SOURCE: blowing hot air fan not turning outside making a humming noise

Replace the run capacitor. It is a silver cylindrical object located in the electical compartment of you outside unit. There is most likely three places on the top where different color wires are attached. One is marked F,or Fan. The center should be marked C, or Common, and the last should be marked Herm, with wiring to the compressor. Make sure you write down or label each wire you remove and it's correct location. They must be installed on the new part just like they were on the defective part. For you to know which dual run capacitor you need, the old one will have printed on the side either 370, or 440 v,as in volts. You must also need to know the microfarad rating and it is also printed on the side with the voltage rating. Since this is most likely a dual(runs fan and compressor) you should see two ratings abbreviated as mfd. Something like a 5mfd for the fan motor and perhaps a 35 mfd for the compressor. CAUTION !!! This device has line voltage and you must insure the power is off at the disconnect/ breaker BEFORE you begin the repair. Sounds complicated but really only takes a few minutes. The main thing is getting the right mfd and voltage ratings for the new part and keeping a record of where the wires were mounted on the old one, and putting them back the same place on the new part.

SOURCE: Tempstar smart comfort 2200 air

Hi,
There are quite a few things that could do that...
First... a bad t-stat or transformer.. is the indoor blower running???

Next, one of the limit switches has shut down the outdoor unit....that could be because of either high or low refrigerant pressure...

Fuse blown in the outdoor disconnect....

Low voltage wiring to the outdoor unit bad...

Contactor coil in the outdoor unit bad or contactor points bad....

Any of these things could cause what you are observing....to troubleshoot this you will need to be able to use an electrical meter properly and check power flow till you find the problem...

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.


The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

Tempstar Air Conditioner wont come on


Sounds like you need a new contactor in the condenser. The low voltage is grounded. Remove the low voltage (likely 2 wires) at the condenser and wire nut the wires leading inside. With an insulated screwdriver manually push in the contactor and be sure both compressor and fan run. Then replace fuse and turn power on to air handler with a call for cooling. Obviously the outdoor unit won't run because you unhooked the low voltage but if fuse doesn't trip then it's likely the contactor. Good Luck

Fan has a humming noise and locking up


a.if there were a dead bird inside, you'd know it from the smell! if the outside vent has the proper hood on it, it's doubtful a bird could get into it. possibly a roof-rat, but still- the smell!
b. have you 'de-greased' the filter lately? clogged filter can cause airflow problems, as well as allowing fan blades to become greased up and unbalanced, which could cause a noisy condition. if you can- remove the filter unit and check the fan blades for crud. use a gentle application of windex, rubbing alcohol, or some other gentle solvent to clean the blades. the leading edges usually pick up the most crud. you should be able to see this! carefully, using q-tips, or a small brush, clean off the crud! the fan's probably out of balance. WD40 works pretty well, too. also lubricates the shaft bushing that the blades are attached to. make sure the fan is turned off! duh!! good luck! also- soak the filter in hot water and a good de-greaser for a while, 'til you can see light through it. it's probably aluminum mesh- so use very hot water and a goodly amount of 'grease cutting' dish detergent. rinse well.
once again- good luck! the filter is probably held in place by clips. once removed, you will probably need a flashlight to work on the fan blades. put paper towels, or newspaper down to catch drips!

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.

Central ac blowing hot air outside fan not moving but making a noise


This is nothing but an either or -or ! First, make the thermostat calls for cool, there are suppose to be 2- noise outside, the fan motor and the compressor (and if a old system,a humming noise which is the contactor coil which picks up the main 240-volts).. hurry up and take a stick or something and turn the fan blades, if it picks up speed and run, then its the capicator. If not then the fan motor is bad.! (BOTTOM LINE)!
