Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. Fan bearing noise does not immediately affect cooling performance or wine storage safety. The unit is safe to continue using while you arrange service. However, a worn bearing will eventually fail completely, stopping airflow and causing the column to warm — arrange service before the bearing fails fully rather than waiting.
Can I reset the code?
No. Fan bearing wear and ice buildup are physical conditions. A reset will not address either cause. Manual defrost can resolve ice-induced noise; bearing replacement requires service.
When to stop immediately?
Stop if you notice: Fan noise becomes a grinding or scraping sound rather than clicking or whining, One or both zones begin to warm above setpoint alongside the noise.
Symptoms You May Notice
A clicking or whining sound from inside the column during compressor-on cycles
A repetitive metallic clicking or a high-pitched whine that starts when the compressor starts and is consistent throughout the cooling cycle, then stops when the compressor switches off.
Noise is more prominent when the column door is opened
Opening the column door makes the fan noise clearly audible from inside the cabinet, particularly on quieter evenings in an open-plan kitchen.
Fan noise that worsens gradually over several months
The sound started as a faint intermittent tick and has become louder and more continuous over time, indicating progressive bearing wear rather than a one-time foreign-object intrusion.
Sound level increases as the cabinet cycles between defrost and cooling modes
The abnormal noise becomes more prominent at specific points in the operating cycle and is not present during quiet standby.
Possible Causes
Worn evaporator fan motor bearing
The bearing in the evaporator fan motor has worn and the fan shaft is wobbling slightly, producing a click on each rotation or a continuous whine as the bearing surfaces degrade.
Requires ProfessionalIce accumulation on the fan blade contacting the housing
A frost buildup on the evaporator coil or fan blade has created an imbalance or direct contact between the rotating blade and the surrounding housing, producing a rhythmic clicking sound.
DIY PossibleFan blade debris or foreign object
A small piece of foil, a label fragment, or other debris has become lodged near the fan blade and contacts it on each rotation.
DIY PossibleSafe Checks You Can Do

1
Perform a manual defrost to rule out ice-induced noise
Switch the dedicated circuit breaker off for eight hours with both doors propped slightly open and a towel at the base of the column. This forces a complete manual defrost. After eight hours, restore power and listen to the fan during the next cooling cycle. If the clicking or whining is gone, ice buildup was the cause.
Ice-induced fan noise on Designer columns most commonly occurs after unusually frequent door openings over a period of days — for example, during a party or extended entertaining. A manual defrost often resolves it completely without service.

Listen carefully to characterize the noise
Note whether the noise is rhythmic at a rate consistent with the fan rotation speed (bearing or blade contact), or more irregular (debris). Also note whether it is present from the first second the compressor starts or only develops after the fan has been running for several minutes.
A noise that is present immediately from startup and worsens progressively over months is almost always bearing wear. A noise that clears after a manual defrost was ice. Knowing this before the technician arrives accelerates the diagnosis.
When to Call a Professional
Contact a qualified technician if:
- Fan noise persists after a complete eight-hour manual defrost
- Noise is a continuous grinding quality indicating advanced bearing failure
- Zone temperatures are rising alongside the fan noise
