Goodman B1370155 Auxiliary Limit Switch (120°F)

The Goodman B1370155 is a genuine OEM 120°F auxiliary limit switch designed for the AMH81155CNAB furnace and related Goodman/Amana models. This secondary high-limit control monitors temperature in the blower compartment or return air path and interrupts operation if heat builds beyond safe levels — typically from restricted airflow, a dirty filter, or a failed blower. It's a key layer of the furnace's overheat protection.

Specifications

Trip Temperature: 120°F
Type: Auxiliary / secondary high-limit switch
Reset: Automatic (temperature-sensing)
Compatibility: AMH81155CNAB and related Goodman/Amana furnaces
OEM Part Number: B1370155

OEM vs. Generic

The genuine OEM B1370155 is factory-calibrated to the exact 120°F set point this furnace requires. Aftermarket look-alikes with different trip temperatures cause nuisance shutdowns or fail to protect the equipment. For a reliable, correctly rated repair, install the OEM part.

Installation Difficulty

Easy (2/5). Cut power, unplug the two spade terminals, remove the mounting screws, and swap in the new switch. Roughly 15 minutes with a nut driver. Replace clogged filters and verify airflow to prevent repeat trips.
