It never worked well, it had to be loaded almost every year, many have come to load it (or get me money), let it work and stop walking after 20 days. Last year I walked when I wanted to, but when I walked, I was perfect, with that symptom, I wanted to change sensors, the entire control center for a generic one and they even offered to leave it directly with a switch for me to turn on and off the compressor ... That's when I got tired and started to get my hands on, I changed the cylindrical capacitor, it was great for a while, then I didn't turn on the external fan, again, they wanted to see me and I solved it by changing the $ 37 square capacitor and it was perfect all last year . We arrived last December, nothing was going on, I bought the hoses, pressure gauge, I followed the steps I read here, and holy remedy, perfect functioning, pressures ok, all good. It lasted until two weeks ago, which began to cool sometimes yes, sometimes no; and combined with that the external fan bearings broke down making noise. Last Saturday I changed the bearings, it was perfect, but the compressor did not start, I changed the capacitors, this time with no positive result. And here is the problem: I misconnected the cylindrical capacitor, the compressor ... it will have been 5 minutes. I connected the S terminal that goes alone, to the same terminal where a lot of wires go, and also one of those that goes to the terminal that goes a lot, alone to the other (I upload the diagram). At that moment with the wrongly connected capacitor I put gas in it and the pressure in the pressure gauge did not change, it did not exceed 0. I noticed the capacitor, I corrected it, the compressor at that time did not turn on more ... I left it. I tried later, it started (it looks like it had cut thermal), I put gas (already having no idea what state of charge it is), it stayed at zero, and at the time of putting it it did not rise to more than 10, and it was frozen , all white, the high peak (the fine one) and at that moment I left it. Today Monday I started again. The compressor turns on, the external fan too, but does not cool. With the compressor off I touched the lobe and no gas came out, I thought it was super empty and that the loss that the whole life had had the equipment would have enlarged; But with the compressor running there is pressure on the loading valve, the high pipe starts to cool, but the air does not come out cold ... And here is where I am lost and I do not know how to continue, someone who is well on the subject where would it start? (I don't have a R22 bottle). 1- I buy another bottle and try to refill? 2- Empty all the gas inside and charge with new bottles? 3- Due to the fact that the compressor starts, can I rule it out as a problem? I do not have an amperometric clamp, but if it is essential I would buy it. 4- Since both compressor and fan start, can I discard the capacitors? 5- I would like to disassemble the outdoor unit to access the compressor and be able to make a visual inspection to see if there is any gross loss, or to measure the windings, but the equipment is against two walls, so it is quite difficult for me and not I know if it can be essential. 6- Call someone to take care of zero and charge me whatever I want ... :-( Sorry for the corn, I have no ability to synthesize. Thank you!

Hello, the first thing you have to do is, look for the loss of refrigerant. In these cases I would recommend that you uninstall the equipment, take out the pipes and make a pressurization to the units individually to search for the leak, for this you can get a bottle of those that come for the Drago type siphons, with an adaptation you can use it to pressurize at 250psi and see where you lose. Once that is solved, make it empty (I see that you do not have a bomb, try to get someone to lend you, they are not cheap to make the expense just to see the airs of your house) when you have the vacuum ready you take out the pump along with the hose (only the hose that is plugged into the pump), you plug the hose into the bottle, you open the gas a little and you screw it to the manifold so that the air from the hose comes out and there it charges ( without turning on the split ) to "break the vacuum", when I enter a little refrigerant there you turn it on and continue charging until 65psi. Regards.-

Hi Sergio, I would like to clarify this comment of yours But the team is against two walls, so it is very difficult for me and I do not know if it can be essential I am struck by the two walls on which the outdoor unit is located and that you also say, having spent 10 years with your Split and that this has never worked well for you, by chance one of the walls is close to the air outlet of the fan, of the outdoor unit, as if blocking that outlet. I also assure you that it is absolutely essential that you disassemble and check how to look for a possible outlet, mainly by the condenser, especially if it is a condenser of those that have in addition to the finned, the aluminum pipes too. The capacitors entirely made of aluminum are more prone to sulphation and, therefore, to the outlets than those made of copper and aluminum. Pressurize the disassembled unit with nitrogen (condenser and compressor only) soak it in a tub with clean water that allows you to see through it and look for possible bubbles that would come out, if there is any outlet in that part.
