The Goodman B1370253 Stack Overtemp Limit Switch is a genuine OEM temperature-sensing safety control for the GMPN100-4 gas furnace and compatible Goodman/Amana models. Mounted on the flue/stack, it senses excessive vent temperature and interrupts the control circuit to shut the furnace down before overheating causes damage. It is a small, inexpensive part that plays a critical role in safe furnace operation.

Specifications

OEM Part Number: B1370253
Type: Stack / vent overtemperature limit switch
Trip Temperature: 140°F
Reset: Automatic (SPST, opens on rise)
Terminals: 1/4" male quick-connect spade
Fits: Goodman GMPN100-4 furnace and cross-compatible models

OEM vs. Generic

The genuine OEM Goodman switch guarantees the correct 140°F setpoint and factory terminal layout for a plug-and-play swap. Aftermarket equivalents can carry the wrong trip temperature or a different mounting footprint, which may cause short-cycling or failure to protect the furnace. For safety controls, we recommend sticking with OEM.

Installation Difficulty

Easy (1 of 5) — Cut power to the furnace, disconnect the two wire leads, remove the mounting screws, and install the new switch in reverse. If the switch is tripping repeatedly, verify proper venting and airflow before assuming the part is bad. When in doubt, consult a licensed HVAC professional.
