I assume you refer to the outside fan, it is probably the capacitor, as the dual capacitor has capacitors for both the fan and compressor in one device, (loof for swelling of the case or oil around the seal) BE CAREFUL AS THE CAPACITOR STORES POWER EVEN WHEN THE POWER IS OFF TO THE UNIT! I would also verify that you have 230VAC to the unit, if you "dropped a leg" of ower and are feeding only 110VAC to the unit it will not operate

How do I remedy the problem? It seems to be related to a fan trying to start up, but takes 10 or 12 tries before it keeps running.


model # AGE ? needed to give you better detail
If this is fan at compressor area it may be wired with compressor
compressor may be kicking out on overload.
stopping fan as well Change start relay at compressor
if that don't cure it looking at compressor

HVAC fan is on, but the compressor attempts but will not start


Sounds like you have a condensing unit that has a lock up condition; commonly known as "Locked Rotor'.
A simple step would be to be sure the compressor is cool.
Start the unit, and as it try's to start, bump the compressor on the shell sideways to jar it , with a rubber mallet.
If the compressor starts... it may or may not start again at one point.
You can try adding a start assist, or commonly known as a Hard Start Kit. It's simple and the two wires go on the Run Capacitor In parallel with the wires with the compressor wires.
Usually the capacitor has a C common ..F fan.... and M motor terminals . The start assist wires piggyback on Common C and M motor. NOT THE FAN side of the run cap.

My Whilrpool AC Model number ACM102XJ0 fan is blowing air but it's not cooling.


Air conditioner compressor will not start. When power is applied to the air conditioning outdoor unit the fan starts, but you hear a sound like the compressor is trying to start, "UGGG"..., for about 5 to 10 seconds and then all you hear is the outdoor condenser fan run. The compressor is locked and will not start. What is happening is the compressor is trying to start, but because the compressor motor is locked it tries to start for a few seconds and then because of the high amperage being drawn goes off on internal overload. The internal overload protects the compressor windings from overheating and burning up. I see this many times during the start of the air conditioning season. Some compressors just have a hard time starting after sitting all winter long. Many times I can get the compressor started again without having to buy a new compressor by using the device known as a "Super-Boost." I keep two or three of these on the truck. They have saved many of my customers from having to buy new compressor

Running but no cool air blowing


Problem #1:Outdoor condensing fan motor has stopped running. This problem could be caused by a bad motor run capacitor. If your motor capacitor is not the problem, then more than likely you need a new motor. Is the fan blade tight, stiff or hard to turn? If the fan blade is hard to turn then you probably need a new motor. Problem #2: Air conditioner compressor will not start. When power is applied to the air conditioning outdoor unit the fan starts, but you hear a sound like the compressor is trying to start, "UGGG"..., for about 5 to 10 seconds and then all you hear is the outdoor condenser fan run.

The freezer acts as if it is going to start, but then it doesn't. the fan inside is running, but the temp is up to over 40 degrees


When a compressor is burned out it will try to start and then quickly overheat and kick out on the safety. Listen closely to the fans when the compressor tries to start. A bad compressor will pull so many amps that the fans will actually slow down until you hear the click, then the fans will pick up speed again. If this is the case you will need a replacement compressor. Let me know how long it takes to click out when it tries to start.

Not cooling, compressor and condensor coil fan not running.


It sounds like you may have bad starting components on your compressor. I would check your condenser fan motor for 120v. Or try to put a small box fan behind the ref blowing directly on the compressor to aid in cooling it. If the compressor kicks in then you know the problem is with your condenser fan motor and not your compressor. If the start components are bad you will usually hear a clicking noise from the compressor every 10-15 mins or so.

Hope this helps _MJ_

Please help our ac compressor wont come on


Hi, did you change, capacitor for compressor too. check compressor overload switch,(relay) normally located on compressor terminals, (where you connect wires to compressor) that's the device that goes klix when compressor goes to start, could be faulty, or maybe low voltage from your mains(house panel) check line voltage, with digital volt meter, some compressor won't start if voltage drops to low, yes fan will work, could also be, your compressor has a lock rotor, (hard start), you can buy a compressor hard start kit, from appliance store, and try to start compressor, or maybe compressor internal winding, are damage, especially now in summer, when you got a lots of voltage drops, check compressor winding, check compressor winding for short circuit, remove cover on compressor, remove 3 wires from compressor terminal, use ohm meter, put one tester lead on copper tubing that's connected to compressor, and next lead to compressor terminal, one by one, if you get beep (continuity) from anyone of those compressor terminal, you got a short- circuit in compressor, you will have to replace compressor, but if there's no short, them try hard- start kit, replace overload relay, you will see it at compressor terminal location, after you remove cover. good luck.

When unit starts the condensor fan only comes, not compressor


You need a new fan motor and the correct capacitors for your sydtem I think they are 35 or 45 5 cap. Try a hard start kit on compressor. Are you sure you have the cap wired correctly?Russ

Turn the unit on, the fan runs, and when the compressor tries to start the fan slows down and the compressor will not run. After a few seconds the fan speeds back up. I put an amp meter on the compressor...


sounds like you have a bad capacitor, if it's not tripping the breaker it doesn't sound like the compressor is drawing LRA unless the breaker is oversized for the condenser.
