The Goodman B1370155 Auxiliary Limit Switch is a genuine OEM 120°F overheat safety control for the Goodman ADV80905CXA gas furnace and compatible models. Typically mounted on the blower deck or near the secondary heat exchanger, this auxiliary limit opens the control circuit if temperatures exceed its setpoint — protecting the furnace from restricted airflow, a failed blower, or a clogged filter.

Specifications

Part Number: B1370155
Trip Temperature: 120°F (auxiliary/secondary limit)
Category: Limit Switch
Equipment Type: Gas Furnace
Fits Model: ADV80905CXA (and compatible ADV-series)
Function: Secondary overheat protection

OEM vs. Generic

This genuine Goodman OEM switch matches the precise 120°F setpoint and mounting footprint your furnace requires. Because it is a safety device, using a generic switch with an incorrect trip temperature can cause nuisance shutdowns or defeat overheat protection entirely. Always match the OEM rating.

Installation Difficulty

Rating: Easy (2/5). Unscrew the old switch, transfer the spade connectors, and mount the replacement in the same orientation. Cut power at the disconnect before servicing, and correct any airflow restriction that caused the trip.
