I have a GE 115 Volt Portable Electronic Room Air Conditioner. It seems to be having problems cooling. No water collects in the water bucket although some (still a small amount) will drain manually. Anyone have any suggestions about how to fix this?

No air conditioner will blow 30deg air, The coil will ice up lomg befor that. Most air conditioners that have a setting for this tem, are heat/cool units. Anything below 68 deg on a window air is for the heat. The way an air condition worke is that it pulls room air in and and removes heat from the air. A properly working unit has a twenty deg split, that is if room temo is 70 deg, the temp being blown out will be around 60 - 62deg. The reason an air conditioning unit will not cool a room below 68 degrees is becouse as the evaporater becomes colder the presure drops, and when the presure drops enough the coil will ice up and there will be no air flow. If you are takeing the temp of the air coming out and it is 45 deg's then your room temp is around 65 -68 degs. Thas the best it will do. Now you can oversise the unit to bring temp down faster but this will result in short cycleing.

The person who bought it giving me a hard time here it runs all day and night long gonna cost a fortune in my moms social security number and her name for nothing it is arctic king air i cannot find the corporation at all to call My suggestion was easy to trade this air conditioner at the walmart and check it out plug it in before purchase to make sure it is cold and working must be a factory defect.

We just bought a portable air conditioner at walmart and plugged it in and coldest it will get after 24 hours is 45 degrees it will not get colder. It says that it will get -30 degrees is how cold it will get this is not happening. So we tried to find the company and no record on the web or in yellow pages to call them to find out whats wrong with it at all just wont get colder at all.
