Goodman B1370198 150°F Primary Limit Switch

The B1370198 is a genuine OEM 150°F primary high-limit switch for the Goodman GMV80905CXA gas furnace. Mounted on the heat exchanger bulkhead, it monitors supply-air temperature and shuts off the burners if the plenum overheats — typically from a dirty filter, closed registers, a failing blower, or restricted return air. Restoring the correct-rated limit prevents heat-exchanger damage and stops the furnace from short-cycling on over-temperature.

Trip temperature: 150°F
Function: Auto-reset primary high-limit safety switch
Fits model: Goodman GMV80905CXA (verify against your rating plate)
Type: OEM factory limit control
Brand: Goodman

OEM vs. Generic

The OEM B1370198 uses Goodman's exact 150°F set point, mounting flange, and terminal spacing, so it drops in without adapting the wiring. Generic limits with a different trip temperature can nuisance-trip or allow the exchanger to overheat. On a safety high-limit, match the factory part exactly.

Install Difficulty

Easy. Cut power at the breaker, disconnect the two terminals, remove the mounting screws, and swap in the new switch. If the new limit trips repeatedly, check airflow — filter, blower speed, and duct restrictions — before condemning the switch.
