My central air conditioner works perfectly and cools the house just fine, but the fan outside repeatedly turns off/on?

Not at a normal level either. It will typically run this way: Turns on for about 15 seconds, "CLICK" turns off. Turns on for another 15 seconds, "CLICK" turns off.

It keeps doing this while the AC is running. What could the problem be and what should I do, if anything, about it? Again, the AC works great, it does not affect the cooling of the house.

Is it supposed to do this? I've only owned the home for 22 months and I rarely use the air, but it has done this since I moved in. The Manufacture is Carrier and this is the model/other info on the side:

They do not diagnose problems when you call customer service, they recommend you get the unit serviced. I want to know if it is necessary, or if I can fix it. Asked by dwdrums 41 months ago Similar questions: central air conditioner works perfectly cools house fine fan repeatedly turns Home.

You probably want to get that checked out This is simply my opinion but it sounds like you have a problem. Now you say it doesn't affect the air coming out the other end so it is possible to ignore it but in my opinion you will just wear out the fan motor that much faster having it turn on and off like that. In my experience with air conditioning units the fan should stay on or be off for a while.15 seconds is just too short a duty cycle.

Either a wire is loose (not likely since it seems to switch properly with a click sound) or perhaps the thermostat (temp sensor that controls the fan) is faulty. Since you have only been living there a short time is it possibly still under warranty? Or has it been installed since a previous owner?

If under warranty you should get it checked out. If not you'll have to make a choice. If you can live with it and don't mind risking blowing the motor early, then leave it alone.

If you're handy, take a look yourself. If not, get it checked. Good luck!

Just to let you know in california pg&e set up satalittle boxes on the out side condensors, when theres alot of useage of electricity, they can remotley turn off your outside unit for 15 minutes every half hour so you still have circulating air but the condeser is off the it will come back on ....its normal .

1 Hmm. Usually, the fan on the outside unit runs only when the compressor is on. If the fan on the compressor is turning off while the compressor is running, there's potentially a serious problem, since the compressor can overheat.So... what do you mean by "the AC is running"?

The compressor, or the house fan? Is the house fan set to ON or AUTO? I suspect that the most likely problem is that your thermostat control is getting old.It's what turns the AC unit on and off, and that controls whether the outside unit runs.

My first thought is that the thermostat is turning the AC on and off, and it's really not supposed to do that. It's supposed to be damped a bit, so that it cools the house for a while, then lets it warm up for a while. You can get an effect like that when you've got a compressor that's too big for the house.

The AC turns on, dumping out a burst of cold air, and then shuts off again. But I don't think that could cause it to happen every 15 seconds.So I'll hold off taking up an answer slot until I get more info, but I bet it's the thermostat. Is it a digital thermostat?

(If not, you might want to get one. They're not expensive, and easy to install, and lets you do fancy things like automatically raise the temp during work hours when nobody's home. ) .

2 Air Conditioning (A/C) CompressorAir conditioning compressors are an integral part of the refrigeration cycle that cools your home or business. A/C compressors do just what their name suggests: compress cool Freon gas molecules into hotter, high pressure molecules that are then transported to your air conditioner's condenser, which is in charge of cooling the gas into a liquid. Your air conditioning unit's ac compressor is the origin of the refrigeration cycle; without this air conditioning part starting the movement of Freon throughout your heating and air conditioning system, yourair conditioner would be just a metal box containing a fan, with absolutely no cooling capacity.

If you suspect a problem with your air compressor, contact your local air conditioning repair technician; in general, compressors are complicated pieces of machinery that should be examined by a professional. To locate your central air conditioning system's compressor, look outside in your air conditioner's outdoor metal storage unit for the large box with no apparent moving parts. Occasionally, compressors will make unusual noises, which are usually due to a loose connecting rod, piston pin, crankshaft, or other internal air conditioning part.

A "hard starting" compressor may stutter on, then stop, then restart. Both of these issues may require replacement compressor parts, and should be diagnosed by a qualified air conditioning repair person. On very hot days, such as those experienced often in tropical climates like Tampa and Los Angeles, pressure might build up in the compressor, causing it to overheat; your thermostat will register these temperature changes.

The compressor may try to start, fail, and create an electrical overload. Resetting the high-pressure limit switch, which is designed to protect the compressor from shorting, may correct the problem. Located in the air compressor´s access panel, this switch will allow energy to flow back to the compressor.

If the compressor starts, your problem is fixed, and your unit should start normally. If the compressor fails to start when the switch is flipped, the electricity will be cut again, and the cycle will repeat itself. After several cycles, if this process fails to restart your compressor, it might have shorted its internal components.

This issue requires professional attention; unplug your air conditioning unit and contact your local air conditioning contractor. An air conditioning technician will be able to locate the appropriate air compressor parts, or replace the compressor all together. Often, a broken compressor will prove fatal to the heating and air conditioning system, because the cost of replacing the compressor exceeds the total cost of replacing the air conditioning unit.

Of course, proper maintenance of your compressor and its related air conditioning parts will help your home air conditioning run at peak performance. Your compressor, which is located outdoors, can be cleaned with a hose. Also make sure that no leaves or debris collect around the compressor case.

During the winter, the compressor should be kept covered, in order to protect its parts from snow and ice. Attention to air conditioning filters and air conditioning coils will ensure that dirt, debris, and allergens do not circulate throughout your ducts and end up clogging your compressor.

What are the causes of humidity in the central air conditioner.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
