Air condx woes
about this time last year, it started to get HOT out here in East County, and i just couldn't take it anymore. I HAD to have AC, no matter what it cost, no matter what.
So I went to the Home Depot and bought a LG 9K BTU portable unit to cool my bedroom.
It has started to get flaky.
Right now it is cooling great. But this afternoon, when it was in the 90s, it would run for abit, put out cool air, and then I would hear something switch and it would just put out hot air. It seems the hotter it gets, the less it cools. On nights when it is in the 70s or 80s, it puts out ARTIC air. But let a HOT DAY sneak in and it is more or less a FAN! And a fan blowing HOT AIR!
I try and restart it, which works for a short while till it switches to the hot air mode.
Now that the night has cooled down abit, it is blowing cold air constantly again.
I tried taking it apart but didn't get anywhere. I don't know anything about AC. this cost me around $400 last year, and I am ready to go to Home Depot and buy another, as the HOT WX is promised this week.
What is wrong with this thing? Maybe it is a 400 dollar door stop now.
Try cleaning the coils and condenser fins.
Even though it may now be out of warranty, sometimes the manufacturer's 800 number customer service and technical support will give you some simple quick free advice over the phone of how to fix it. Also ask many "different" store employee people at the Home Depo where you bought it, for some free advice of how to fix it.
Is the condensate resevoir full? Mine claimed never need emptying, on hot days it is full in an hour.
Wow, I have had nearly the same problem, with nearly the same model, just in the past week or two!
I have never owned a portable AC unit before this, so perhaps they are all this wacky. I bought the unit in Craigslist in near-new condition (could not even tell that it had been used). It works perfectly for the first couple weeks I had it.
Mine displays error code "E4" after a while, which should mean that the coils are icing up, according to the manual. However they never appear that way. I cleaned them just to be sure.
I read and re-read the manual (which is not entirely clear nor helpful), and searched online for information.
Air filter is clean, reservoir is empty, and the darn thing will still do this!!!

Sounds like low Freon. Either a low pressure switch is shutting down the compressor or is causing the compressor to overheat and an internal sensor is cutting it off.
Any reputable AC shop can check it out, and recharging should be a lot less than a new unit.

Truth of any AC unit.. it takes the heat out of the air withthe evaporator and releases into other air with the condenser. The condenser needs to be in somewhat cooler air than the heat of the condenser.
Yu cant transfer equal heat to equal heat. a window Ac should be kept in the shade, so the condenser is cooler than outside air..
If it blows super cool at night, its not a freon problem, the freon either works or it don't.
Most likely its a heat exchange problem. If it can't get rid of the heat, the freon won't re condense to a liquid and likely has a shut down function.
It might also be a high pressure cut out switch. make sure the condenser is clean and the Evaporator isn't icing. Try blowing a fan across the condenser while it's running. If not have it checked for a leak
