The Goodman B1370198 Primary Limit Switch is a genuine OEM high-limit temperature control for the AMV80905CXBB gas furnace and compatible Goodman and Amana units. Mounted in the heat-exchanger air stream, it protects the furnace from overheating by opening the gas/ignition circuit when supply-air temperature reaches its 150°F limit — commonly caused by restricted airflow, a dirty filter, or a failed blower.

Specifications

Trip temperature: 150°F (open on rise)
Type: Primary high-limit switch, auto-reset
Configuration: Normally closed (SPST)
Fits: Goodman / Amana AMV80905CXBB and compatible gas furnaces
OEM part number: B1370198

OEM vs. Generic

The OEM Goodman limit is matched to the furnace's cabinet cutout, insertion depth, and factory temperature calibration. Universal replacements often require re-drilling and may trip early or late, reducing efficiency or masking a real airflow fault. The OEM part guarantees correct fit and protection.

Installation Difficulty: Easy

Two screws and two spade terminals — about 15 minutes with power disconnected. Confirm proper airflow (clean filter, open registers) and inspect the blower before returning the unit to service.
