Is the compressor running? Check the circuit breaker or disconnect that is close to the outside unit if it isn't. It may be tripped on high pressure since the fan isn't running. If the unit has power, use a screw driver or something that will reach the fan blades and spin the fan to make sure it turns freely. If it doesn't the fan is probably bad. Next, check the capacitor for the fan motor. If it looks swollen then it is bad, otherwise check it with a multimeter. Most heating and air suppliers will test it for you. If the capacitor is good, the problem may be you fan motor.
You can check the fan windings with an ohmmeter.

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.

Ac unit isn't blowing


It sounds like your freezing up at the coil, which in turn, blocks airflow across coil and only a small amount of air comes out of the vents. This also explains the cold air coming from fan on the outside unit, since the system cannot absorb the heat from the inside of the house through the coil. Your air outside is usually blowing out warm to hot air because thats the heat it rejects out of your system. I would turn the thermostat to "OFF" and turn just the fan setting to "ON" instead of Auto, this thaws the system out faster. Give it time to fully thaw, make sure filters are clean, and check airflow. If airflow is back to normal, your problem is more than likely the charge of refrigerant. If you have to call a technician out, make sure the unit is not frozen at all before they get there, they would not be able to do anything with the system froze. Hope this helps and good luck!

A C blowin hot air. cecked unit outside. Fan is not blowing. Turned off, allowed to cool off. Unit worked 10 minutes. now blowing hot air again


Sounds like another problem with the capacitor being bad, if you cannot hear the compressor operating either this may be the case.

Goodman A/C won't cool


Fan motor or capacitor has gone out. Running the unit with the motor not running can cause damage to your compressor

The fan is not turning on my outside air unit but it is still blowing hot air through the vents. There is also ice build up at the bottom of the unit. It is making a humming sound.


You will need to replace the outside fan,or condenser fan motor.
Shut unit down,before the compressor gets damaged.

Without the condensor fan the heat will not be blown to the outside air and the unit will not cool.

You may be low on freon too,have it checked.

Check your outside unit to see if fan is running. If it is running check to see if air is blowing out if not you have a bad capacitor. Some times if a capacitor shorts out the fan will run backwards and the line will get very hot same as if the fan is not running. Russ

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)!
