Goodman 1370908S Limit Switch (160°F, 7-inch)

The Goodman 1370908S is a genuine OEM high-temperature limit switch rated to 160°F with a 7-inch insertion probe, built for the Goodman GSM080-4 gas furnace. This safety control monitors heat-exchanger temperature and opens the burner circuit if the furnace overheats—typically caused by restricted airflow, a dirty filter, or a failed blower. A tripped or failed limit switch is a common cause of no-heat and lockout conditions.

Specifications

OEM Part Number: 1370908S
Part Type: High-Limit Safety Switch
Trip Temperature: 160°F
Probe Length: 7 inches
Compatible Model: GSM080-4 gas furnace
Brand: Goodman
Equipment: Furnace

OEM vs. Generic

The genuine Goodman 1370908S guarantees the exact 160°F trip point and 7-inch probe length required for the GSM080-4's heat exchanger geometry. Installing a switch with the wrong temperature rating or probe length compromises a critical safety function. Because this is an overheat-protection device, OEM is strongly recommended—do not substitute.

Installation Difficulty

Moderate (2/5). Shut off power and gas, remove the two mounting screws, disconnect the spade terminals, and install the replacement in the same orientation. Verify the 160°F rating and 7-inch length match the original before installing. If the furnace has been repeatedly overheating, diagnose the airflow cause before returning it to service.
