Goodman B1370190 Primary Limit Switch (210°F)

The B1370190 is a genuine OEM 210°F primary high-limit switch for the Goodman/Amana AMH80453ANAB furnace. Positioned on the heat exchanger side of the furnace, the primary limit monitors supply-air temperature and cuts power to the gas valve if the furnace overheats — most commonly from restricted airflow caused by a clogged filter, closed registers, or a weak blower. It is the furnace's main line of defense against heat-exchanger damage and fire risk.

Specifications

Trip temperature: 210°F
Type: auto-reset primary high-limit switch
Fits: Goodman/Amana AMH80453ANAB furnace
OEM part number: B1370190

OEM vs. Generic

Our OEM limit is calibrated to Goodman's exact 210°F set point and uses the correct insertion depth and bracket for this furnace. Generic switches with different trip points can trigger frequent lockouts or allow unsafe temperatures — not worth the small savings on a safety part.

Installation Difficulty

Easy — unplug the wire connectors, remove two screws, and mount the new switch in the same location and orientation. Roughly 15 minutes with power off. If it keeps tripping, correct the airflow restriction before re-running the furnace.
