Ac unit turning off and on by its self

We have a carrier (brand) ac unit in our office that is shutting off and on by it's self. It has been doing this for two weeks or so, we have put in a work order but no one has come yet so we are trying to see if there is anything we can do ourselves. We were not able to find the manual on-line. We are in Iraq so it is hot and our ac is very helpful. If you can help us discover the solution that would be very appreciated. The model number is 38qg24h.

I ran across a unit that had a very similar problem, everytime I would go to look at the unit it would work fine, but later it would stop working. What I found was the door on the evaporator (inside unit) was loose and not mating up well with the door switch. If the door or switch has vibrated loose the problem will be off and on. This may be even more of a possibility if the unit has been serviced recently...

I am thinking that you could have a low refrigerant level. there is a low pressure switch that is being triggered and as the compressor cuts off, the pressure will go up and run again the compressor.

immediate solution, have it charge to the proper level for the mean time but it would go back to the same thing as the level goes low again.

permanent solution, find the leak, repair, and charge again fully with refrigerant

refrigrant wont get low without a leak.

tnx for using fixya,

How to troubleshoot Carrier AC Split Type? No air flowing

If this is happening in both heat and cool cycles, it is most likely a fuse or capacitor. Split AC units usually use 2 capacitors one for the compressor motor and one for the fan, these are usually 450 to 500 volt AC and some times when one has failed the system still tries to run as normal but soon shuts down after a few seconds as the lack of a complete cycle is sensed. These are located in the outside unit under the cover and can be tested with a small circuit tester but BE WARNED if the capacitor is working it will hold a potentially lethal charge and must be shorted out with a metal object before removal to discharge it, do not attempt this if you are a novice. Replacement capacitors are easily available from $10.00 to $120.00 depending on type, brand and availability. An AC serviceman can do this for you for around the $600.00 mark.

Carrier ac keeps turning on and off

what is the temp. outside ? If it is doing it when its hot out clean the coil outside could be tripping on high head pressure. If its not make sure the inside fan blower is turning.If its not it could be tripping on low head pressure. If it only runs a short time you probably have a low charge.and it is causing it to short cycle.

AC Condenser motor will stop at 1pm but inside unit is still running but no AC. If I turn the AC unit breaker unit off and then an hour later turn it back on. The unit runs fine all day until 1pm. Had a...

Hi, the tech should have been able to figure the stat out with out a manual to see why the condenser is shutting off at 1:00 P.M. This is unusual for this to happen, unless it was winter and this is a heat-pump going into defrost, but just the fan would shut down. Does this unit have a box on it that was installed by your electric company that shuts the unit off during high peak conditions in the summer? This would cause it to shut down at the same time everyday. If not, it would have to be something in the thermostat that is set for it to shut off at that time. It still does not make since, as it would shut both the indoor and outdoor unit off, not just the condenser. Are you saying that just the condenser fan motor is shutting off, but the compressor continues to run until it shuts off on high head pressure when the fan stops, or does the complete outdoor unit shut down fan, compressor and all at that time??. It sounds to me like this outdoor unit has a time delay relay that has a fault in it may be shutting it off at this time daily? Please let me know if its just the condenser fan motor that shuts off, or if the complete unit is shutting off all together, this will help .

The outside fan may run if the unit is in defrost mode this is normal for most heat pumps it is there way of trying to keep the outside unit from staying iced over so the next time the unit runs it will have air flow through the coil and the ice will not be there to prevent air flow.

My Carrier AC fan will not turn, only blows out warm air.

Breaker has popped either at breaker box or at the safety shut off switch. Fuses are blown or the sending unit has popped.

Compressor not doing much

I am assuming that you are talking about a central ac unit. On a central air unit the outside fan must be running whenever the compressor is. If it's not the compressor will shut off from overheating withing minutes. First you need to shut off the unit for several hours and let it cool completely down. Then turn it on briefly to see if the compressor starts and see if the fan tries to start.( I am assuming the compressor starts and runs.) If the fan won't start try testing the capacitors. There are usually two one for the fan one for the compressor. Sometimes there will be one combo one. Mark the wires and remove the capacitor. Get it tested and if bad replace it. This will probably do the job. If not test for current at the fan motor. Also test to see if it turns freely. The motor may need to be replaced. This will run about $50. The capacitor should always be replaced when the motor is changed anyway.

Sounds like your indoor fan motor is not working, check either the cap or the indoor fan motor it's self.

Carrier Weather Maker not blowing anything

if you turn on just the fan at thermostat does it run.
if not then the fan motor / belt / relay / start capacitor is the issue.
if your not familiar with ac then you will need help to diagnose the air handler.
belt is easy.
just take a look by opening the side access panel
