Goodman B1370155 Auxiliary Limit Switch (120°F)

The Goodman B1370155 is a genuine OEM auxiliary limit switch rated at 120°F. Typically mounted on the blower deck or near the cabinet, this control opens the circuit when blower-compartment temperatures climb too high — commonly due to a stuck blower or blocked return airflow — shutting down the burners to prevent overheating. It is a direct-fit replacement for the Goodman/Amana ADV80703BXBB gas furnace. Replacing a worn or tripped auxiliary limit restores proper high-temperature protection.

Specifications

Part number: B1370155
Trip temperature: 120°F
Type: Auxiliary / secondary limit switch
Function: Blower-compartment overheat safety cutoff
Compatible model: ADV80703BXBB furnace
Brand: Goodman / Amana

OEM vs. Generic

OEM auxiliary limits are calibrated to the exact 120°F set point and use the correct mounting profile so the sensor reads cabinet temperature accurately. Generic substitutes can trip early or late, causing nuisance shutdowns or missed protection. For a safety limit, genuine OEM is the right call.

Installation Difficulty

Easy — a 10–15 minute repair. Disconnect power, remove the two spade wires, unscrew the mounting bracket, and install the new switch. If the old switch tripped, verify blower operation and airflow before returning the furnace to service.
