Goodman B1370155 Auxiliary Limit Switch (120°F)

The B1370155 auxiliary limit switch is a genuine Goodman/Amana OEM safety limit rated at 120°F, engineered as a direct-fit replacement for the AMS80453AXAA gas furnace and compatible models. Typically mounted on the blower deck or near the cabinet, this auxiliary (secondary) limit monitors temperature in horizontal or restricted-airflow installations and shuts the furnace down if it detects overheating from a blocked filter, failed blower, or closed ductwork. It protects the heat exchanger and cabinet from heat damage.

Specifications

OEM Part Number: B1370155
Trip Temperature: 120°F
Component: Auxiliary / secondary high-limit safety switch
Fits Model: AMS80453AXAA (and compatible Goodman/Amana furnaces)
Reset: Automatic (resets on cool-down)

OEM vs. Generic

The OEM B1370155 is set to the precise 120°F trip point required for your furnace's orientation and airflow design. A generic switch with the wrong rating can either fail to protect the unit or cause frequent nuisance shutdowns. Use the OEM part to keep the safety circuit within spec.

Install Difficulty

Easy (2/5) — Turn off power, unplug the wire terminals, remove the mounting screws, and fit the replacement. If the limit trips repeatedly, check the air filter, blower operation, and duct restrictions before returning the furnace to service.
