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?

A mate has a fujitsu ast24rba-w, the outdoor unit runs but the indoor fan won't go. Found indoor board buggered so I replaced it, fan still no go. Got hold of a fan that I know works and still won't run!! Checked the start capacitor and that meters ok. It won't even run on fan only. From what I can see the fan should run, there is nothing left to replace. Any advice would be greatly appreciated!!!

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 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

I have an LG mini split ac / heat pump system ( LAN096 ) that is only 4 months old was working great in all ways until suddenly it quit heating. I am sure it happened quickly because I was nearby when very warm air changed to cool ( unheated ) and hasn't heated since. When I shut it down and restart it the indoor fan runs right away, which is not normal and the outdoor unit will run for a minute or so then shut down and stay off. The indoor fan will continue to spin as though it is set in a 'fan

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

Indoor unit freezes up, turn the mode button to the fan only to thaw out the indoor unit but the outdoor unit runs, What should I look for?

If the outdoor unit is not shutting off, your indoor coil will freeze up when the thermostat "satisfies" and shuts off the blower. The most common cause of a non-stop outdoor unit is the contactor. This part is usually black or brown in color. The li ... Air Conditioners
