The Goodman B1370198 Primary Limit Switch is the genuine OEM high-limit safety control for the Goodman/Amana AMH81155CXAA gas furnace and related 80% AFUE units. This switch sits in the supply-air stream above the heat exchanger and shuts off the gas valve if the plenum temperature climbs too high, preventing heat-exchanger damage and unsafe operation.

Specifications

Type: Primary high-limit switch
Trip point: 150°F (opens on rise)
Reset: Automatic
Terminal: 1/4" quick-connect spade
OEM Part Number: B1370198

OEM vs. Generic

The factory B1370198 is set to Goodman's precise 150°F opening temperature, ensuring the furnace cycles safely without premature shutdowns. Generic substitutes frequently drift from spec, leading to short-cycling and comfort complaints. Because the primary limit directly controls the gas valve, we strongly recommend the genuine OEM part.

Installation Difficulty

Easy (2/5). Kill power at the breaker, remove the two retaining screws on the limit, transfer the two spade connectors, and reinstall in the same orientation. Typical replacement takes 10–15 minutes with a nut driver. Verify no voltage before you begin.
