I talked to a technician too and he tells me that maybe the thermostat was not the problem of entry, that it surely has a big loss and was cooling too much for that (I think that explanation is very rare) and that once it was unplugged for a long time it didn't cool again ...
If it was unplugged for a very LONG time, I don't know a year, months, etc., because then if the technician is right, because the refrigerant leaked little by little for some internal leakage of the pipe or pipe, you will need to check it. press, until now I saw your comment, greetings
Thank you very much for your response, the outdoor grill does not raise the proper temperature (I already felt it). It is not strange that one day it went cold and began to freeze everything and after the change of thermostat no longer cool and never cut for not reaching the right temperature?
It can be strange but not impossible, sometimes someone wakes up laughing and an hour later dies of a heart attack
Undoubtedly if it does not heat the condenser is not compressing gas, the other thing that can happen is that the compressor stopped working due to breakage in its mechanical part, only by measuring pressure can a correct diagnosis be given.
