That was real deep diagnoses I'm betting the outside unit is the problem. check the outside for240-volts to the contactor if not backtrack for the lost voltages and remove the outside cover to check the little silver can (capacitor) for swollen at the top terminials, due to power surge.

Ruud UAKA-030JAZ fan spins, not blowing cold air


there are 3 things to be considered,first,if the compressor motor `s connectors are having loose,it gives a hi ampere to your RELAY that can cause to its contacts being fried,second,the compressor motor itself is gaining a hi ampere already i.e. having unusual sound that can cause heavy friction inside the turning mechanism and third the last but not the least,maybe this time,the tubes or the compressor itself having very small holes that causes to the refrigerant to escape and it doesn`t gives off cold air.

I moved into a place that has a MasterCool Evaporative Cooler on the roof. The ownstairs is quite comfortable so I really only need to cool the 2nd story.... it seems as if all the cold air settles...


jbrown - Hot air rises, Cold air falls. If you have ceiling fans upstairs, turn them on to run counterclockwise at highest speed you can stand. Make sure all the windows are closed upstairs. The ceiling fans will help to keep the cool air upstairs and pull some from downstairs.

If you don't have ceiling fans, invest in a box type fan that you can place at the head of the stairs (that's the top of the stairs) run it on HIGH and it will act like an exhaust fan, by pulling cool air upstairs. It may take a while, but it will help cool the upstairs to some degree.

Hope this helped you. Please let me know. Thanks.

Inside fan turns on when outside unit is in defrost mode when heat is selected. This causes it to blow cold air for about 10 to 15 minutes prior to the outside fan starting.


The inside fan will run while the unit is in defrost. The electric heat strips should kick on to help prevent you from feeling this cold air. When the unit is in defrost it is essentially running in the A/C mode. You should make sure the electric heat elements are working then go from there.

Turn the thermostat as low as it will go and have someone stand out side, they should here the condensor fan and compressor come on at the same time. They are two distinctive sounds so you should
be able to tell if the compressor is running.

If nothing happens and you are skilled with electrical
you can turn power off and remove the electrical
cover to the outside unit. Restore power and carefully
push in the contactor, if the fan and compressor
starts you have a thermostat or low voltage problem.

If just the outdoor fan runs on any attempt, more than likely you need a new capacitor.

My AC unit is not blowing cold. I have two. One small and one big . I just noticed that My upstairs was not cooling off. So I turned both units on and went out sid to check them. The small one is running...


The start capacitor is in question and the fan appears to be overheating, That is where the water camre into it. You may need a HVAC tech to make your repairs. Good Luck _Ned_

Coil and fins start ice up


The fins are dirty. They need to be washed every year or two with an acid based cleaner. They MUST be rinsed completely.

COMPRESSER IS VERY HOT, FAN OUTSIDE BLOWING COLD AIR OUT NOT HOT


Most likely the unit is low on refrigerant. You could also have a restriction in the system. You need to put gauges on the unit.

Central air


Most thermostats have a setting for the fan called, "manual". That keeps the fan on continuously. The electronic thermostats can fail in a "fan on" condition. That would require a new thermostat. I also saw one air conditioner with a fan relay welded "on" by electrical surge. That would require a new relay.

No air flow upstairs


Cold air is denser than hot air, so is harder to move. All vents have some mechanism to regulate flow, so close all of the downstairs vents. Check to see if your furnace fan motor has more than one speed, & set it on maximum. Keeping the fan on all the time will help as well. If all else fails, you may need a more powerful fan motor.
