The Goodman B1370253 Stack Overtemp Switch is a genuine OEM 140°F limit control for GMPN040-3 gas furnaces. Mounted on the vent/flue stack, it monitors flue temperature and interrupts furnace operation if the draft or venting system overheats — a common protection against blocked vents, inducer failures, and improper draft that could allow flue-gas spillage.

Specifications

OEM Part Number: B1370253
Type: Stack / flue overtemp limit switch
Trip Temperature: 140°F (open on rise)
Function: Normally closed, opens on overtemp
Fits: Goodman GMPN040-3 gas furnace
Brand: Goodman / Amana (Daikin)

OEM vs. Generic

Goodman OEM ensures the exact 140°F calibration and mounting footprint your furnace's flue assembly requires. Generic substitutes with mismatched trip points can cause nuisance shutdowns or, worse, fail to catch a venting fault. For a flue-safety device, the OEM part is the reliable choice.

Installation Difficulty

Easy (2/5). Mounts with existing screws and connects via spade terminals. Cut power to the furnace first. If the new switch trips, verify the flue is clear and the inducer draft is correct before returning the unit to service.
