What it is
The Navien fan assembly, part number 30017324A, is the combustion air fan unit used on Navien NCB-CE ERP boilers. It draws air into the combustion chamber and drives flue gases out through the flue system. It is a serviceable component on both system and combination models in this range.
Signs this part needs replacing
- Boiler locks out or fails to fire, with a fan-related fault code logged
- Fan runs noisily, with whining, grinding or rumbling from worn bearings
- Fan does not spin up on a call for heat, or spins intermittently
- Repeated ignition failures or flame loss shortly after start-up
- Overheat or flue-related lockouts traced to reduced air movement
