Goodman B1370190 Primary Limit Switch (210°F)

The Goodman B1370190 is a genuine OEM primary high-limit switch built for the DMS80453ANA furnace and matching Goodman/Amana platforms. Mounted on the heat exchanger or blower deck, it shuts down the burners when supply-air temperature reaches its 210°F setpoint — preventing heat-exchanger damage and unsafe operating conditions from restricted airflow or a failed blower.

Specifications

Trip temperature: 210°F (open on rise)
Type: Primary high-limit switch
Function: Overtemperature burner cutoff
Fits: Goodman DMS80453ANA and related 80% furnaces
OEM part number: B1370190
Brand: Goodman (also fits Amana)

OEM vs. Generic

The OEM Goodman primary limit is matched to the factory 210°F setpoint and mounting footprint. Generic switches often carry approximate calibration and can trip early or late, producing intermittent no-heat calls. Because this switch is your furnace's main overheat safeguard, we strongly recommend the OEM part.

Installation Difficulty

Easy (1/5). Two spade terminals and one or two mounting screws. Disconnect power and gas before beginning, and verify airflow (filter/blower) is clear so the new switch isn't triggered by an underlying fault.
