The Goodman 1370906S Limit Switch is the factory-original high-limit safety control for GUPI120-5 gas furnaces. It monitors heat-exchanger temperature and opens the burner circuit if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure. A limit switch that trips prematurely or fails open will shut the furnace down or cause short-cycling; this OEM switch restores correct, safe operation.

Specifications

OEM Part Number: 1370906S
Part Type: High-Limit Safety Switch (auto-reset)
Trip Temperature: 150°F
Insertion Length: 7 inch
Compatible Model: Goodman GUPI120-5 gas furnace
Fit: Direct OEM replacement — matches factory temperature and length

OEM vs. Generic

This genuine Goodman switch is calibrated to the exact 150°F trip point and 7-inch probe depth specified for the GUPI120-5 heat exchanger. Because a limit switch is a life-safety device, matching the OEM trip temperature and insertion length is critical — a substitute with a different setpoint can either nuisance-trip or fail to protect the exchanger. Always match OEM specs here.

Installation Difficulty

Easy. Disconnect power, remove the two mounting screws, transfer the wire leads, and install the new switch at the same depth. About 15–20 minutes. Because this is a gas-furnace safety control, professional installation is recommended.
