Re: fan is not runinig
Check the fan motor. make sure that it spins freely and the shaft doesn't wiggle side to side (in and out wiggle is ok) after that check the run capacitor for the motor. It takes a special tool to check a capacitor you might need to call an a/c service to do this for you. also check fuses and circuit breakers, sometimes only one fuse will trip and not the other
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Hi David, I'm glad to help. 3 Things could be happening here. (1) There could be air trapped in the cooling system somewhere, which you can remove with thye bleeder screw near the thermostat housing. Try this first. (2) The cooling fans may be trying to go out for the radiator. The next time the problem occurs raise the hood and see if the cooling fans are working, if not replace the cooling fan module from the dealer. (3) Blown Head Gasket. This is not very likely because you say it happens ever few days and if it were a head gasket then it would happen after running a few minutes everytime. Hope this helps and have an awesome day David.
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.
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.
so its obviously an air con? are you running in automatic mode, if so that can be a problem as automatic yes is a good idea to maintain a set temp but it goes from heating to cooling so you heat an area and t/stat says its too warm turns heating off then goes over set temp so its starts cooling usually that is to do with the location of t/stat and set out of heater but automatic is useless and really is only good for offices where its not noticed like your own home, i tell people not to use automatic but set the control to what you want so if its cold you heat if its hot you cool you don't need both tassie where i'm from has four seasons in one day but i still don't think you need to heat and cool in one day the only place in the world that has such major condition changes is the sahara desert where it'l cook you during the day and freeze you of a night so if my assumptions right and you are using auto function DON'T. use what you need to either cool or heat your house not both in the same day it doesn't make sense and yes you can run it all year long on auto but its really not worth paying to run something you don't really need!
If the induction motor ain't going I would look for a blown 3 amp (purple) fuse on the control board. If that was good I would check if any of the roll out switches were tripped. If a rollout switch was tripped check or air restrictions somewhere.
If the outdoor unit isn't coming on then you need to have a tech come out and check that the unit is being called to come on. If not, then you need to check that the tstat is calling for cool. If it is then there could be a short in the wirning to the ouside unit. If it is being called to come on and the outdoor unit's compressor is kicking on but the fan motor doesn't, then it could be as simple as a capacitor or the motor could be bad. Either way, it sounds as though you may need to call for a service professional.
Try the following to begin operating the air conditioner:1. Plug in the air conditioner. (To prevent electrical hazards, do not use an extensioncord or an adapter plug.)2. Set the exhaust vent to the CLOSED position.3. Press “On/Off” button to turn unit on.5. Press Mode “COOL”6. Press “TEMP/TIME” up or down V to the desired set temperature.Review the “Air Conditioner Features” section for other settings
