What it is

The Navien premix blower fan assembly, part number 30017199A, is the combustion air fan used on Navien NCB-CE ERP boilers. It draws the air and gas premix into the burner and maintains the correct combustion airflow across the firing range. It is a serviceable component on the NCB-CE system and combination boiler range.

Signs this part needs replacing

  • Boiler locks out or fails to fire, with a fan or airflow related fault showing on the display
  • Grinding, scraping or whining noise from the fan area during or after ignition
  • Fan runs intermittently, at erratic speed, or not at all when the boiler is called for heat
  • Weak, unstable or repeatedly extinguishing flame caused by incorrect combustion airflow
  • Visible damage, play in the fan bearing, or contamination on the impeller

Before you order

  • Confirm the appliance is a Navien NCB-CE ERP model and check the serial number against the fitment list
  • Check the part number on the existing blower matches 30017199A
  • Confirm whether the boiler is the system or combination variant and its kW rating
  • Inspect the flue, air intake and combustion chamber for blockages before assuming the fan has failed
