The Goodman B1370190 Primary Limit Switch is a genuine OEM safety control engineered for AMH80453ANAC gas furnaces and other compatible Goodman/Amana 80% AFUE units. This normally-closed thermal switch continuously monitors heat-exchanger temperature and interrupts the gas valve and igniter circuit if the furnace overheats, protecting the heat exchanger, blower, and surrounding components from thermal damage.

Specifications

Cutout temperature: 210°F (opens on rise)
Type: Automatic-reset primary high-limit switch
Configuration: Normally closed (SPST)
Fit: Direct replacement for Goodman/Amana AMH80453ANAC
Mounting: Flange-mount, matches OEM footprint

OEM vs. Generic

Our genuine OEM B1370190 is calibrated to the exact 210°F trip point your furnace's control board expects. Generic universal limit switches often carry loose temperature tolerances that cause premature short-cycling or, worse, allow overheating. Choosing OEM guarantees correct calibration, proper reset behavior, and factory-matched terminal spacing—no wiring adapters or guesswork.

Installation Difficulty

Easy (1/5). Replacement typically takes 10–15 minutes: shut off power and gas, unplug the two spade terminals, remove two mounting screws, and swap in the new switch. Always confirm the part number on your existing switch before installing. If you're not comfortable working near the gas valve or burner assembly, consult a licensed HVAC technician.
