Goodman B1370198 Primary High-Limit Switch (150°F)

The B1370198 is a genuine OEM 150°F primary limit switch for the Goodman GMV80704BXBA 80% AFUE gas furnace. Mounted on the heat exchanger/plenum, this high-limit control monitors supply-air temperature and shuts off the burners if the furnace overheats — typically from restricted airflow such as a dirty filter, closed registers, or a failing blower. A tripped or failed limit is a common cause of short-cycling and 'no heat' complaints.

Specifications

Part Number: B1370198
Trip Temperature: 150°F (auto-reset high limit)
Type: Primary Limit / Overheat Safety Switch
Function: Burner cutout on over-temperature
Equipment: Gas Furnace (80% AFUE)
Fits Model: GMV80704BXBA
Brand: Goodman (OEM)

OEM vs. Generic

The limit switch is a safety control calibrated to a specific setpoint and mounting geometry. OEM ensures the correct 150°F rating, bracket, and terminal configuration for a true drop-in fit. Generic parts with the wrong setpoint can nuisance-trip or allow unsafe overheating. Choose OEM for reliable protection.

Install Difficulty

Easy (2/5). Remove the mounting screws and transfer the two wire terminals to the new switch. If the limit keeps tripping, correct the airflow restriction rather than bypassing the control. Always shut off gas and power before servicing.

Compatible with Goodman GMV80704BXBA furnaces. Verify temperature rating and part number before ordering.
