Hello JOSETEC2014, the capacitor by its characteristics or at least for its capacity of 12 microfarads, it must be a permanent or running capacitor, this to connect you to a PTC relay, you just have to locate the pins or terminals of the relay itself that match the start and start the compressor and place a cable of the 2 that carries the capacitor, for each of those pins R and S and ready. Now if the compressor manages to start without difficulty, obviously the capacitor's own connection, nothing would have to do with the cooling of that freezer. On the other hand, if the compressor is running, the freezer does not heat the condenser coil and shows no symptoms of starting to cool inside the box that forms the evaporator, in that case you should check the possibility of having or not refrigerant inside the system , by placing a pinch valve in the appendix of the pipe of the service outlet, if already done that, the system has sufficient refrigerant refrigerant inside marked on the low pressure gauge, in that case it would remain to verify the compressor that may have stopped compressing or it could have an obstruction in the capillary or in the filter drier. Check it out. Luck. S @ lu2 friovega63.
Hello, the pressure will depend on the type of refrigerant that the freezer uses to cool, for example if it uses R134A as a refrigerant, the pressures can vary between -2 psi and 7 psi (pounds of pressure) depending also on the outside temperature. You will recognize if the dryer or capillary filter is clogged, if added to the above, that the pressure becomes very negative in the low pressure gauge of blue pressure gauge, below -2 psi, but also goes to perceive that it does not fully heat the condenser, or does it only very intensely at the beginning of it and no heat for the rest, you can also feel and observe on occasions that the filter or the capillary begin to perspire by summarizing water and can even get to form frost on them. To know that the compressor is not compressing enough, it is enough to confirm that the compressor is working at that time, and not to observe in the low pressure gauge, that precisely the pressure in that area does not lower enough to not even approach the values already commented above. If you tap the service outlet and there is hardly any pressure on the pressure gauge, that would mean that the system has no refrigerant, because it obviously has lost it due to a leak or breakdown.
