Fridge tips: expert repair & maintenance advice | AEG

A fridge quietly protects food day and night, which is why warmer temperatures, water build-up or unfamiliar sounds deserve prompt attention.

Important: If your fridge is no longer cooling safely, food storage may be affected. Only perform user care described in the product user manual and contact service if cooling does not improve.

Common fridge problems Q&A

The most common fridge issues I encounter are poor cooling performance, water collecting inside or underneath the appliance, unusual noises, frost appearing where it shouldn't, and food freezing in the fridge compartment. Some of these problems can be caused by blocked airflow, maintenance issues or how the fridge is loaded. Others may point to a technical fault that requires professional diagnosis.
If a fridge isn't cooling properly, it's important to address the issue quickly because it can affect food safety. Common causes include blocked ventilation, poor door sealing, frost build-up or a problem with the cooling system itself. I also see cases where the installation doesn't allow enough airflow around the appliance. If food is no longer staying properly chilled and basic maintenance doesn't solve the issue, I would recommend arranging service.
Water build-up can happen for several reasons. One of the most common causes is a blocked drain hole, which prevents condensation from draining away as intended. During warmer months, high humidity can also lead to extra moisture inside or around the appliance, especially if the door is opened frequently. If water continues to collect or appears alongside cooling problems, it's worth having the fridge inspected.
Some sounds are completely normal in a fridge, particularly when the compressor starts and stops as the cooling system adjusts temperatures. However, if you notice a new noise that's louder, more frequent or significantly different from normal, it may indicate a problem. In some cases, compressor vibrations can also be transferred to nearby cabinets or furniture, making the noise seem worse than it actually is. If the noise continues or is accompanied by cooling issues, professional service may be needed.
"Frost or condensation inside a fridge is often linked to warm air entering the appliance. This can happen if the door isn't sealing correctly, the door is opened frequently, or large amounts of warm food are placed inside. High humidity can also contribute to frost formation. If frost repeatedly builds up despite normal use, it may suggest that the fridge is no longer operating as efficiently as it should
Food freezing in the fridge compartment is a surprisingly common issue. It can happen if the temperature setting is too low, if food is placed too close to cooling vents, or if airflow inside the appliance is restricted. Sometimes it can also indicate a temperature control problem. If food continues to freeze despite adjusting settings and following the recommendations in the user manual, the appliance may need professional attention.
A fridge may seem to run continuously if it's working harder than normal to maintain temperature. This can happen when warm air frequently enters the appliance, the door seal isn't working effectively, airflow is restricted, or frost build-up is affecting performance. During hot weather, longer running times can also be normal. However, if the appliance suddenly starts running constantly and cooling performance is declining, it's worth having it inspected.

Maintain, repair or replace

Should I repair or replace my fridge?

The answer depends on the condition of the appliance and the nature of the problem. If the fridge has been reliable and the issue is relatively isolated, a repair is often the most practical solution. However, if faults keep returning, cooling performance has declined significantly or a major component has failed, replacement may be the better long-term option. A technician can help determine which choice offers the best value.

What maintenance should I do regularly?

Consistent care can go a long way towards maintaining cooling performance. I recommend keeping air vents clear, cleaning the interior regularly, checking that the door seals are clean and in good condition, and ensuring the drain hole remains free. It's also important not to overfill areas that rely on airflow. These simple habits can help your fridge run more efficiently and prevent common problems.

DYI or professional repair

Is it safe to repair a fridge yourself?

Routine care and maintenance described in the user manual are generally safe for most users. However, repairs involving the cooling system, electrical components or internal parts should always be left to a qualified technician. If you notice poor cooling, unusual smells, persistent water build-up or electrical issues, it is best to seek professional support rather than attempting repairs yourself.

When should I book a repair for my fridge?

I recommend arranging service if the fridge remains warm, cooling becomes inconsistent, food is no longer staying properly chilled, or water continues to collect despite regular maintenance. Persistent frost build-up, unusual noises and electrical issues are also signs that the appliance should be inspected. Acting early can often help prevent more significant problems later on.

Book a service

Final advice from the expert

A fridge works around the clock, so even small changes in performance shouldn't be ignored. If you notice warmer temperatures, frost, unusual sounds or water where it shouldn't be, it's a good idea to investigate early. Regular maintenance and timely repairs can help maintain reliable cooling performance and protect the food stored inside.
