Verify 24 volts at the low voltage transformer inside the air handler. If it is OK, jump out the red/green and yellow thermostat wires. If everything comes on, replace the thermostat.

Getting into window unit is tricky. The motors go out quite often. Might be capacitor. But you have weigh wether it cost more to fix than replace. Rus

SOURCE: 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.

SOURCE: Air Conditioner Compressor Fan Quit

Check the start capacitor. You may be able to see visual deformaty, otherwise, use a meter. The buzzing is most likely the contactors closing which uses a seperate 24v supply..

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.

Out of the blue, my Carrier 38tkb fan is not working; we hear a humming sound inside the outside unit; the unit is 7-yrs old and had no issues so far; any idea where we could find a service manual...


Hello, if the compressor is running then it is either a bad capacitor or bad fan motor, an easy way. To check is try to spin the fan blade with a thin object, if this gets the motor going the capacitor is bad if not the motor is shot.

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.

Should the an on my master 150000 btu be hard to spin . My wont run all of a sudden. It keeps tripping the reset button aftera humming sound for a few seconds


the fan should turn freely. those fans have a tendancy to dry out and will trip the reset. if the fan isn't shot completely, try oiling it and working the blades until they loosen up. most of the fans used on these units are not bearing type but brass collars which dry out. if they don't loosen up, the fan is probably too far gone. usually the humming indicates the motor trying to turn the rotor but can't turn the dry rotor shaft or a bent blade stuck on something. good luck jay

Motor outside is humming like it on but the fan isn't turning


Sounds like the run capacitor is bad or the bearings or siezing up. Turn the power off to the unit, then spin the fan blade to see if it spins freely, if it does then it's probably the capacitor.

Hampton bay fan noise


The fan does not need to be oiled. The bearings are what manufacturers described as "permanently-sealed", which means that they're designed such that they don't require oiling. The manufacturers recommend against oiling, and if you really wanted to do it, you'd have to be an expert, because there is some very complex disassembly to be done, which requires specialized tools.

HOWEVER...

The problem is not related to oil. A lack of oil does not produce a hum. If a fan's bearings are low on oil, the sound generated is a scraping or brushing sound. A hum, on the other hand, is an electrical sound. All fan motors hum to some degree -- the cheap made-in-China ones, like in your Hampton Bay fan, hum more than others. There are some steps you can take to reduce the hum:

* If you are using the fan with a solid-state control (i.e. a dimmer), that will cause the fan to hum. These controls are dangerous when used with fans, and a fire can result. You should have a qualified person remove the switch immediately and replace it with either a regular on/off switch OR a discrete-speed (i.e. 3-speed or 4-speed, rather than variable-dimmer) switch. Specially-designed ceiling fan switches such as this are available at your local Home Depot or Lowes. You could also use a remote-control system.

* If you have a remote control or other speed control system, make sure that the pull-chain speed control on the fan is set to the "high" position (highest speed possible) and left there.

* Make sure that all the screws are tight -- this includes screws which hold up the fan's mounting bracket, hold the blades onto the fan, and hold any applicable glass onto the light kit.

* Even if you don't have a speed control, the motor will still produce an electrical hum -- and the blades, which are physically attached to the motor, serve as mechanical amplifiers -- they take the tiny electrical hum and amplify it just like the big brass funnel speaker on an antique gramophone (record player) takes the tiny vibrations of the needle on the record and amplifies them to a comfortably audible level. High-end fans have a rubber flywheel attached to the motor between the blade holders and the motor unit -- and since rubber doesn't transmit vibrations well, this effectively deadens the sound. Your fan doesn't have one of these, but you can effectively replicate the noise-dampening effect by putting rubber washers between where the blade holders touch the bottom of the motor AND between where the screws which hold the blade holders onto the motor, meet the blade holders themselves. This will completely remove the path along which the sound vibrations can flow to the blades, and thus your hum will stop.

I hope this helps you! If you have any other questions, or need clarification, please ask!
