Contacts: Normally closed (opens on over-temperature)
Function: Overheat safety shutoff
Terminals: Quick-connect spade
Calibration: Factory-matched trip/reset set point
Fits: Goodman GMPE075-3
OEM part number: 10728343

OEM vs. Generic

Limit switches are life-safety devices whose trip temperature must match the furnace's exact design. The genuine OEM 10728343 guarantees the correct set point and reliable auto-reset behavior. Generic switches with mismatched calibration can cause nuisance trips or fail to protect the appliance — always choose OEM for safety controls.

Installation Difficulty

Easy to Moderate — shut off power and gas, unplug the two terminals, unscrew the switch, and install the replacement. A qualified technician should verify the trip point and confirm the furnace cycles normally after installation.
