Neff B12S22N3GB/01 Cooker Oven Main Fan Not Spinning

Hi Gary,

Thank you for providing those details for the Neff B12S22N3GB/01 Cooker Oven.

I've reviewed the information you've sent over, and I'm confident we can help you resolve this issue.

Finding the Part Number

The first step is to locate the part number on your fan motor. I've included the manufacturer's PDF diagrams of the oven to guide you through the disassembly process. Since your Neff B12S22N3GB/01 is only eight years old, we should have the correct replacement part in stock or be able to source it quickly once we have that number.

Checking the Motor Voltage

Once you've accessed the motor, please turn the oven on in fan mode and use a multimeter to check the voltage at the motor wires. In the UK, you should read 240 volts. This will confirm whether the motor is receiving power or if there's an electrical fault upstream.

Removing the Fan Blade Safely

When you're ready to remove the fan blade, remember that the retaining nut has a reverse thread. Turn it clockwise to loosen it — this is the opposite of standard fasteners, so take care not to force it the wrong way. Some screws may be tight due to heat exposure over the years, so use a screwdriver that fits the slot properly to avoid stripping them.

Getting the Right Part

Once you've found the part number, you can contact us through the Contact Us page and select "Parts" from the category dropdown rather than "Technical Help". If the part isn't listed in our current catalogue, we can add it and arrange supply for you.

My contact details will be included in the email confirmation you receive. I've also attached a video walkthrough that should help clarify the process.
