If the AC is coming on with no air output the problem is that although the compressor is running - the fan motor is not.

This can be because of a 'switch' malfunction, a wire burnt into, a bad fan capacitor or a bad motor.

Of the four possibilities the easiest two to identify are the 'wire that has burnt into,' and a bad fan capacitor. A wire that is burnt into is obvious and so is (sometimes) a bad fan capacitor. A fan capacitor which btw - is a little module (usually gray or silver in color) with wires attached to it. I would check all my wires to it and to the fan motor and anywhere else I could in the unit. Also examine the fan capacitor itself - looking for burnt damage or a 'bulge' in the module which are direct symptoms of a bad fan capacitor.

If it's the capacitor you can remove it making sure you mark your wires in such a way you can connect them up after acquiring a new capacitor.

You can buy capacitors at any Air Conditining Supply house - and they will run about $15-$25 or less.

A bad motor is usually indicated by the motor 'not starting/running' and/or 'the motor being hot to the touch' - there's not much that can be done these days if the motor is bad but replace it. And unless you're really mechanicaly inclined and have plenty of specility tools I would not attempt it. A Service Tech is the best bet here, and you're looking at a repair bill of around $150-$250.

A 'switch' problem is really not that likely but for a nominal fee (usually around $35-$50 you can buy a switch and change out the old one. Like I said this is not likely the problem and I would probably not do this on a hunch.

good luck!

  • if the capacitor looks ok and the fan runs fine should i still check the capacitor and can the appliance place test it for me? if the compressor kicks on then shuts off immediately . it sounds like the clicking noise is coming from capacitor. I have cleaned and oiled the unit. is there a chance it needs freon? or if capacitor isnt problem should i bite the bullet and get a compressor?

    We had this same problem and it ended up being the battery on the camper.

SOURCE: air conditioner symbol defrost keeps coming up so

These will defrost themselves automatically when they need to - internal sensors. If it is icing up at all in cooling, then the charge is wrong. Units such as this are very sensitive to incorrect charge, so I would recommend that you have a qualified tech come out, recover all the freon and weigh in the correct charge. If this is a "new" problem, then a leak check/locate would be in order.

SOURCE: Air conditioner blowing only warm air

possibly have a capacitor out on the compressor side of the a/c Since the unit works and its only blowing air the compressor isn't kicking in. The capacitor boosts the compressor to activate the compressor. I would have the capacitor to the compressor replaced first before going any further.

Good luck on your repair

Intertherm air conditioner won't work

First I must ask...does the compressor come on? does it just sit there and make a clicking noise? If it doesn't come on at all and if you are handy with a screw driver and can do electrical type work you can take a piece of insulated wire and jumper the thermostat (put insulated wires between the terminals the wires connect to). If it comes on and blows cold air replace thermostat.

Hot air coming out of back

portable air conditioners mainly have two hoses one hose is exhaust thats the one that is blowing hot air. the one pulling is return.. the hot air blowing out should be exhausted to the outside. the blowing air needs a hose and to be laid out a window the back should have model and serial maybe product number. the two holes are either 4 inch or three inch and most portable units other than hand me downs come with a window frame that allows the hot exchanged air to go outside and cooler air to be used for heat exchange.
