AEG Refrigerator Giving Alarm and Not Cooling

Hello, my AEG refrigerator has been giving an alarm for two days and is no longer cooling. Today, I noticed that the motor was overheating, so I unplugged it. One person suggested that the refrigerator might be out of gas, while another said the motor could be burnt out. We’re unsure of the exact problem, and I would appreciate any help you can provide to figure out what’s going on. I need this issue resolved as soon as possible since it’s affecting my daily life. Could you assist me in diagnosing and fixing this problem?
