In such cases, it's best if you contact the repair service. Because here we are not all professionals and therefore we will not be able to give a 100 percent correct answer. And the master in the repair master will be able to take and see what the problem is. Personally, when my air conditioner breaks down, I turned to https://www.airconservicingsingapore.com/. And I am always sure everything will be done correctly and at the highest level. I so throughout my life trust the case to professionals, that is, if I have something broken, I do not fix it myself, but immediately go to repair service.
