Goodman B1370198 Primary Limit Switch (150F)

The B1370198 primary limit switch is a genuine OEM safety control for the Goodman/Amana AMV80905CXBA furnace and compatible 80% AFUE gas furnace platforms. This normally-closed thermal cutout monitors heat-exchanger and plenum temperature and opens the ignition/gas circuit if the furnace overheats — protecting the equipment and your home from unsafe temperature rise caused by restricted airflow, a dirty filter, or a failed blower.

Specifications

Open (trip) temperature: 150°F
Type: Normally-closed automatic-reset primary limit
Circuit: Low-voltage 24V safety string
Fits: Goodman / Amana AMV80905CXBA and related 80% single-stage furnaces
OEM Part Number: B1370198

OEM vs. Generic

The OEM B1370198 is calibrated to the exact 150°F trip point and mounting footprint specified by Goodman, guaranteeing correct fit and reliable high-limit protection. A generic equivalent may save a few dollars but can vary in trip temperature and bracket geometry, risking nuisance lockouts or improper safety response. For a safety-critical control, we recommend OEM.

Install Difficulty

Easy (2/5). Two mounting screws and two spade terminals. Always shut off gas and power at the disconnect before servicing. Typical replacement time is 10–15 minutes.
