Goodman B1370155 Auxiliary Limit Switch (120°F)

The B1370155 is a genuine Goodman/Amana auxiliary high-limit switch engineered as a direct-fit replacement for the AMH80453ANAA gas furnace. This normally-closed thermal safety control opens the ignition circuit if it senses excessive heat near the blower compartment, shutting the burners down before damage or a hazard can occur. A failed or nuisance-tripping auxiliary limit is a common cause of a furnace that starts, runs briefly, then stops on a safety lockout.

Specifications

Trip point: 120°F (auxiliary limit)
Type: Normally-closed automatic-reset thermal switch
Fit: Goodman / Amana AMH80453ANAA furnace
OEM part number: B1370155
Function: Blower-compartment over-temperature protection

OEM vs. Generic

Our OEM option is the exact Goodman-specified switch with a factory-calibrated 120°F trip point and matching terminal geometry for a plug-and-play install. A Generic equivalent meets the same electrical rating at a lower price point but may require minor bracket adjustment. For a safety-critical limit control we recommend OEM to guarantee the correct calibration.

Install Difficulty: Easy

Rated Easy (1 of 5). Shut off power and gas, disconnect the two spade terminals, remove the mounting screws, and swap in the new switch — typically a 10–15 minute job for a homeowner comfortable working inside the furnace cabinet. Always confirm power is off at the breaker before servicing.
