What it is
The Navien 30017321A is a fan assembly for the NCB-CE ERP range of gas boilers. It moves combustion air into the burner and carries flue products out through the flue system, and it forms part of the appliance's combustion circuit. It is used across both system and combination models in the NCB-CE ERP family.
Signs this part needs replacing
- The boiler locks out or fails to ignite, with a fan or air pressure related fault code shown
- Abnormal noise from the fan area, such as scraping, rumbling or a dry bearing whine
- The fan runs intermittently, slows, or does not spin at all when the appliance calls for heat
- Repeated lockouts after resetting, particularly where flue or air pressure faults return
- Visible damage, contamination or stiffness when the fan is turned by hand
Before you order
