Air condition motor not going on


check to see if the fan is running if not it has frozen up over the winter. turn off fuses to a/c unit then try to turn fan by hand,if not soak down fan bearings with penetrating oil like PB Blaster keepmoving fan blade back and forth until it spins freely. Then try turning on the power to a/c unit if motor then turns fan freely , shut it down again and use a good coat of a-1 motor oil (ELECTRICAL) on the fan brgs. This should get you through for another year or so. On the other hand if fan will not spin by the motor now but spins by hand then the fan motor is bad.

How soon after replacing the condensor fan, is it supposed to kick on?


Condensor fan should start when the compressor starts. If the condensor is hot at top and bottom, turn the refrig off and check the fan for power, should spin freely by finger, and coast to a stop.
Good Luck,
Bill

My condensor fan and compressor on my Carrier AC (Model# 38ckc036350) stopped working, so I replaced my capacitor and they both work fine now. The problem is my house won't cool down. There is c


Often after a repair has been made, the air conditioner will take hours to readjust back to normal. When the system has been off for to long, not only does the heat in the house rise, but so does the humidity, which has to be pulled out of the air first before it really starts dropping in temp. You could have a low charge on refrigerant, dirty filters, etc. More than once I have ran into things that were just coincidence after a repair that showed up. Since you just replaced the capacitor, I would make sure the fan motor is turning in the right direction and there is nice air flow coming out of the condenser, some times if one wire is wrong, it can cause it to spin backwards, which will work, but just barely. The air needs to be pulled through the coils, not pushed. Hope this helps!

When i turn the A/C on, the temperature begins to rise and it begins to spill the antifrezze from the radiator reservoir. Dont know what the problem is.


You evidently have a problemwith your engine cooling system. Check to make sure that the cooling fins on your A/C Condensor and Radiator are not clogged up with dirt and debris. Check that your mechanical fan clutch has some resistance to pushing it by hand. If it spins too freely. the fan clutch could be worn out. Check to see how much air it is actually moving through the radiator. When the engine is at operating temperature and the A/C is on, This fan should be turning at a very high speed and blowing HOT wind in your engine compartment. I believe that your vehicle is also equipped with an electric cooling fan. The electric cooling fan should be running any time the A/C compressor is engaged. If not, then you must diagnose this failure.

38CKC060 Carrier. Outdoor unit-fan does not spin, noise and very hot inside the cage!


It sounds like your fan motor is burnt up. If the noise you are hearing is coming from the motor itself, then it's going to have to be replaced. One way to check this also is to turn the unit off and try to turn the fan blades by hand, if you cant get to it, then use something skinny and long enough to drop through the opening on top. If there is any resistance, than its difinitly a bad motor. If the noise you are hearing is coming from the compressor, then your fan motor still might have a chance and only needs a capacitor which is a round or oval part inside the units electrical compartment. Depending on how mechanically inclined you are, it is possible to fix these yourself. Just a warning though, if your fan hasn't been running and the compressor has, it can or could burn up the compressor also. This is another reason why it can be hot inside the cage. Your compressor will go into internal lockout if it gets to hot and will not come back on until it cools, but it can only handle so much. Hope this points you in the right direction and good luck!

Carrier Compressor Issues?


When you shut it off and back on it slugged the compressor if you turn it off and back on before the pressures equalize between the high and low sides it will slug the compressor and it will not run should let sit for five minutes or so before restarting. The humming is either the compressor making noise usually common for the compressor to make some noise or the fan motor bearings are getting bad on the outside unit. If the unit works normal probably not much you can do till it breaks if it is the compressor it is more economical to replace the whole unit if it is just the fan motor it is worth changing. You could take an amp draw on the fan motor and the compressor to see if the are within the limits on the name plate of the outside unit.

Condenser fan is not running. coils are hot and the compressor sounds like its working. the evaporator fan is working. The refrigerator is not as cold as it should be


Spin the fan by hand and see if that helps. The condensor fan is causing head pressure to rise and the compressor is fighting it. This in turn will affect the cooling effiviency.Vacuum the cobwebs and dirt that has accumulated and vacumm the fan motor yhrough the vent holes on its end opposit the blades. Spin the fan blades with a pencil to protect your fingers. If the fan still won't turn, it may need to be replaced Good Luck_Ned_

Carrier fa4anf024 blower is not working. Pipes are getting frosty so the compressor must be ok. I hear 'gurgling' from the air handler, but no fan


you can remove the top panel by removing the 5/16 screws his will gain access to motor turn the power off to the unit and check if the motor is hot. if it is let it cool and retest if the motor makes a loud humming noise and does not turn try to manually spin it if it starts up you have a bad capacitor if it wont turn it is seized and the motor will need to be replaced . If it cold and makes no noise you may have a bad blower relay, you will need a volt meter to test. that motor is 240voltmotor

2 year old Coleman Mach III tapping and not blowing cold air:


Make sure the condensor fan is blowing through the condensor on the roof. It sounds like the compressor is fighting high head pressures after running a bit.. After so many attepts, or if it suceeds in operating the load trips the circuit breaker.. Make sure the condensor is clean and air is passes through it from the fan. Just for clarifiication the condensor is the coil that gets hot and the evaporator is the coil yat create the cold air. Good Luck, and if you will, let me know how it turns out. Good Luck. Ned

Ac fan not turning on I can ''stick start it'' but which direction?


The condensor fan should be sucking air from the top and blowing it through the coils, probably a counter clockwise direction. The buzzing/humming sound is confusing to me. A humming sound sounds like a motor that can not turn over to start. A starting capacity would be needed. Just because you changed it out last year does not mean it is good. A buzzing sound sounds like a contactor problem. Contactors buzz and after a while, they will fail. In any case, you can "stick start" the condensor fan PROVIDED you are sure the ac compressor is working (this is for a short and temporary use). Also, you may have a high load duty capacitor that assists in the unit running. This will affect your condensor fan operation if it is not good. Unless you know all the components and operations of ac electrical, I would highly recommend calling out a professional.
