Is your refrigerator working but not freezing? This is a fairly common problem. The issue can affect both chambers at once, or it can occur only in one of them. For example, in the refrigerator compartment the temperature is normal, but in the freezer there is a thaw. Or vice versa. There are many reasons for such a malfunction. They are all very different, so fixing the problem may require different efforts and costs. The compressor works without switching off at all, and in the refrigerator it is getting warmer and warmer. Probably, there was damage to the cooling circuit, and the freon evaporated from it. It is easy to check on your own: gently touch the condenser with your hand (the grill behind the refrigerator). Normally, it should be hot. If the condenser is cold when the compressor is running, it means that there is a refrigerant leak. You will need to find the place of damage, re-seal the system and fill in new freon. To do this, you need to have special equipment. The refrigerant should be filled with the same brand as the refrigerator was originally charged. Typically, blockages appear in the capillary tube and filter drier. A common cause of capillary clogging is the use of low-quality freon with a high moisture content and refueling without preliminary vacuumization. Water freezes in the lumen of the tube when the refrigerant evaporates and clogs it. In addition to moisture, solid particles, such as compressor wear debris, can clog the capillary and filter drier. A characteristic symptom of any blockage in the system is a heavy, strained hum of the motor. To get rid of the problem, the system is cleaned with special hydraulic equipment, the capillary tube is purged, and the filter is replaced. If it does not turn on at all, then it is clear that there will be no cold. But it happens that the compressor is still running, turning on and off at the prescribed time. At the same time, it can hum more than usual, click, rumble, gnash. This means that the motor has already worn out, has lost some of its power and cannot pump freon under sufficient pressure. To accurately determine the breakdown, you need to check the compressor. In case of a compressor malfunction, it is usually replaced with a new one, much less often it is repaired. In models with the No Frost system, heaters sometimes burn out, which defrost ice on the radiator and fan. Then the blades are covered with a thick layer of ice and stop rotating. Cold air does not circulate and remains at the radiator, and gradually warms up in the chamber. In this case, the compressor also suffers. After all, the thermostat makes it work more and more intensively in order to reduce the constantly increasing temperature. The icing on the fan can be seen with the naked eye. But defrosting is not going to help. If the heating element is broken, it must be replaced, otherwise the problem will very soon repeat itself.

How to Drain a clogged line in Goodman AC Unit?
Before you start calling a contractor to come and see your unit, we should tell you it’s normal for your air conditioner to create some condensation. In fact, your condenser likely has a drain pan underneath to collect droplets.
