What we repair (and what we consciously do not) 🤝
At We.repair, we value clear agreements and honest advice. Fortunately, we can resolve the vast majority of fridge problems quickly, affordably, and right at your home.
These faults we resolve daily ✅
In most cases, it involves a faulty part that we can easily replace. We.repair carries out the following repairs on freezers:
Temperature sensors and thermostats: If your freezer is defrosting or the alarm keeps going off, we replace the sensors or the thermostat so that the freezing temperature is correctly regulated again.
Electronics and No-Frost systems: We replace faulty circuit boards (control modules), broken internal fans, and we repair the automatic defrost system (defrost heaters and sensors) so that your appliance remains frost-free.
Mechanical parts: A good seal is crucial. We replace worn door seals, broken hinges (especially a common problem with built-in freezers), and broken door handles.
For all these issues, our We.repair technicians have the right expertise and spare parts on hand!
What we do not repair: Refrigeration defects ❌
However, there is one specific category of repairs that we do not carry out for household freezers and refrigerators: to perform: the so-calledrefrigeration repairs. This includes soldering gas leaks, refilling refrigerant, and replacing the compressor (the motor).
Almost all specialised repair services refuse these interventions. Here are three clear reasons for this:
Inaccessible leaks: A leak in the cooling circuit is often hidden in the insulation walls (polyurethane foam) of the freezer.
Too expensive: Locating, soldering, vacuuming, and refilling is very labour-intensive. The labour hours accumulate to such an extent that the cost almost always exceeds the residual value of the freezer.
No certainty: Even after an expensive gas or compressor repair, the chance of a new leak is high. We want to avoid you paying a lot of money for a temporary solution.
What if our technician identifies this problem on-site?
Because a faulty control module and a gas leak can sometimes present the same symptoms, a diagnosis is necessary. If it turns out after measuring by our technician that your freezer is irreparable due to a leak or broken motor? Then we will be transparent. We will stop the repair immediately to avoid further unnecessary costs for you. In that case, we will charge only the fixed analysis cost. This way, you have certainty and honest advice to purchase a new freezer.
Common problems with freezers 🧊
These are the defects that our technicians encounter weekly:
The freezer no longer freezes (or insufficiently)
You often notice this when ice creams become soft or bread thaws. If it’s not due to the power supply, then the thermostat or temperature sensor may be faulty. In No-Frost models, a jammed fan can cause the cold air to stop circulating.
Extreme ice formation (thick layers of ice)
Is there a thick layer of ice on the walls or between the drawers? Often, a worn or damaged door seal is the culprit, allowing warm, moist air to leak in. If your freezer is 'No-Frost' and it still freezes completely up, then the automatic defrost element is most likely broken.
The alarm goes off or the red light is on
Almost every modern freezer has a red ALARM light or emits a beeping sound. This is simply a warning that the internal temperature is too high (usually warmer than -10°C). Does this happen after loading a lot of new, unfrozen groceries or after the door has been open? Then there is nothing to worry about. If the alarm persists for hours, then the freezer is faulty.
The freezer makes a loud or strange noise
A ticking, buzzing, or soft bubbling sound is normal. But if you hear a loud rattling or clattering? In No-Frost models, it often happens that ice buildup scrapes against the blades of the internal fan. A persistent loud hum may indicate a worn compressor.
Error codes by Brand: What do they mean? 📟
Red light, flashing triangle or AL / Alarm: This is the universal notification for brands like AEG, Beko, and Whirlpool that the temperature in the freezer has risen too high.
Bosch / Siemens / Neff (e.g. E or AL): A flashing temperature display combined with an alarm tone often indicates a faulty temperature sensor (NTC) or a problem with the control module.
Samsung / LG (e.g. flashing display blocks): For these brands, error codes often indicate a fault in the No-Frost system (defrost sensor or heating element) or the fan motor.
Miele / Liebherr (e.g. nA, F3, F4): 'nA' (no Alarm / not cold enough) is a warning for temperature loss (e.g. after a power failure). F-codes usually indicate a faulty sensor.
You can try this yourself before calling us 🛠️
The 24-hour defrost cycle: Is your freezer not working properly or making noise? Empty it, unplug it, and let it fully defrost with the doors open for 24 hours (do prepare towels!). This often resolves blockages in the fan or temperature sensors.
Check the seals: Wedge a piece of paper between the door and the cabinet. Can you easily pull the paper out while the door is closed? If so, the seal is worn and the freezer is leaking cold air.
The Super-Frost button: Use the 'Super' or 'Quick Freeze' function if you have loaded a lot of new items. This temporarily disables the thermostat and allows the motor to run continuously to quickly return to temperature. Don't forget to turn it off afterwards (unless this happens automatically).

How does a freezer actually work? The secret of freezing cold! 🥶
Although we often see a freezer as a device that simply "makes cold", its operation is purely based on moving heat. A freezer works exactly the same as a refrigerator, but is set to achieve temperatures well below freezing.
Stealing heat
The system in your freezer extracts the remaining heat from the food and from the air in the freezer, and pumps this heat outside. This explains why the grille at the back or the side walls of your freezer feel warm, even when the inside is -18°C!
This happens through a closed circuit with a refrigerant. The compressor (the motor) compresses this gas, making it hot. Through the condenser (the warm grille on the outside), the gas releases its heat to your garage or kitchen, and becomes liquid again. This liquid is forced through a tiny valve and evaporates in the evaporator (the pipes in the walls of your freezer compartment). In this process, heat is absorbed from your food, after which the gas flows back to the compressor. The cycle is complete!
3 Fun Freezer Facts💡
A No-Frost freezer has a built-in heater! Sounds illogical, right? To prevent ice from forming, a No-Frost freezer secretly switches on a small heating element several times a day to melt invisible ice on the evaporator. That's why you never have to defrost them.
Packed full is better than half empty. Just like with a fridge, the frozen mass (your bags of chips and frozen vegetables) helps to keep the temperature stable. When you open the door, less cold air escapes if the drawers are filled with solid, frozen blocks.
The magic -18°C. Why is your freezer set to -18°C by default? At this temperature, the activity of enzymes and bacteria is almost completely halted, allowing food to remain safely edible for months or even years without loss of vitamins.
Frequently asked questions about freezers (FAQ) ❓
Can I place my freezer in an unheated garage or shed?
This depends on the 'climate class' of your appliance. Many standard freezers are designed for spaces between +10°C and +43°C (Climate Class SN-T). Does the temperature in your garage drop just above freezing in winter? Then the oil in the compressor can become too viscous and the appliance may break down. Check if your brand has 'FrostProtect' or similar technology; these can often be placed in ambient temperatures down to -15°C.
How long will my food stay good during a power outage?
As long as you keep the door or lid closed, the insulation of a modern freezer is excellent. In a full freezer, food will stay safely frozen for an average of 12 to 24 hours. In a large, well-stocked chest freezer, this can even extend to 48 hours. So absolutely do not open the door to "just check" if the power goes out!
What is the difference between Low-Frost and No-Frost?
In No-Frost, a fan circulates cold air and moisture is continuously removed; therefore, ice never forms and you never have to defrost. In Low-Frost or Smart-Frost, the freezer pipes are tightly wrapped around the inner container instead of being exposed. This results in about 80% less ice formation than in a traditional freezer, but you still need to defrost it approximately every two to three years.
