Goodman 1370901S 180°F Limit Switch

The Goodman 1370901S is a genuine OEM high-limit switch rated to open at 180°F, used on GMP075-4 gas furnaces and compatible Goodman/Amana models. This thermal safety cutout monitors heat-exchanger temperature and shuts off the gas valve if the furnace overheats — protecting against blocked airflow, a failed blower, or a dirty filter. A limit switch that has failed open causes no-heat calls; one stuck closed defeats a critical safety function.

Specifications

Type: Snap-disc high-limit (auto-reset)
Open temperature: 180°F
Terminals: Dual spade quick-connect
Mount: Flange with mounting screws
OEM Part Number: 1370901S
Fits: Goodman GMP075-4

OEM vs. Generic

The OEM 1370901S is calibrated to Goodman's exact 180°F trip point and correct disc placement. Because this is a safety device, an off-spec generic that trips too high or too low can either nuisance-shut the furnace or fail to protect the heat exchanger. OEM is strongly recommended for any limit control.

Installation Difficulty

Moderate — turn off power and gas, note the two wire positions, remove the mounting screws, and install the replacement in the same location. Confirm proper furnace cycling and temperature rise after install; when in doubt, use a licensed HVAC technician.
