Why isn't my new fridge cooling?

Fridge no longer cools, what should I do? | 7 possible causes

You have done your shopping and while you were pouring the shock: your refrigerator is no longer cooling. Instead of the usual cool breeze, warm air welcomes you from the kitchen appliance. If the refrigerator does not perform its function, perishable food cannot be stored, which will be a problem especially for families with bulk purchases. The causes of this problem can be varied.

The refrigerator no longer cools and your food is in danger of spoiling? Refrigerators have become one of the most important kitchen appliances without which modern nutrition would not be possible. For this reason, it is important that the device works properly so that perishable items such as dairy products, meat, vegetables and fruit are not used up immediately and are available for a longer period of time. Since refrigerators consist of several components, damage can occur even with new devices, which must be fixed in order for the device to work again. In the worst case, a new device is needed, but that is rarely the necessary solution.

Possible causes

Refrigerators have various components that either wear out or damage. For this reason, before applying a solution, you need to find the possible cause that is responsible for the lack of cooling performance. However, before you investigate the cause, you should consider the Empty the refrigerator and store the perishable food in cool boxes, cool bags or other refrigeratorsif you have more than one device available. There are seven typical causes of a malfunctioning cooling system, each of which needs to be addressed differently.

Interrupted power supply

The refrigerator no longer cools, but you haven't been out of the house for long or have you taken a bath? If the refrigerator stops cooling from one moment to the next, an interrupted power supply may be the reason. If this is restored, the device will work properly, but you will first need to find out what is breaking the power. The following causes could be the reason:

1. Is the cable plugged in correctly? If the socket is freely accessible, the plug can be accidentally pulled out of the socket. Plug it back in and as soon as the plug or cable is not damaged, you can turn the refrigerator back on.

2. A broken cable or a damaged plug however, is a bigger problem. Look for spots that indicate damage, such as broken wires. Then contact an electrician to replace the cable. If you have the necessary knowledge, you can change the cable yourself, but you must work with care here.

3. Check the fuse box, especially after a power failure. The fuse should be activated so that the power supply is possible at all. If the switch for the kitchen or the room in which you are storing your refrigerator is wrong, press it so that the fuse is "inside" again.

4. Maybe it is the socket? Try a different outlet or check an extension cord or power strip to see if it works or is damaged. Usually there is a problem here that can be easily resolved.

Tip: the cable is often not damaged, just kinked or heavily knotted. In this case, untangle it and make sure that it does not kink, for example by hanging it up.

Incorrect thermostat setting

Perhaps you have set the thermostat incorrectly? Sometimes it can even happen that it adjusts itself due to an object, which could also lead to a warm refrigerator. Check the thermostat, i.e. the wheel with the numbers inside the refrigerator, to see whether it is set to 1 or 0. These are the warmest levels in the refrigerator. Then just set the thermostat level 2 or 3, to solve the problem.

Tip: many modern refrigerators do without a wheel as a thermostat completely. With these, all of this is done via digital settings that cannot be set differently by mistake.

Damaged thermostat

If the thermostat is not set incorrectly, it may be damaged. If this is the case, the refrigerator will feel a little warmer and will not cool even if you reset it. The problem: in order to determine a defect, you have to have one Hire a specialistbecause the refrigerator has to be bridged. At the end of the day, he has to completely replace the thermostat so that the refrigerator can be used again. The costs vary significantly in price and are influenced by the brand of the refrigerator and the thermostat. In the case of particularly old refrigerators, it may even be advisable to completely replace the device.

Defective door seals

Fridges only cool when they are closed. Because of this, you have to take care that the doors don't open on their own, which is not a problem for most. However, very few people notice a defective door seal that has either worn through over the years of use Wear and tear, violence or incorrect use can arise. You can tell whether the door seal is defective when cold air escapes from the closed door. In this case, the cold inside air is replaced with the warmer outside air, which greatly reduces the cooling performance. Then check the door seals for:

  • Cracks
  • Bumps
  • Foreign bodies stuck in the rubber

Alternatively, put a sheet of paper between the door and the frame and close it. Then try carefully pulling the paper out of the refrigerator. If it is tense, the seals are OK. If it can easily be pulled out of the door at one point, the seal will no longer work there. You should have these replaced, which will cost around 100 euros from a specialist, depending on whether special seals have to be ordered.

Dusty condenser tubes

A refrigerator does not cool if the condenser tubes are too dusty or dirty. Don't know what the condenser tubes are? These regulate the heat dissipation caused by the cooling inside the device and can be seen as soon as you look at the back of the refrigerator. There you will find pipes that are arranged in a serpentine shape and emit heat. If these are dirty, the heat can no longer be given off and remains in the device. Once you clean them, they'll work properly again. Proceed as follows:

  • turn off the refrigerator
  • store the food in cooling containers
  • wait for the pipes to cool down
  • clean the pipes with a duster
  • stubborn dirt is removed with a brush
  • then switch on and refill the food

Damaged cooling system

If the cooling system is damaged, it is often necessary to replace the entire refrigerator or to accept an expensive repair, since coolant cannot simply be topped up. Causes of a damaged cooling system are, for example Scraping ice or rustingwhich over time can lead to one or more fine hairline cracks or small holes through which coolant escapes in the form of gas. If the cooling capacity drops, pay attention to the following signs inside the refrigerator:

  • soft hissing
  • Bubbling noises
  • Cooling extremely uneven
  • Formation of unpleasant odors

If none of the causes mentioned above is the reason for the poor cooling performance, you must have the device checked by a specialist.

Compressor problems

A damaged compressor can be just as expensive as the cooling system. The compressor compresses the refrigerant so that it can function at all. If the compressor is damaged or does not work properly due to a defect in the control, the cooling capacity is significantly reduced. You can tell whether the compressor is the cause if you set the thermostat to another level and then you can hear a whirring noise. This whirring noise should be audible every now and then when the compressor is doing its job. If this whirring does not occur, you must hire a specialist and have them checked whether the compressor needs to be replaced or just readjusted.
