The genuine OEM Lennox 67K32 pressure switch, supplied complete with its mounting bracket, is a safety control that confirms proper airflow and venting before your Lennox furnace is allowed to ignite. It senses the negative pressure created by the inducer motor and only closes to permit the ignition sequence when adequate draft is verified, protecting your home from unsafe combustion conditions.

A failing or tripped pressure switch commonly causes the furnace to lock out on ignition, short cycle, or fail to fire at all. You may notice the inducer running without the burners lighting, repeated fault codes, or a switch that stays stuck open or closed. Blocked vents, cracked hoses, or a worn diaphragm can all contribute.

Installing the OEM Lennox 67K32 ensures the exact pressure set point, port configuration, and bracket fit your furnace was engineered for. Non-OEM switches with different trip pressures can cause nuisance lockouts or, worse, bypass a genuine safety condition. This factory part restores safe, reliable ignition.

To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Lennox pressure switch?
