The Goodman B1370198 Primary Limit Switch is the genuine OEM 150°F auto-reset high-limit control for the AMS81155CXAA 80% AFUE gas furnace and compatible Goodman/Amana models. Mounted on the heat-exchanger/plenum bulkhead, it is the main overheat safety: if supply-air temperature exceeds the set point due to restricted airflow, it opens to shut down the burners and protect the heat exchanger.

Specifications

OEM vs. Generic

As the furnace's main overheat protection, this control must trip at the exact factory temperature. OEM B1370198 delivers the correct 150°F set point, terminal style, and mounting footprint. Generic limits with the wrong rating can nuisance-trip or allow damaging overheat — OEM is strongly recommended for this safety device.

Why Replace It

A failed primary limit produces repeated no-heat lockouts or, if stuck open, a total no-heat condition. Replace it with the genuine part and correct any airflow restriction (dirty filter, blocked ducts, weak blower) that may be causing high plenum temperatures.

Install difficulty: Easy. About 15–20 minutes: cut power, remove two mounting screws and the spade terminals, and fit the new switch to the same bracket. Verify normal heat cycling afterward.
