Question about Heating & Cooling

Why does the compressor run only for about 5 minutes then shut off, leaving the fan still running?

Blowing just regular fan air. The pressure line bigger line is not cool and smaller line is not warm and blowing not warm air over the top of the condenser unit when the fan is running

If the compressor runs and those copper lines don't change temperature, then the compressor stops, it's telling you it is low in refrigerant gas. Some a/c units have a low pressure cut out electric switch as protection.
If the unit is low in gas, gas has leaked out and usually leaves a wet oily residual where it leaked. Hopefully leaked out of a service port where the service cap was not replaced or tightened and just needs to be capped properly, after recharge of course.

It seems that you have a system short. You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset.

If this doesn't help I would recommend calling a ac service company.

SOURCE: Compressor starts and doesn't stop

Relay for the compressor may be stuck ( Contacts welded) both the fan and the compressor should operate at the same time. Have the relay(s) checked and possibly replaced.

SOURCE: Carrier Air Conditioner, cool air then runs luke warm air

Have you checked the freon level in this unit? If you are low or there is a leak it could be the problem. Hope this helps.

SOURCE: Bryant Legacy Line air conditioning not blowing cool air..

Your outdoor condenser is in heat mode. Check the wires on the thermostat. Sounds like a small wiring problem and nothing else. Good luck. Please keep me posted as to you progress.

SOURCE: RV air conditioner. Compressor running, fan stops before cool

The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.

SOURCE: Blowing hot air, compressor not kicking on, just fan ? ?

are you speaking of the outside fan or inside? compressor should be a little warm but not boiling hot. the unit could be low on freon. if low it will run a while but the compressor will overheat and shut off leaving the fan running by itself ouside. if nothing outside is running check power. if you have power check the contacted outside to make sure it's pulled in. contacters are bad about going out on goodman untis. Also ants can get under contacts.

Someone will need to find out if the compressor clutch is failing, or if it is loosing power due to a pressure switch or other problem.
A faulty relay or switch could get hot and switch off power to the compressor.

My air conditioner has stop working its blowing air inside but the fan is not spinning outside .....


If the fan is not running is the compressor not running also...if neither is running the possible reasons are 1..no power to outside unit...2..bad contactor on outside unit.is this buzzing if it is this indicates no power...3 bad capacitor,do both compressor and fan humm then quit humming and hum some more...4 high pressure switch has shut unit down because fan wasnt running if compressor was running but not fan....if your unit has this there will be a manual reset button where the lines come out of unit...if compressor was running and fan was not...1 bad fan...2 bad capacitor.. if you do not have any electrical knowhow i would recommend calling a hvac tech to come and fix unit...Thanks

Compressor will not stay on.


very good possibility that it is low on freon. If indoor unit is blowing ambient air, not cooling is happening. If this is the case and you are sure the compressor is running and then shutting off, the compressor could be overheating and the internal overload is taking out the compressor. If outdoor fan runs and compressor runs, probably cause. If capacitor is bad, unit would most likely not run that long. While unit is running, feel the large line at the condensing unit. If it is cold, and stays cold, could be something else going on. If stays warm, most likely low on freon.

My ac comes on in my RV and runs for a about 15 minutes and then the fan shuts off and finally the compressor shuts off. this happens before reaching the cooling temp. When it comes back on the fan does...


The Fan topside , Is the one working? The one that blows on the condensor? If not, your compressor can be trying to start against high head pressure. Ck the other fan, not the one that blows inside, the other one.It cools down the condensor and if the pressure is too high it will hinder the compressor. Good Luck

PROBLEM WITH MY AIR CONDITIONER


Is the outside unit running? if so can you feel warmer than outside air blowing from outside fan? If not your system may have a leak and pressures low. You can also check the piping to and from the unit larger one should be cold small one should be warm

Problem with the thermostat?


I am not sure what kind of air conditioner this is, but it is possible that it is low on refrigerant. This would cause the line to begin to freeze. When the line starts to frost over the anti freeze protection will shut the compressor off until the frost goes away. Then the compressor will turn back on and begin the same cycle until the refrigerant levels are corrected.

Thermostat ?


The Air conditioner are good only the adjustment of thermostat are the problem, select the thermostat in lower #3 you observe the thermostat will off in such time temperature reach to #3 If you full adjustment the compressor will not off.
In fan selector the compressor will autamatic off because no connection attached fan only .
