The Goodman B1370155 Auxiliary Limit Switch is a genuine OEM temperature control designed for the Amana/Goodman AMS80453ANAA gas furnace. Mounted on the blower housing, this 120°F auxiliary limit protects the blower compartment and motor from excessive heat, shutting down the burner if airflow is lost or the compartment overheats.

Trip Temperature: 120°F
Reset Type: Automatic
Function: Blower-compartment auxiliary high limit
Fits Model: AMS80453ANAA
Terminals: 1/4" quick-connect spade
OEM Part #: B1370155

OEM vs. Generic: The genuine Goodman OEM auxiliary limit is factory-set to the precise 120°F cut-out required by this furnace's design. Aftermarket substitutes often use approximate trip points that don't match the blower cabinet's thermal profile, leading to short cycling or inadequate protection. Choose OEM for correct fit and reliable safety response.

Install Difficulty: Easy (1/5). Disconnect power, note the wire positions, unplug the spade terminals, remove the mounting bracket screws, install the new switch, and reconnect. Most homeowners complete this in 10–15 minutes. Confirm normal heating and blower operation afterward.
