Frequently Asked Questions
Is this fan compatible with the Viessmann Vitodens 100 WB1A?
Yes. Viessmann fan 7823839 is compatible with the confirmed Vitodens 100 and Vitodens 100W WB1A models listed above. Check the complete boiler model and existing part number before ordering.
How can I confirm that Viessmann 7823839 is the correct replacement fan?
Check the manufacturer part number on the existing fan or the appliance parts information and compare it with 7823839. You should also confirm the boiler model, version, output and fuel type.
What does the RG130 radial fan do inside the boiler?
The radial fan moves air through the boiler to support combustion and helps direct combustion gases through the flue system. Correct fan operation is important for the boiler’s ignition and safe running sequence.
What symptoms may indicate a problem with the boiler fan?
Possible symptoms can include ignition failure, unusual fan noise, intermittent operation or the boiler entering a fault condition. These symptoms do not confirm that the fan is defective, so the appliance should be professionally diagnosed before replacing the component.
Does this Viessmann fan require professional installation?
