The Goodman B1370155 auxiliary limit switch is a genuine OEM 120°F auto-reset safety control for the AMS80453AXA gas furnace and compatible Goodman/Amana models. Typically mounted near the blower compartment, this secondary limit guards against overheating from restricted airflow — a dirty filter, blocked returns, or a failing blower. When cabinet temperature exceeds the set point it interrupts the control circuit to prevent heat damage.

Trip temperature: 120°F open

OEM vs. Generic

The OEM Goodman B1370155 is factory-calibrated to the correct 120°F set point and body style for a proper fit and reliable overheat protection. Generic replacements can vary in trip point and mounting, causing premature cycling or inadequate protection. For a safety control, OEM accuracy matters.

Installation Difficulty: Easy

Unscrew the old switch, move the two spade connectors, and mount the new one in the same orientation. A straightforward job for homeowners with power off at the disconnect. If the limit was tripping, correct the airflow restriction — replace the filter and check the blower — before restarting the furnace.

Genuine Goodman OEM auxiliary limit — the correct factory-specified safety part.
