What it is

The N310-0504005 is a combustion fan assembly manufactured by Johnson & Starley for the Economaire range of gas boilers. It moves the products of combustion through the appliance and out to the flue, maintaining correct draught across the heat exchanger. The assembly is supplied as a complete fan unit for the Economaire 31 and Economaire 32.

Signs this part needs replacing

  • Fan noisy in operation, with rumbling, scraping or bearing whine
  • Fan fails to start or runs intermittently when the boiler is called for heat
  • Boiler locks out or fails to fire, with the fan proving sequence not completing
  • Overheat thermostat tripping or repeated resetting during normal running
  • Visible damage, contamination or stiffness when the fan is rotated by hand

Before you order

  • Confirm the appliance model is an Economaire 31 or Economaire 32
  • Check the existing fan assembly against part number N310-0504005
  • Verify the fault is with the fan and not the air pressure switch, wiring or control board
  • Isolate the electrical supply and gas before removing the existing assembly
