If you cut the compressor by timer or clock and the defrosting lasts about 20 or 30 minutes, nothing to do with the thermostat, if after that rest time you put the compressor and want to start in several attempts and after those starts well, there are to check the relay, the thermal protector or the capacitor if it brings, but if they are good, it could be the compressor that already has problems or the refrigerant charge that maybe was passed since the compressor is smaller, greetings
Good friend regards. Very interesting your opinion really thank you very much. And if I understand the capacity. And good about the thermostat I have not changed. I have the original 1/6 engine thermostat. The thermostat you have at the moment is that of the 1/5 engine. I'm going to do that test to see how the function does. And really thank you very much friend greetings
