Original Liebherr refrigerator/freezer solenoid valve 909727900

Original Liebherr double solenoid valve (Magnetventil), responsible for distributing the cold between the refrigerator compartment and the freezer compartment. When the valve is faulty, one compartment remains cold and the other heats up. Manufacturer Part Number 909727900, original part only, not an unapproved replacement.

How does the solenoid valve work in a Liebherr refrigerator?

The valve is a small electric tap that opens and closes as needed, determining whether the cold reaches only the freezer or also the refrigerator. This way, Liebherr gives each compartment its own temperature, without the need for two separate cooling mechanisms.

When the valve gets stuck or breaks down, one chamber loses its cooling completely, even if the other chamber continues to work normally as if everything is fine.

What fault indicates a faulty solenoid valve?

The most typical sign is one compartment heating up while the other compartment remains cold. If the freezer continues to freeze properly but the refrigerator rises in temperature (or vice versa), this points directly to the valve or wiring that feeds it. Two field diagnostics that help narrow down the search:

Listen for a gentle click from the valve (located on the back of the appliance, near the compressor) as you turn the refrigerator compartment on and off. If there is no audible click, it is likely that the coil is not receiving power or that the internal mechanics have jammed. If the click is heard but the compartment still does not cool, check the coil wiring and the integrity of the thermistors before deciding that the problem is with the valve itself.

🔧 How do you replace a solenoid valve in a Liebherr refrigerator?

The valve is located on the back of the device, near the compressor, and is connected directly to the closed refrigeration circuit. This is not a DIY replacement : opening the refrigeration circuit requires emptying and refilling the refrigerant gas, professional tools, and a license to work with refrigerant gases. Independent performance may cause refrigerant leakage, irreversible damage to the system, or tampering with the device.

It is recommended that you call a qualified technician for repair. If you order the original part in advance and prepare it before the technician's visit, you save waiting time and a second trip, and minimize the time the device is down.

💡 Tip from the experts

According to Daniel, Plrom refrigeration expert, before replacing a solenoid valve, it is worth checking the coil resistance with an ohmmeter to make sure the problem is not due to broken wiring or a loose connection to the control board. A healthy coil will display a stable resistance value; an infinite or zero reading almost always indicates a burned coil that requires replacing the entire valve.

❓ Frequently Asked Questions

Why is the refrigerator cold but the freezer warm, or vice versa?

This is the classic sign of a faulty solenoid valve. The valve is responsible for routing the cold between the two compartments, and when it is stuck in one position, only one compartment receives cooling. The characteristic click of the valve during on and off should be checked before making a final diagnosis.

Can I replace the valve myself?

Not recommended. The valve is connected to a closed refrigeration circuit with pressurized refrigerant gas, and opening it requires professional draining and refilling. Independent replacement may cause gas leakage and irreversible damage to the refrigeration system.

Are SKU 909727900 and 9097279 the same part?

Yes, both numbers refer to the same 2x7W dual solenoid valve. 909761200 is also the same original product with another number, so if you come across one of these numbers on the device sticker, this is the correct part.
