What it is
The Navien fan assembly, part number 30022170A, is the combustion fan unit used on Navien NCB300 and NCB500 series combi boilers. It moves the air and flue gas through the combustion circuit under the control of the boiler's PCB. The assembly is supplied as a complete fan unit for the appliance models listed below.
Signs this part needs replacing
- Boiler locks out or fails to ignite with a fan-related fault code logged
- Fan noisy in operation, with rumbling, scraping or bearing whine
- Fan not running at all when the boiler calls for heat
- Repeated flame failure or unstable combustion during demand
- Visible damage, contamination or stiffness when the fan is turned by hand
Before you order
- Confirm the model and serial number on the boiler data badge match one of the fitments listed
- Check the fault code and fan operation at the boiler before condemning the assembly
- Inspect the flue, air inlet and condensate routes, as blockages can mimic fan failure
- Confirm the part number 30022170A against the existing fan unit where it is legible
