The Goodman 1370908S High Limit Switch is a genuine OEM safety control designed for GMPN060-3 gas furnaces. This 7-inch insertion limit switch opens the burner circuit when heat exchanger temperatures exceed the 160°F trip point, protecting your furnace from overheating caused by restricted airflow, a dirty filter, or a failing blower. It automatically resets once the temperature drops back into a safe range.
This is a factory-authentic Goodman component — the same switch that shipped with your furnace. Generic aftermarket limit switches often use looser temperature tolerances and shorter service life, which can cause nuisance lockouts or fail to trip at the correct setpoint. The OEM 1370908S guarantees the exact 160°F calibration and 7-inch fit your control board expects, with no wiring adapters required.
Easy (1 of 3). Disconnect power, remove the two mounting screws, unplug the spade terminals, and swap in the new switch. Most homeowners with basic tools complete this in 15–20 minutes. Always shut off gas and electrical power before servicing. If your furnace continues to trip on limit after replacement, inspect the filter, blower, and ductwork for airflow restrictions.
