The Goodman B1370155 Auxiliary Limit Switch is a genuine OEM 120°F temperature-limit safety control for the AMH80453ANAC gas furnace. The auxiliary limit protects the blower compartment by opening the circuit when it senses excessive heat — typically caused by restricted return airflow, a dirty filter, or a blower fault. It works alongside the primary high limit to keep furnace temperatures within safe bounds.

Trip temperature: 120°F
OEM part number: B1370155
Fits model: AMH80453ANAC (80% gas furnace)

OEM vs. Generic

The OEM B1370155 switch is set to the exact 120°F trip point specified for this furnace. Substituting a switch with a different rating can cause nuisance shutdowns or, worse, allow unsafe temperatures. As a safety control, it should always be replaced with the genuine factory part.

Installation Difficulty

Easy (2/5). Secured with two screws and spade terminals, the switch swaps out in minutes. Disconnect gas and power first, transfer the wires one at a time to avoid mix-ups, and mount the replacement in the original orientation. If the switch had tripped, correct the airflow restriction (check the filter and blower) before restarting the furnace.
