Product Details

The Lennox 34M76 is a single-pole single-throw (SPST) pressure switch designed for use in Lennox HVAC systems. This pressure switch activates at 0.86 inches water column (WC), providing reliable pressure sensing for furnace and heating equipment operation.

Key Features:

  • Pressure activation point: 0.86 inches water column
  • SPST (single-pole single-throw) switching configuration
  • Genuine Lennox OEM replacement part
  • Designed for furnace draft pressure monitoring
  • Ensures safe operation by verifying proper venting pressure

This pressure switch is a critical safety component that monitors draft pressure in gas furnaces, helping to ensure proper combustion and venting. When the pressure reaches the setpoint, the switch closes to allow the heating system to continue its ignition sequence.

I saw in a big box store something I wanted but got sticker shock with the price. Boatplicity had the extract same thing for 20% less. It was delivered to my home in a very speedy manner and was very well packed so it was in pristine condition. I will use this site again!
