What it is
The fan assembly for Navien LCB 700 series boilers, supplied under part number 30021328A. It moves combustion air into the burner and carries flue products out of the appliance, so it sits at the centre of the boiler's combustion and flue path. The LCB 700 range covers combi, regular and system boilers in 36KW output, in both internal and external variants.
Signs this part needs replacing
- Boiler locks out or fails to ignite, with a fan or air pressure related fault code logged
- Fan noisy in operation — rumbling, scraping or bearing whine that changes with fan speed
- Fan does not spin up on a call for heat, or spins intermittently
- Repeated lockouts shortly after ignition that clear on reset
- Visible damage, contamination or stiffness when the fan is turned by hand
Before you order
- Confirm the boiler model and variant against the fit list above, as LCB 700 combi, regular and system models differ
- Check the existing fan assembly part number on the appliance before ordering
- Inspect the flue and air intake paths for blockage or debris, as these can mimic fan failure
- Confirm the appliance is isolated from gas and power before any work begins
