The Goodman 1370908S High-Limit Switch is a genuine OEM safety control engineered for the Goodman GSMS080-4 gas furnace. This 7-inch insert limit switch monitors heat-exchanger temperature and opens the burner circuit at its 160°F trip point to prevent overheating, protecting your furnace and home from unsafe operating conditions.
This is a factory OEM Goodman component, guaranteeing the exact temperature calibration, terminal spacing, and mounting geometry your furnace board expects. Generic universal limits may require rewiring or trip at incorrect temperatures — the OEM part is a true drop-in with no guesswork.
A basic repair for a technician or a confident DIYer. Shut off power and gas, disconnect the two spade terminals, remove the mounting screws, and swap in the new switch. Most installs take under 15 minutes. Always confirm power is off before servicing.
