ᐅ Replacing a Door Magnet for a BILLY Shelf – How Do I Find the Right Replacement Part?

Hello everyone,

I recently tried to repair the door on my BILLY bookshelf that uses a magnetic catch, but the door magnet has stopped working properly and no longer holds. Now I’m wondering: how can I find the right replacement part for the door magnet on the BILLY bookshelf?

Is there an official part number from IKEA that I can order directly, or should I rather rely on universal magnetic catches from a hardware store? It’s also important for me to know how to ensure that the replacement magnet is mechanically compatible and has the right holding force to avoid problems when closing the door.

If anyone has already replaced this part, I would appreciate tips on how to disassemble and install the magnet – sometimes I struggle with small details.

Thanks in advance for your help!

This is a more complex issue than it might seem at first. Unfortunately, IKEA rarely provides detailed part numbers for individual components like the door magnet. The first step is to identify the exact product number of your BILLY shelving unit—such as 002.638.50 or something similar—as this helps with identification.

Regarding the replacement part: it depends on whether you want the original magnet or a compatible alternative. Original parts are best ordered through IKEA customer service or directly at the store, often only with proof of purchase or a receipt showing the purchase date.

If you decide to use a universal part from a hardware store, be sure to check the technical specifications carefully: the strength of the magnet (usually indicated in Gauss), the size of the housing, and the mounting method (screws or adhesive). A magnet that is too weak will cause the door not to close properly, while one that is too strong can damage the door or affect the latch.

When removing the magnet: it is usually housed in a small recess in the door or the frame and is often secured with screws. Sometimes there is a plastic or metal insert underneath, which should be removed carefully during disassembly. Be careful not to damage the surrounding wood.

Could you specify which BILLY model you have and how the magnet is currently attached? Then I can provide more detailed instructions.

To add: IKEA usually does not offer individual replacement parts for the door magnet of the BILLY bookcase openly in their online shop. The replacement part is typically obtained through the customer service hotline or by visiting a store, where the availability of the magnet as a spare part can be checked using the product’s serial number.

Universal door magnets from a hardware store can be a cost-effective alternative if you pay attention to the correct dimensions: standard sizes of 15x15x5 mm (0.6x0.6x0.2 inches) or similar. You should also consider the holding force, which can empirically range between 1–3 kg (2.2–6.6 lbs) to ensure adequate adhesion.

I recommend inspecting the original magnet mounting before purchasing. Some BILLY models use recessed magnets housed in a cap, while others have simple clamp fittings. Taking precise measurements of the magnet housing and the mounting holes is essential.

In summary:
- Identify the serial number and model
- Contact IKEA customer service to request the original part
- Otherwise, take exact measurements and choose a hardware store magnet accordingly

As a precaution, check the IKEA installation manual, which is available online as a PDF, where such components are often described.

I would like to add to this question by pointing out that older BILLY shelves can vary depending on the year of manufacture, especially regarding the door magnets. Older models sometimes use different mounting systems or have larger magnets installed.

If you are unsure, you can carefully remove the magnet and measure it. A tape measure or caliper will help you note the important dimensions (length, width, height). Also, pay attention to the shape—rectangular, round, or with special cutouts. This will make finding a replacement part much easier.

I personally had to replace the magnet on a BILLY door hinge two years ago and was able to obtain the replacement part number from IKEA customer service by providing the model number and a photo of the magnet (at the time, they asked me to send it by email).

If you don’t have any luck with IKEA, you can also use technical magnets from a hardware store, usually found in the "furniture or door magnets" section.

If you like, I can also provide you with step-by-step instructions on how to remove the magnet and correctly install the new one.

For original spare parts, it is best to inquire directly at the IKEA service center.

Alternatively, look for a universal furniture magnet with similar dimensions.

Remove the magnet and measure its length, width, and thickness.

Install the new magnet with appropriate screws or adhesive.

Make sure the new magnet is strong enough; otherwise, the door will not close properly.
