Repairing a broken refrigerator

A broken refrigerator usually requires the intervention of a specialist. However, in most cases, a simple check, cleaning and maintenance routine can restart the device.

A refrigerator can be equipped by the manufacturer in different ways to produce cold. The best-known domestic cold system is the compression mechanism. A refrigerator of this type is equipped with an electric motor that compresses the hot freon gas is liquefied by compression, and arriving in the inner wall of the refrigerator, the temperature of the liquid product drops under the influence of decompression. A refrigerator can also work by absorption. In this case, the refrigerator uses a mixture of water, ammonia and hydrogen, while the aggregate is heated by a gas, electrical resistance or oil . The majority of newly manufactured refrigerators use this technique in cold production. This was also the plate of refrigerators, which work with a mechanism called Peltier effect. The plates are covered by the current and produce cold at regular intervals. All these types of refrigerators have their own spare parts and maintenance instructions. So, we must know what type of refrigerator was in the house before considering any manipulation.

Minor faults are easily repaired at home

In the event of a failure of a device such as the refrigerator; the first thing to do is read the receipt of the purchase. This is necessary because the general descriptions of the device here (brand, capacity, power …), and the most important is whether the device is still covered by the warranty or not. When its warranty is still valid at the time of failure, it is advisable not to attempt a repair. You only have to ask customer service support over the phone for advice from after-sales technicians. In the absence of warranty, we can try to find the cause of the failure and repair it if possible or replace the defective parts. In general, there are three most common failures with refrigerators. Regardless of the type of technology used by the refrigerator, faults affecting the regulator or cold thermostat and the defrosting device may occur. On refrigerators, electrical resistance problems can occur due to wear and tear. Finally, on devices using the absorption system, the most common failure is the failure of aggregate or theft. Most of these failures can be solved simply by replacing a used part. But before doing so, read the device's data sheet to find the reference and features of the parts to be replaced.

When to call a professional?

Refrigerators have a longevity greater than ten years, provided that periodic maintenance. Cleaning and defrosting are basic maintenance operations that do not shorten the life of some refrigerator components. However, cases of serious failures, such as gas leaks, engine failures, a problem of gas injector or burner, require the knowledge of a specialist. In addition, some refrigerator models, especially those that work with compression, require special tools to troubleshoot. Only those who have the proper equipment and those who are technically trained can handle this type of refrigerators. Engine replacement and gas replenishment, for example, may only be performed at facilities approved by the manufacturers. It is with refrigerators or diesel, their handling can cause accidents. Repairs to these refrigerators require special skills and can only be performed in specialized repair shops. In a word, in case of major breakdown, it is advisable to ask a quote from a professional to decide on the replacement or repair of the refrigerator.
