The Goodman B1370155 is a genuine OEM 120°F auxiliary limit switch designed as a direct-fit replacement for the GMNTE120-5 gas furnace. The auxiliary limit is a secondary overheat safety mounted on the blower housing or near the heat exchanger. If airflow drops — from a clogged filter, failed blower, or blocked ductwork — cabinet temperatures climb and the 120°F switch opens to shut down the burners before heat damages the furnace.

Trip point: 120°F open temperature
Reset: Auto reset (closes on cool-down)
Type: Normally-closed auxiliary/backup limit switch
Fits: Goodman GMNTE120-5 furnace
Connection: 1/4 in quick-connect terminals

OEM vs. Generic: This genuine Goodman control is calibrated to the exact 120°F set point and bracket geometry the furnace requires. Aftermarket equivalents can differ in trip temperature or differential, causing short-cycling or delayed protection. For consistent, safe operation the OEM part is the reliable choice.

Install difficulty: Easy. Cut power to the furnace, unplug the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. If the auxiliary limit keeps tripping, check the filter, blower, and ductwork for restricted airflow before restarting.
