Question about Heating & Cooling
I have bought a LG S186GH Air Conditioner last year. It worked the winter and the summer. Now its winter again and It doesn't heathen anymore. I turn it on, and it only has cold wind, no warmness.
What should I do?
Hi, I looked up you're unit to see just what I already assumed it was, a split system, ductless,9kb.t.u. Ok, 1st go to the outdoor unit to see if it comes on when you turn your t-stat to heating, and be sure you lower the temp. enough to do this test. There maybe a time delay before it starts up, but not long,1-1/2 min. If it doesn't start up, we know that there is a problem.If not on, make sure you check for the power source, locate the breaker it may have tripped, or right at the unit there is a elect. box that should contain 2-fuses.They may be hidden from site under a shield you may have to remove. Check all of this only if this unit is not running. Reset breaker, or replace fuses if not running.If that was the problem and it was off, and now its on, you will have to watch it and if it continues to loose power, you have a problem in a componant as the compressor, condenser fan motor, open or shorted run cap, contactor Ect.You could have developed a freon leak, and it could be off on low pressure.If it is running, it still could be low on freon, reversing valve not changing over, many things can cause this Im afraid to say.The main thing to do or to start, would be to make sure that the outdoor unit is on, fan on, and compressor running if you listen at where the wiring and copper lines enter.You may need to call a tech if you check these things i have suggested and you have no luck. Please be safe and let me know, and we can go from there before you call anyone out.
