Outside fan not turning

I have inspected the outside unit, there is no debris but the fan barely turns. I can spin it by hand but it won't stay spinning. I have also verified it is getting power. Is there a reset button? If so, where is it?

    Yes, it is humming. Can you approximate the cost to repair? Is this a diy thing or one better left to a professional?

Either the fan motor's brushes are wearing out, or the relay is going bad. If there is power to the motor, than the motor is faulty.

Is it humming? If so you may have a bad capacitor and or fan motor.

    If you have average mechanical skills you can do it. Make sure you get an exact replacement motor and mark your wires so they go back in the same place. A motor probably around $75-$100. I would try a capacitor first though for $10 or so. If it doesn't fix it, you'll still have it for the new motor which a capacitor should be installed with the new motor anyway. Make sure power is off before starting. *Note the capacitor looks like a little tin can and should be mounted in the outside unit control panel. If it is swollen or oily you probably have found your problem. They can be bad though without these tell tale signs.

I have a Ruud Zepher Serris Central A/C & Heat unit - forced hot air. I cleaner the dirt and debris out of the outside unit put back together and now the outside unit will not start. There is power...


if you have power to the outside unit and the fan is not turning - the most likely problem is that the fan motor is bad. I would make sure the power is all OFF and then try and turn the fan blade by hand. If it's stuck and will not turn or turns 'hard' - the bearings have gone out and the only fix is to replace the motor.
If the fan blade turns freely - then you might check the capacitor (small electrical device attached by wires to the fan motor) and see if all the connections are tight and complete and that the capacitor itself is not bulged.
If it's 'bulged' that is a good indication that it's bad and that could be your only problem.
Otherwise I would either change the motor myself (if the bearings are out) or get an AC Tech to troubleshoot the system.
Hope this has helped.

What will stop the fan to stop spinning on a goodman ac unit on the outside


If you are wanting to just get it to cut off because it won't do it on it's own, you can turn the a/c breaker off at the breaker box. I have seen alot of blower fan switches go out on older goodman units and the blower stays running all of the time. Get a technician to check it for you. Good luck .

The central air turns on, but does not cool. The fan outside of the house is not moving. Is there a switch I need to use to turn the outside fan on?


There should be an electrical box next to your exterior unit. Open it up and there should be a pull handle on an electrical bridge. Usually when it is turned one way it will make an electrical connection and if it is rotated 180 degrees and plugged in it won't make an electrical connection.

You may need a new start capacitor or fan motor.I would have the capacitor checked by a electrician and changed if needed. Good luck and thank you.

Lennox central air for home not kicking on. Fan on the outside not spinning but motor is making a humming noise. No cold air coming in home. We have circuit breakers they are turn to the on position. ...


Is the indoor fan working? The problem with the outdoor fan sounds like it could be your capacitor. Turn off the power to the outdoor unit and make sure the fan turns freely using a screwdriver or something that will reach the blades. If it turns freely then it is probably the capacitor. Let me know what you find.

Daily reset of outside unit


I have the same unit and was having the same problem. My brother works on A/C's and told me that the coils most likely needed cleaning from the inside out because when they are clogged with a lot of debris the system will overheat and cause that switch to trip and so far it has worked. What you need to do is turn the main breaker off to the outside unit first then take the four screws out of the top of the unit, use a flat head screwdriver and lift the fan it's self up out of the carefully taking caution of the wires going to the fan, then take the garden hose with a spray nozzle and wash the coils from the inside spraying through the coil to the outside and then wash the louvers off of all the debris and this should help.

Goodman split unit that heats instead of cools


Hi, Could be a run capacitor on the fan motor. They usually swell up and or leak when they go bad. If not, the only real way to test them it with a specific capacitor tester. A new capacitor would be cheaper. Make sure that the outside unit is disconnected from power before opening it up, try to spin the fan blade by hand. If it doesn't spin freely it may need oiled if possible. See above solution. Your problem is the fan motor though so if this don't do it, It will have to be replaced. If this helps, Please rate my solution. Thanks, kstfas
