What it is

The air pressure sensor is a Navien component used on LCB 700 series boilers. It monitors air pressure within the combustion air circuit and provides a signal to the boiler's control system. It is fitted across the LCB 700 combi, regular and system ranges in 21KW, 28KW and 36KW outputs, in both internal and external variants.

Signs this part needs replacing

  • Boiler locks out or fails to fire, with an air pressure or fan-related fault code logged
  • Fan runs but the boiler does not prove air flow and shuts down
  • Intermittent lockouts that clear on reset and return during demand
  • Boiler starts, then cuts out shortly after ignition
  • Fault code relating to the air pressure switch or sensor persists after checking the flue and fan

Before you order

  • Confirm the boiler model and output against the fit list above
  • Check the part number on the existing sensor matches 30022962B
  • Inspect the sensing tubes and connections for blockage or damage before replacing the sensor
  • Confirm whether the appliance is the internal or external variant
