Trip temperature: 150°F (auto-reset)

OEM vs. Generic

The trip temperature and mounting footprint of a limit switch are safety-critical. This OEM switch is calibrated to the exact 150°F set point Goodman specified for this furnace's airflow and heat-exchanger design. Generic switches with the wrong set point can allow dangerous overheating or cause nuisance shutdowns. Never substitute a different temperature rating.

Install Difficulty

Easy (1 of 3). Power off at the disconnect, unplug the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. A 15-minute repair. If the new switch trips repeatedly, diagnose airflow before assuming a bad part.
