How do I know if the compressor in a refrigerator is compressing?

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 out of the system. Taking the product to the workshop, analyzing the problem, passing the budget and performing the reoperation demonstrates concern for the safety and quality of services.
