The Goodman B1370190 Primary Limit Switch is the genuine OEM high-limit safety control for the ADV81155CXA gas furnace and related Goodman/Amana models. Rated to open at 210°F, it mounts on the heat-exchanger/plenum area and de-energizes the gas valve if supply-air temperature climbs too high — the furnace's main line of defense against a blocked blower, dirty filter, or restricted ductwork.

Specifications

Part Number: B1370190
Function: Primary high-limit protection
Trip Temperature: 210°F (open on rise)
Brand: Goodman OEM
Equipment: Gas furnace
Primary Fit: ADV81155CXA

OEM vs. Generic

The primary limit is a life-safety device tuned to your furnace's specific heat-exchanger geometry and airflow. The OEM B1370190 delivers the exact 210°F set point and bracket the unit expects. Generic replacements with approximate ratings risk premature lockouts or delayed shutdowns; for a component that prevents overheating, match factory spec.

Installation Difficulty

Easy (1/5). Remove two mounting screws, transfer the spade connectors, and reinstall — about 10 minutes. Cut power and gas first, and verify airflow issues (filter, blower) are resolved so the new limit isn't tripped by an underlying fault.
