Having problems with your Air Conditioners ?
Outdoor unit does not Run
If you manually push in the contactor does the compressor start? If so, then it probably is the defrost board. If not, then do an ohms check on the compressor to make sure it hasn't failed.

I have a Sanyo Split System the indoor unit is a KHS0921 and the outdoor unit is a CH0921. When i first turn the indoor unit ON the fan will run for a few minutes and then go off. The outdoor unit never comes ON when there is a cll for cooling. The only way to get the fan to come ON again is to turn the breaker OFF and then back ON. The Operation loght will come ON when the fan is running but it will start flashing when the fan goes OFF. What should i look for?

Even I turn of the indoor unit via the controller , the outdoor unit is still running. I turn off the breaker and turn on still the the outdoor unit still running. What do you think the problem is?
Usually when this occurs it is a contactor burnt shut. If left to run, it will freeze the outdoor condensing unit into a block of ice. The contactor activates the compressor andfan and the contactor is controlled by the low voltage from the th ... Frigidaire Air Conditioners

I hope this is help full cheers andrew
My gut says that this is evidence of a bad control board(circuit board). As usual, double check that your batteries are good in the thermostat. I have seen some weird things happen when the batteries are low. This one may be a job for your local con ... Sharp Air Conditioners
Compressor problem? My outdoor unit comes on with the fan blowing just fine. Then I hear a buzzing sound for about 2-3 seconds which I believe is the compressor trying to come on. (Incidentally, a couple of lights inside the house seem to dim at the same time that the buzzing sound occurs.) The buzzing sound reoccurs every couple minutes while the outdoor unit fan and the indoor blower both continue to run. I have shut down both the outdoor and indoor units for a couple hours and tried restarti

AC Starts normally but after some time of coolinf compressor in outdoor unit trips. Compressor running light in indoor unit remains on and outdoor unit fan remains on. But no cooling. After a break of about one hour AC works again and problem repeats.
Probably overheating. Check the outdoor coil and see if it is stopped up with dust, grass etc. If so, disconnect power to the unit, and clean the condenser coil with water or air. Be careful not to bend the fins if you use a water sprayer. ... LG Air Conditioners

My indoor unit on my heat pump will not shut off. The electric heat keeps running, and the fan keeps running. It only happens when it is really cold, like 25deg or below, above that and it functions fine. The outdoor unit shuts off, but the indoor stays running. I do HVAC work, but I have never seen a problem like this. I have switched the stat out, and its just so strange. I figured the relay may be stuck, but if I turn the stat off, it turns off shortly after which tells me it may not be the c

I purchased an Amcoraire split system unit for my 2 story garage. Licensced electrician did the wiring and licensed HVAC co. installed the 2 indoor units and outside unit. Outdoor unit is Model # AOM 243 HX 24000 BTU Indoor units are both Model #AWM123 HX, 12000 BTU each When I turn the unit on, it runs for about 60 seconds and then I get an error code on the inside wall unit that says P7. My manual says this has something to do with voltage. I had the power company come out and they show the
Since the manual says the error code has something to do with voltage it means the voltage is either too high or too low. And as the electric company says the voltage is within limits the the error is as a result of the voltage fluctuating. All you h ... Amcor Air Conditioners
Hi, We have two Paragon split systems which effectively cool our large home. One system is playing up. It started 3 days ago where there is water dripping from the front of the unit and the green 'run' light is now flashing. I tend to think it's blocked somewhere, buy my husband cannot find where to check this. Our outdoor units are both under the house with very effective ventilation but the last 3 days have been extremely humid, however the other system is running perfectly. Any ideas? Thanks,
More then likely the blockage is inside the a-coil section. At the drain. To get to it easier remove the pvc drain line. As the drain line comes out of the collection pan it goes into a pvc line the 90 degrees elbow goes to floor. So cut the lin ... Air Conditioners

Not a GE unit. I charged unit with refrigerant and powered up unit. After running for @ a minute it shut off, having no power light at all. I found a set of wires reversed that were going to the outdoor unit. after fixing the wires i can't get the unit to come back on. The breaker is not popped and I assume there is some kind of fuse or overload that I have to manually reset or replace. It is a chinese (i think) made unit Air Control
Since most of these units, come precharged for line sets up to 125' in some models, the fact that you charged it, concerns me.
