SOURCE: Carrier Synergy 2000 Condenser fan does not turn on

the mfd is stamped on the side of the capacitor.Be careful to kill the power and to NOT touch the terminals.The capacitor is capable of holding a charge even after power is disconnected.

SOURCE: Outdoor fan motor is not running fast enough?

Thanks for the suggestion. I figured out the problem. The replacement fan motor I bought was general fan motor. it had 5 wires. Two of them went to the capacitor (this unit has combo capacitor, 3 leg). I followed the schematic diag on the motor and connected one leg to the C and the other leg to the FAN on capacitor. what was happening, the start winding was working against the run winding in the motor. Once I switch the wires in the capacitor, fan ran at full speed. thanks again for your reply.

FOR QUESTION 1: They do run independantly. What will happen when your compressor is running but your outdoor fan does not, the pressures in the system will go really high and compressor will overload. That outdoor fan is used to disipate all the heat that is transferred from the inside to the outdoor unit.
FOR QUESTION 2: If you hear humming it can be 2 things. FIrst one is that that capacitor went bad. Dependiing if its a dual run capacitor(which helps both compressor and fan motor) or they both have individual capacitors. The second would be a bad fan motor. OPen your service panel outside to the AC. Find your capacitor for you fan motor. if there are 2 , locate the one that goes to your fan motor. Check it out(if its blown physically youll will notice it like really bubbled, like swollen) then change itout. Or you will have a dual run capacitor that runs both compressor and fan motor. It will have the terminals marked (Fan, Common, Herm) Bsically check your capacitor mfd(micro fared rating, it will say on the capacitor what its rated) Get a multi meter and put in the "MFD' selection. Before you check any capacitor you have to discharge the the voltage charge it has. Use an insulated handle screwdriver and just place the metel part across the capacitor leads. Basicall short them out. Then proceed with checks...hope this helps( remember to always pull the disconnect out from the box outside to cut power)

SOURCE: home ac compressor fan won't turn all the time.

your looking at $175-$225 for just the single phase motor depending where you purchase, I just replaced mine(identical unit) due to screaming dry bearings, if you replace it your self make sure to keep new wires tight along side of unit or fan will cut them if loose and its a fan- 5mfd/25mfd compressor@440volt cap

Air is cold. Compressor outside works. The condensor will run for a little while, then shut off while compressor is still running.


Outdoor condensing fan motor has stopped running. This problem could be caused by a bad motor run capacitor. purchase a new 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.bobicehouse_96.jpg

Fan dont work but when i turn on cooling system two fan work please give me lay out for cut-off and fuse


If you have two electric fans the fan on the passenger side of the vehicle is the radiator cooling fan, that fan should run when the motor gets to hot. The fan on the driver side is the ac condenser fan that fan runs only when the a/c is turned on. The only time that both fans run is if the a/c is on and the motor or coolant is above normal tempeture.

I have a 1998 jeep grand cherokee 4.0 4x4 it is running a little hot, the air cooling is not good, as I inspected the water, it was rusty and milky. do you think I need to replace the thermostat? oR JUST A...


Several things may be the culprit:

Fan relay - this tells the fan to turn on when the AC is turned on - $50 part DIY
Thermostat - should be in the front of the engine on top with hose running to it - $9 part DIY
Radiator Fan shot - u can replace the fan motor for about $100 DIY
Coolant temperature sensor - tells the fan to kick on when the coolant gets to a certain temp

While the engine is running and warmed up, lift the hood and listen or look to see if your radiator fan is running (the fan should kick on around 190-210degrees) if not, turn on the ac and and see if the fan starts running, if not, your fan motor is bad

Hope this helps

My coolant is not working? when driveing it stays cool but as soon as i stop the fan dosnot kick in ad i over heat?


The coolant is working well, because the engine stays cool while driving. The problem is the fan relay, fuse, or the fan itself. Do you have AC? If so, turn it on and you should have instant running of the fan. The normal operation of the fan is: the engine thermal sensor tells the computer that it is getting hot which in turn tells the fan relay to turn on and that is supposed to turn on the fan itself. The fuse protects the high current wire to the fan. Try to turn the fan blades by hand--if stuck or very hard to turn, replace the fan motor. If you can't find the fan relay in the fuse compartment, it may be a solid-state device that is located near the fan motor. Chase the fan wiring back to the relay. Hope this helps!

Condenser fan running backwards on heat pump


I am having the same problem, sometimes it runs in the wrong direction, blowing the air down. Sometimes something gets tripped and I need to turn the thermostat to off and wait a bit then restart it. If I am lucky it will run int the correct direction and also will warm the house. Sometimes it send nothing but cold air to the house's forced air.

Air compressor kicks on but fan doesnt and vice versa


I assume you mean the condenser fan motor ? Try to manually spin it. If it is hard to turn, change the motor. If it spins freely, change the capacitor.

Fan or capacitor?


I would say the motor is bad but to be sure test the voltage to the motor with a multimeter, you can also phisically spin the motor and if that makes it work a little not as fast and blow enough air then you know its the motor this works if you dont have a multimeter.
