Question about Air Cool AC436-GB Fan

1 Answer

When I turn the fan on you can hear the motor hum but it will not spin on its own. If I start the fan blades by hand then it will maintain speed? Is there a starting capacitor in the motor or what else can it be?

Before getting into electrical issues, I would see that both ends of the motor shaft that drives the fan are clean and not impacting the movement of the motor. Clean as best you can and hit with some WD40. I would also check to see if the manifold/flywheel that holds the blades to the motor shaft has started to crumble. This may cause the issue you are having and is a bigger PIA to deal with.

Why don't fan blades rotate?


Sadly Hunter doesn't want people dismantling their stuff and replacing broken or burnt out pieces. They'd rather you buy a new one. If the motor has burned out which is possible a solution depending on how handy you are is simply hunt down a similar replacement and reconnect it.

Make sure the new motor has the exact same leads and connectors as the old one had as some Hunter fans have more than two leads. The model I have has four leads: a black, a white, a green and a red as my model has integrated lighting controls by passed by the motor.

I bought a simple blower motor with the same rating only two wires and with a bit of solder and wire I hooked up the motor and lights separately. The new motor is much faster than the older one so I had to add a tiny 1-way 500 watt dimmer switch to manually turn down the speed.

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.

Hello, I replaced a light fixture on my existing Emerson ceiling fan. The light worked right away but the blades didn't turn. I could hear power going to the motor so I went back into the switch cup and...


Signs of a bad capacitor in a ceiling fan include:

  • Fan runs slowly or not at all on all speeds
  • Fan will not start but will spin if started by hand
  • Certain speeds are slow or do not work
  • The motor hums and turns freely by hand but will not spin

    The capacitor is usually a black box inside the switch housing of the fan. If this box appears burnt or melted in any way, that is also the sign of a bad capacitor and it should be replaced.

    have a good day !!

    After oven turned on for normal baking it starts to hum rather than typical noise from exhaust fan.


    If you're not hearing the fan turn at its normal speed, it is possible that your fan motor has become stalled. AC motors will often hum or buzz when they can no longer turn but still have power applied to them. This could be due to bad bearings, or a blockage of some sort. It's probably not easy to get to, but if you can hand check the fan it should spin quite freely. Be sure to unplug the unit before messing with the insides, or shut of its circuit breaker if it's a built-in unit.

    Isolate power from the fan and see if you can spin the fan blade by hand. It should move easily. If it does not then it is recomended that you replace the fan. The time it would take to replace the bearings in the motor would not be worth your efforts.
    Most fans do not have a start capacitor for the reason being they are not under severe load.

    Motor hums but blades don't spin


    It should have something in motor block blocking the motor to turn.
    when it is OFF position ,you try to turn it by hand to see if it spins freely or not ? You may hear a sound of friction that blocks the motor. if this is the case try to find a local electrical expert to unblock the motor..
    Good luck.

    Ceiling fan will not spin, but I hear it


    It most likely has a faulty capacitor not allowing it to start. Remove the light kit or the cap where the light kit mounts, the speed and reversing switch will be in there along with a capacitor. You should be able to buy a replacement capacitor at most home improvement stores.
