AC Wall unit is blowing hot air

The wall outlets where the A/C unit was plugged in all shorted when I was using an electric drill. I flipped the circuit switch and the AC came on, but now it is only blowing hot air. I do not think the problem is freon especially since is started to blow hot air after it was shorted.
Please help.

Bit difficult? Brand/type of this AC?
Can't see what controls what from here.
Your fan works, but I can't see your compressor working to compress the freon (or what ever is in there).
So give some more details about electrical connection.
2 / 3 phase /grounded?
Suppose the unit is disconnected now and thawed up?

Wall AC Unit blows cold air for a little bit then blows hot air. If I turn it off for a while, it will do the same thing.


When you mansion water in the pan, do you mean the indoor coil pan or the outdoor catch "pan"? I've seen some models have a drain plug that's on the bottom of the outdoor panel or underneath. And that plug should remain installed. It uses that water to cool the copper freon tube that curves along the bottom of the outdoor section. With plug removed it can overheat. Basically it does not drain onto the ground outside, it retains its water. And the air entering side of outdoor coil is clean? May sound like repetition(forgive me). The side you see clearly is the air leaving side. The dual shaft motor has a run capacitor that may be weakening. And the outdoor air that passes thru the outdoor coil may be recirculating out then directly back in to the unit causing it to overheat. Anything blocking airflow outside? 10 mins of runtime then shouting down tells me its overheating. It may even be the electrical circuit. Loose connections can cause high amperage, low voltage issue and cause the ac load to over amp. Over amp=over heat. Hope this helps!

AC UNIT TRIPS THE BREAKER WHEN PLUGGED DIRECTLY TO WALL OUTLET AND FLIPS THE SURGE PROTECTOR TO OFF ALSO. WALL OUTLET WAS REPLACED AND STILL THE SAME ISSUE.


The problem might be in the compressor or fan motor. The compressor pulls a lot of amps, and much more if it's jammed or binding. The fan motor will do the same.

Wall ac in off position plug in surge protector blows instantly


It may be possible the it has fried the surge protected internally causing it to short out or blow when plugging in. I would try using another surge protected if you have one or if possible replace the cord going to the unit with a new one and see what happens. Also possible that the outlet your using went bad during the storm as well. Don't know 100% but should be a couple tips to help get you going.

My airconditioner has been on energy saver for almost 2 days and will not come on what should be do


If this is a window or wall unit. Turn the Master ON/OFF Switch to OFF. Unplug the unit and wait 12-15 minutes. Then, plug the unit back in and turn the Master ON/OFF Switch to ON. Set the controls on anything except energy saver. If the unit then operates as it should, let it run for at least an hour before switching it to Energy Saver Mode. If that's the way you want to operate it. If it doesn't restart and run like it should or it shuts OFF on Energy Saver Mode, there is a problem with one of the setting sensors and needs to be replaced.

Also, while you have the unit unplugged, check the outlet to make sure it's still active. You can do this by plugging in a lamp. If the lamp doesn't work, the circuit breaker for that outlet has been tripped in your home's circuit breaker panel and needs to be reset. When you plug the AC unit back in and it trips the breaker again, there is an electrical short or overload in the AC Unit.

Please keep in mind everything I suggested is based on your AC being a 120 volt window or wall unit.

Hope this helps you solve the problem.

For a/c unit, is there an adapter available or do I need a new plug cord


Actually you should buy and install an AC wall outlet. An AC uses more amperage than most any other appliance due to the fact it has 2 motors the compressor and the blower / fan motor. An AC wall plug has larger terminals so that the plug does not ever heat. Changing the cord to a different and smaller terminal plug is a bad choice due to the danger of overheating the wall outlet terminals. You can buy the AC horizontal terminal outlets at any hardware store. Unless you have a 110V AC unit you will also have to run a 220V #10 Romex (3 wire) with ground to the outlet to be in code.. An AC unit 1 HP (10,000) BTU or larger requires over 15 Amps for start up. Those that are 20,000 BTU or larger obviously require more than 15 amps as a power source.

Thanks for using FixYa.

My Fedders A7DH45B2A dehumidifier (about 4 yrs old) continues to trip the fuse embedded in the outlet on the wall in which it's plugged in.. What gives??


either try a different outlet to see if the G.F.C.I. is bad on this outlet or if the dehumidifier trips on another line it could be the units motor start capacitor that shorted or the compressor is bad

Window or wall mount


The differance between a window and wall mounted A/C is the mounting system.
Window units are usually smaller BTU systems they set in the window, so you do not have to cut a hole in the wall to install it.
For a bedroom say 10 x 10 you can use @ 5000 btu it plugs into a standard 120 volt electric outlet. If the room is bigger then go bigger say @ 6000 btu or so. Take your room dementions with you when shopping for a unit. sometimes they have sizing on the side of the unit box.
Wall units are usually larger units. Like whole house 18,000 btu
they slide in and out of the case and use a 240 volt seperate circuit.
Best place to shop for A/C's are Home Depot, Lowes, Sams Club, B.J.'s, and Cosco they buy in large volumeusually give a Good deal I've seen 5000 btu units as low as $89.00
Just don't drop the unit out the window when installing it
From the second floor it will void your warranty. LOL
Good Luck Phil

My son plugged in your AC adaptor Model AD 126 when we got Verizon DSL and he put the modem in my room. Cords from that modem go to my computer and to 2 other computers elsewhere in the house. The adaptor...


Too much things is connected thru that wall. The outlet is being use to pull more current that its normal use or that it can handle hence running different ports hot which will cause problems in the near. Somthing will get too much current & blow up !

Recommend that you chose a outlet for the adapter.
