The genuine Goodman B1392633 is a 14-inch vent motor gasket engineered as the factory sealing component for the induced-draft (vent) motor assembly on GMTH070-4 gas furnaces and compatible Goodman/Amana models. This gasket sits between the vent motor housing and the flue collector, creating an airtight seal that prevents flue-gas leakage and maintains the correct negative pressure the pressure switch relies on to prove draft.

Specifications

OEM Part Number: B1392633
Type: Vent (induced-draft) motor gasket
Nominal size: 14 inch
Material: High-temperature furnace-grade gasket material
Fits: Goodman GMTH070-4 and compatible furnace platforms
Brand: Goodman (OEM)

OEM vs. Generic

The OEM Goodman gasket is die-cut to the exact bolt pattern and temperature rating of the vent motor flange, guaranteeing a leak-free seal and preserving your equipment warranty. Universal aftermarket gaskets often require trimming and may not hold the same high-temperature tolerance, risking flue leaks and nuisance pressure-switch faults. For a safety-critical combustion seal, OEM is strongly recommended.

Installation Difficulty

Easy (1/5) — Replaced during vent motor service. Shut off power and gas, remove the vent motor mounting screws, peel off the old gasket, clean the flange, and seat the new B1392633 before reinstalling. A qualified HVAC technician should verify draft and combustion after any flue-component service.

Always de-energize the furnace at the disconnect before servicing. If you are unsure of compatibility, contact us with your full model and serial number.
