The Goodman 10728343 Limit Switch is a genuine OEM temperature safety control for the Goodman GMP100-5 furnace. The high-limit switch continuously monitors plenum and heat-exchanger temperature, interrupting the burner circuit if the furnace exceeds its safe operating range — commonly caused by a dirty filter, closed registers, or a failing blower. A faulty limit switch can cause short-cycling, no-heat calls, or nuisance shutdowns, making it a key diagnostic and replacement part.

Specifications

Part Number: 10728343
Type: High-limit temperature safety switch
Function: Overtemperature burner cutoff
Brand: Goodman (OEM)
Compatible Model: GMP100-5
Equipment Type: Gas Furnace

OEM vs. Generic

Our OEM Goodman limit switch is factory-calibrated to the exact trip and reset temperatures the GMP100-5 was designed around — the safest choice for a protective control. Our Generic equivalent matches the temperature rating and mounting footprint at a reduced cost for budget-minded repairs. For any safety switch, verify the correct temperature rating before installing.

Installation Difficulty

Rating: Easy (1/3). The switch mounts to the burner box or heat-exchanger panel and uses push-on terminals. Always disconnect power before servicing. If the switch has been tripping, clear the airflow restriction or blower fault first — replacing the switch alone won't fix an overheating furnace.

In stock and ships fast. Verified fit for the GMP100-5.
