How do i get my newair af 1200e portable air conditioner to stop blowing cold and warm air.

A heat pump is an air conditioner that reverses its refrigerant flow. In the cooling mode, the evaporator is cold to the room and its condenser is hot. In the heating mode, a valve reverses the refrigerant flow and makes the evaporator warm and the condenser cold.

Is it new? There may something wrong with the electronic circuit board not allowing other fan speeds. Try unplugging it for a while and try again. There is a temp sensing bulb somewhere on unit most likely on front where hot/warm air from space enters unit. Make sure you are not recycling cold conditioned air back onto sensing bulb.

Unfortunately there can be several reasons for your AC-14000E portable air conditioner not cooling well. As with most portable air conditioners the filter grates on the rear of the unit can be removed for cleaning. When those are removed you may be able to clean some portion of condenser coils. There is also the possibility that your portable AC has a refrigerant leak in the system and will not be able to cool effectively without a repair (which usually costs as much as a new portable AC). Portable AC's are not designed to be recharged and operate on a sealed refrigerant line so even finding someone able to repair it may be a challenge. Your best bet is contacting the company you bought it from and talking through some solutions, they most likely have experience with these units and should be able to help you.

I just experienced this problem myself. What helped me was cleaning out the lint trap. My guess is that the until sucks in air through there, then conditions it. Blows the cold air out the top, and hot air out the tube. When it can't suck a decent amount of air in, the condenser can only condense so much of that limited amount of air. When it runs out, the unit just runs the fan until enough air has been condensed.

My lint trap was filthy, hadnt Bern cleaned in years. Soon as I popped it off, the unit started belching out cold air nonstop. Clean your lint traps! Don't make my mistake!

if it is also blowing cold air out of the other vents you need to vent the hot air its blowing outside

my unit turns on and u hear the compress try to turn on and it goes off ....but the fan still blows ...

I have a Amcor AF 1200E air conditioner, it only blows warm air and it is real dirty on inside filters, we took out 3 filters but there is still dirt on filters behind these, do we take it apart to clean, I would like a manual , do youknow where I can download one at? thanks

sounds like the unit has a low charge and is cutting out on a low press safety. This is more then likey not something you can fit yourself most of this units are not really serviceable with out cutting the lines open and adding a valve. If the unit is still somewhat new you can try for a warranty repair, if not you are better off to replace it.

seems like the coolant has leaked out

Either the unit is really dirty or it is low on refrigerant. A unit tha is low on refrigerant will start off cold and withing a few minutes, start warming up. If you aren't seeing any water its because of one or both causes listed.
