How can I tell if the compressor in a refrigerator is compressing, and when the refrigerator is not freezing, the problem is not always the compressor, it can also be clogging, humidity, oil in the evaporator, etc. I wonder if there is any device to know if the problem is even in compression or elsewhere, without taking the compressor out of the system, testing it out and losing the gas. Many times I need to bring the customer's refrigerator to the workshop to take the test and give the budget. Could you avoid this?
It may even be due to clogging, moisture, oil in the evaporator or lack of gas caused by leaks. The analysis of the causes of the lack of refrigerant must be done carefully so that one has a perfect identification. Therefore, using a logical analysis criterion, the costs and the repair time will be lower. In order to test the lack of compression of a compressor, the manometer must be installed on the low and high pressure sides (suction and discharge) of the system. If there is no compression, the suction pressure will be high to low discharge. The temperature of the discharge line will be lower than that normally encountered and the temperature of the compressor will be high. We recommend that you do not test the compressor outside the system. Taking the product to the workshop, analyzing the problem, passing the budget and performing the reoperation demonstrates concern about the safety and quality of services
