Goodman B1370155 Auxiliary Limit Switch — 120°F

The Goodman B1370155 is a genuine OEM auxiliary limit switch rated at 120°F, built for the Goodman DDS80703AXA gas furnace and compatible models. Located in the blower compartment, this backup high-limit safety opens the control circuit if temperatures climb too high due to restricted airflow, a dirty filter, or blower failure. It protects the furnace from overheating when the primary limit does not respond, preventing heat-exchanger damage and nuisance lockouts.

Specifications

Trip temperature: 120°F (open on rise, auto-reset)
Type: Auxiliary / backup high-limit switch
Function: Blower-compartment over-temperature protection
Terminals: Standard 1/4 in male spade
Fits: Goodman DDS80703AXA furnace
OEM Part Number: B1370155

OEM vs. Generic

The OEM Goodman B1370155 is factory-calibrated to the precise 120°F trip point for dependable secondary protection. A generic 120°F auxiliary limit may cost less — confirm the exact trip temperature, mounting bracket, and terminal type, as accurate calibration is essential for a safety device.

Installation Difficulty

Easy (2/5). Unscrew the switch from its bracket, move the two wire connectors, and remount — roughly 15 minutes with a screwdriver. Disconnect power before servicing. If this switch trips often, check the air filter and blower operation, and have persistent overheating diagnosed by a licensed HVAC technician.
