Goodman B1370198 Primary Limit Switch (150°F)

The Goodman B1370198 is a genuine OEM primary high-limit switch rated at 150°F, engineered as a direct-fit safety control for the GMV80905CXBA gas furnace. Located on the heat exchanger/blower deck, this limit monitors supply-air temperature and shuts off the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or a failing blower. It protects the heat exchanger from cracking and prevents dangerous overheating.

Specifications

OEM Part Number: B1370198
Trip Temperature: 150°F (opens on rise)
Type: Primary / high-limit temperature switch
Function: Over-temperature heat exchanger protection
Fits Model: GMV80905CXBA and compatible Goodman/Amana furnaces
Equipment: Gas Furnace

OEM vs. Generic

The genuine Goodman limit is factory-calibrated to open at exactly 150°F and includes the correct mounting flange and insertion depth for accurate sensing. Generic limits with the wrong trip point or probe length can cause short-cycling or fail to protect the exchanger. For a safety control, OEM accuracy is essential.

Install Difficulty

Easy (2 of 5). Two mounting screws and two spade connectors, roughly 15–20 minutes. Power down the furnace before servicing. If the new limit trips, correct the airflow restriction (filter, blower, ductwork) rather than repeatedly resetting it.
