Description

Original NoFrost cooling fan for Liebherr refrigerator-freezer 7413364

Original Liebherr NoFrost fan, part number 7413364, is designed for CNG and CNS series refrigerator-freezers. The part restores uniform air flow in the refrigerator and freezer compartments, stops frost buildup and keeps DuoCooling and NoFrost technologies in full operation. Fits models CNgbc 5723 and CNSDC 5723. Original Liebherr part only.

Is the refrigerator not cooling properly? Is the cooling uneven? The fan may have stopped. When the fan is not spinning, the compressor continues to work but the cold air does not reach all parts of the refrigerator. Food starts to spoil sooner, frost builds up in the freezer compartment, and an error code may appear on the display. Check compatibility with your model before ordering.

Why does the Liebherr fan stop working?

The NoFrost fan is a mechanical component that works continuously. In the experience of our technicians, most failures occur after 7-10 years of use – whether due to natural wear of the built-in motor, ice buildup blocking the fan blades, or electrical failure due to unstable voltage. The fan is the heart of the NoFrost system: without its movement, all the other technology – DuoCooling, EasyFresh – cannot function properly.

A genuine part ensures that the fan will fit exactly into the original rails and connectors. Non-genuine parts may run at the wrong speed and affect temperature control.

Important: This list includes only verified models. Before ordering, verify the part number against the model sticker (E-Nr) located on the inside wall of the refrigerator compartment.

🔧 How do you replace the NoFrost fan?

Replacement is rated Pro – requires a certified technician. Accessing the fan requires dismantling an internal panel at the back of the freezer compartment, disconnecting electrical connectors, and precise assembly that affects airflow balance. An installation error could lead to uneven cooling or damage to other components.

⚠️ Before any work – completely unplug the refrigerator.

Replacement steps (for technician):

1. Empty the freezer compartment and store food in a cool place outside.
2. Remove the inner back panel in the freezer compartment (Phillips screws)
3. Locate the fan housing and disconnect the electrical connector.
4. Release the retaining clips and remove the old fan.
5. Insert the new fan and secure the clips.
6. Connect the electrical connector and assemble the back panel.
7. Turn on the refrigerator and check for proper operation after 2-3 hours.

💡 Tip from the experts

Before ordering a part – check the filter. From our field experience, in about 25% of cases where the customer thought the fan was broken, we found that the problem was ice buildup blocking the fan blades. A complete manual defrost of the device (about 24 hours) solved the problem without the need to replace parts. If after defrosting the fan is still quiet – the part is in the right direction.

Based on numerous service visits, fan failure is one of the 3 most common reasons for no cooling in NoFrost refrigerators, after compressor failures and temperature sensor problems.

❓ Frequently Asked Questions

How do I know if my fan is broken?

Open the freezer door and check for noise from the motor. A working fan will produce a gentle stream of air that you can feel with your hand. If there is complete silence while the compressor is running, the fan may have stopped working. Other symptoms include uneven temperatures between shelves, abnormal frost buildup in the freezer, and food spoiling more quickly than usual.

Will a non-original replacement fan work just as well?

Not necessarily. A genuine Liebherr fan is calibrated to a rotation speed and air output that matches the DuoCooling control logic. An unapproved part may run at a different speed – which will result in uneven cooling, higher power consumption, and sometimes errors in the digital display.

How long can inaccurate calibration cause further damage?

A refrigerator that is operating without a proper fan puts a strain on the compressor. The compressor tries to compensate for the high temperature and works longer hours, which significantly shortens its service life. Our technicians have seen cases where a delay of weeks in servicing led to a compressor failure that cost 5-8 times more to repair than replacing a fan.
