Lennox 81L93 Inducer Gasket
The Lennox 81L93 Inducer Gasket (also cataloged as 81L9301) is a critical genuine OEM replacement part engineered to maintain the pressure boundary between the draft inducer motor and the combustion blower housing. Constructed from premium fiberglass heat-resistant material, this 6.5" x 6.5" white gasket is designed to withstand the high-temperature flue gases typical of 80% and 90%+ AFUE residential furnaces. A compromised seal at the inducer can lead to static pressure drops, triggering furnace pressure switch lockout codes and leaking combustion byproducts into the cabinet. This high-density Lennox furnace seal ensures a precise fit for Armstrong, Concord, Ducane, and Lennox G40UH and G50UH series units. For technicians performing HVAC inducer motor replacement, swapping this gasket is mandatory to ensure a localized airtight combustion seal and prevent premature component failure due to vibration or gas leakage.
Key Benefits for the Jobsite:- Direct OEM Compatibility: Verified fit for multiple brands including Allied, Magic-Pak, and Lennox G60UH series, replacing both 81L93 and 81L9301.
- Fiberglass Construction: High-grade material prevents thermal degradation and maintains elasticity under high-cycle demand.
- Vibration Dampening: Minimizes mechanical resonance between the motor housing and the heat exchanger, contributing to quieter system operation.
- Airtight Integrity: Maintains the necessary negative pressure required for the furnace to successfully complete its ignition sequence.
Is this gasket compatible with the Fasco A200 inducer motor?
Yes, this is the standard interface gasket for the Fasco A200 series motors used across many Lennox furnace models.
Do I need to apply RTV silicone to this fiberglass gasket?
No, this Lennox 81L93 gasket is designed for dry installation. Adding sealant can interfere with the physical compression required for a proper seal.
Why is my furnace giving a 'Pressure Switch Stuck Open' code after motor service?
If the inducer gasket was reused or misaligned during reassembly, air leaks will prevent the vacuum required to close the pressure switch. Replacing the seal often resolves this.
