I have a problem with split-type ac unit, when the unit stops due to cooling, the unit doesnt turn on to cool operate again. I have to set the control to start the unit again. Someone recommends me to change the capacitor of the outdoor control unit. Or maybe I have to replace the a/c unit?


First of all I would change out the thermostat since you say you have to turn the unit on at each use. The capacitors only assist in the start of the compressor and fan. You main issue seems to be the activation after the unit has been off. I thin ... Carrier BCA101R Air Conditioner

Any help would be helpful at this point.is there a reset switch or anything I could do to troubleshoo


100 degree temps/high humidity puts an extreme load on air conditioners - but if everything is right with the AC - 'overheating is not a big problem.\015\012\015\012The first thing I would check is whether or not the compressor is running ... Weather King 10AJA4201AH Air Conditioner

Fedders Model No. A7U12W2A-A, 12000btu airconditioner. The unit has been cooling satisfactorily for two to three years. Today the unit was cooling and suddenly there were a couple of reasonably loud knocks and the compressor stopped cooling. The fan continues to run. In about five minutes the cooling comes back on. The compressor runs for abut four minutes and shuts down. Earlier today we had a power dip without losing all power.


Hi, the power dip when translated means low current actually affected the relay starter which is situated beside the compressor. Now the relay starter works and stop intermittently which is why the Compressor cools whenever it works and does not cool ... Fedders Air Conditioners

Hello, I have a Ruud 10 seer unit in the condo i rent...it frequently stops cooling. The fan inside never shuts off, but the unit outside won't come on often enough to cool to the temp on thermostat. When the A.C. guy comes all he does is drain some water from the inside unit and it works fine for awhile. Can you explain how I can do that myself...as it's very hard to get him here. Thank you.


It sounds like the air cond is freezing up, and as he melts the ice off he evaporator coil you will have air flow again. When the evaporator, (which is the coil that absorbs the heat from your condo) is frozen over, no air flow can pass through it. ... Ruud Matching Split Air Conditioner

I have a Friedrich 13,500 BTU WallMaster. The air conditioner stops generating cold air and seems to use the fan only on a regular basis. The front panel shows that the unit is still in cooling mode but the the unit just blows out warm air no matter how low I set the temperature. Then out of nowhere the unit will start cooling again. I know the problem is not the filter. Does anyone have any ideas? Thank you.

Amana Cooling Condensing Unit fan stops spinning after 15 mins

My LG art cool units stop frequently and show a code of C8. I turn the unit on and off again and then works until the next time....This has been going on for several years now, is annoying/concerning, but each time I have a professional come to visit they tell me the same thing....that the C8 means the internal fan is blocked, but if by turning it on and off the problem is solved then the fan is not really blocked and I should not be concerned.

Americool WAM18 Single unit (heat/cool); operates perfectly well except that lately it started displaying an E5 error code every now and then and naturally stops cooling. Switching off and ON again generally clears the problem, but sometimes it will stop again for the same flashing error code E5. When it runs well, it really cools fast and is very efficient; has been installed since 2000 (13 years, yes!) - never had problems before this one.
