What it is

The air flap with frame is a Viessmann casing component for Vitodens WB3A gas boilers, listed under part number 7823950. It fits the 26kW and 35kW models built from 02.06.2005 and forms part of the combustion air path on the appliance.

Signs this part needs replacing

  • The flap no longer seats squarely in its frame, leaving a visible gap
  • The frame is cracked, distorted or has broken mounting points
  • The flap sticks or fails to move freely through its travel
  • Combustion readings drift or the appliance shows unstable operation linked to the air path
  • Heat damage, warping or debris build-up on the flap or frame

Before you order

  • Confirm the appliance model is a Vitodens WB3A in 26kW or 35kW output
  • Check the appliance was manufactured from 02.06.2005 onwards
  • Verify the existing part number 7823950 against the component being replaced
  • Inspect the surrounding casing and seals for related damage before fitting
