Problem summary
Your Beko fridge freezer is no longer cooling the fresh food or freezer compartments, and you've noticed the fan motor running noisily all the time. This combination often points to a fault in the cooling system rather than a simple setting issue.
Likely causes
Based on repair patterns for this fault, the most common culprits are:
Control board (PCB) failure — The printed circuit board manages compressor operation and temperature control. If it fails, the compressor may not run at all, or run erratically. A noisy fan combined with no cooling suggests the control board isn't managing the system properly.
Evaporator fault — The evaporator is a sealed component that circulates refrigerant through the fridge compartment. If it leaks or becomes blocked, cooling stops. This is part of the refrigeration circuit and cannot be repaired at home.
Temperature sensor failure — The sensor tells the control board when to run the compressor. If it fails, the system may not cool even though the compressor tries to run.
Quick checks before you call
Check that the Vacation mode (or Energy Saving mode) is not active. If it is, cooling will be disabled intentionally. Refer to your user manual for how to turn it off. Also verify that the appliance is plugged in and the outlet works (test with another device).
Listen carefully: if the compressor (the hum from the back of the unit) is running but there's no cold air, the fault is downstream in the sealed cooling circuit. If the compressor isn't running at all and only the fan is loud, the control board or wiring is likely at fault.
Why this needs an engineer
All three likely causes involve electrical components (PCB, sensor) or sealed refrigeration parts (evaporator). Work on the refrigeration system, compressor, or high-voltage circuits must only be done by a qualified engineer to avoid gas leaks, electrical hazard, or further damage to the appliance.
Attempting to repair these components yourself will void any warranty and may make the fault worse.
When to call SMC Services
Book a repair as soon as possible — the longer a fridge freezer sits without cooling, the greater the risk of food spoilage. If you're in Northern Ireland, SMC Services can usually book a repair within 2-3 working days.
