Why is the unit blowing out warm air and the motor goes from high to low, the display window shows E5

need model number as there are several different model numbers.

Unplug for 10 minutes e 5 usually indicates low voltage protection

Change capacitor motor and outdur working almost
But 3 minute working ok
After E5 error show display screen on indur with outdour fan stop but compressor sound

Sounds like high blower relay is bad

high speed relay or bad fan motor.

have you removeing the filter from the front of it sometimes colecting all that dust in it can cause it send only luke warm air out also if youve had it on none stop it can sometimes freeze but then letting it sit for a couple hours to a day usually solves that

Hi, no, im sorry if it is on low already, it can't be changed to go any lower. The only thing I can come up with is the fan motored is wired wrong, and they have the high or med lead connected to the low speed, as it should run slow. On a central air system, there is a board that is in the indoor unit that shows the fan speeds, and they can be changed.I didnt look up your unit, and if it is a central air and not a window unit, you can change the speeds at the board. The wires are colored, blue is normally low, red is Hi, and blk or yellow is med. If this is a window unit, there is nothing much you can do. If you know anything about electrical, and you have a 3 speed fan, pull the cover to get to the switch back, and see what leads the have terminated to the switch. They may have it miswired. I wish you the best of luck,

"Hi" means your compressor has gone off on a high temperature limit. Basically, your outdoor coil is dirty and needs to be cleaned or your outdoor fan has stopped working. An air conditioner works off a simple principle of removing heat using a low temperature and low pressure refrigerant. Your compressor does what it is called. It changes that low temperature, low pressure refrigerant into a high temperature and high pressure refrigerant. Your outdoor fan blows over that high pressure gas and it blows out hot air. First thing to check is to turn your unit on, and go outside and feel if you have any air blowing out the back. If you don't, you have a bad fan. If you do, you need to clean your coil. Spray some simple green on your outdoor coil and let it sit for about 15 minutes. Then grab a hose and under low water pressure, wash out your coil from top to bottom pointing the hose in a downward direction. You do not want to point the hose straight into the unit. Make sure you disconnect the power and allow it a couple hours to dry before you plug it back in. If it's just a dirty coil, you should be good to go after that!!

i am air con tech and i face all ready this problem may be it will help u . e5 error is ur air con not have gas becoze of that the low presser switch give error on disply thanks best regard for all. pls let now if its help full
