The Goodman B1370187 Primary Limit Switch is a genuine OEM 160°F automatic-reset high-limit control for the Amana/Goodman AMH80703ANAC gas furnace. Mounted on the heat-exchanger partition, the primary limit is the furnace's main overheat protector: it opens the heating circuit and shuts down the burners if supply-air temperature climbs past the safe threshold, guarding the heat exchanger against cracking. A furnace that heats briefly then shuts off, or short-cycles on the limit, often needs this part.

Trip temperature: 160°F (opens on rise)
Reset type: Automatic reset
Function: Primary high-limit safety control
Fit: Goodman/Amana AMH80703ANAC and compatible furnaces
Terminals: 1/4 in. quick-connect spade

OEM vs. Generic: Genuine OEM B1370187 is set to the exact 160°F cutout and insertion-depth your furnace requires. A generic limit with the wrong trip point or probe length can cause chronic short-cycling or fail to protect the heat exchanger. For this core safety part, OEM is strongly recommended.

Installation difficulty: Easy — two mounting screws and two spade terminals, about 15 minutes. Always cut power before servicing and verify airflow (filter, blower, ducts) if the limit was tripping.
