The fan may be stuck because of foreign material or the fan motor bearings are stuck. There would be two sources of the heat - the fan motor is hot because it is overloaded, and the compressor and condenser are overheating because the fan isn't running. I suspect the hum may be from the stuck fan motor, but it may be compressor sound you normally do not hear over the fan noise.

It is possible the fan motor is not getting power. A quick check for this is to remove power from the air conditioner, then cautiously feel the fan motor housing (you would have to remove the fan guard to do this). If it is cold, there is no power on the fan, but if it is hot, the motor is getting power but is unable to turn. You do not want to do this with power on - if you should somehow un-stick the fan with your hand in there, you could be seriously hurt.

You need to turn off unit. The condensor fan motor is not allowing the heat to excape. If you dont have any type of head pressure control you will burn up the compressor, Check the fan body and see if its hot and see if you can turn the blade. if its hot let it cool down overnight and try to start it in the morning. Sounds like you have a bad condensor fan motor, let me know if i can be of any more help.

SOURCE: outside unit will not come on

could be the slow blow fuses in the disconnect box. check them for conntinuity if you don`t get continuity replace the fuses. check for power @ the contactor. the contactor is where the wires from the diconnect box attach to the ac. check both sides make sure your getting 240v be careful not to touch the wires ofcourse. if your getting power change the capacitor. may need a hard start for the compressor as well.

SOURCE: Fan outside isn't running and

The fan outside keeps your compressor cool, the compressor, if left running without the fan running to cool it down can get damaged, the fan normally gets its power from a switch box located outside or near
it. or the motor on the fan could have just gone bad. the fan motor is not as expensive as the compressor to replace. its easy to replace. sometimes what goes out 1st on these motors is the capacitor,the capacitor stores enough voltage to give the motor that extra push to turn. many times its just the capacitor that goes out. when you purchase a motor make sure you also get the matching capacitor.if you can turn the fan and it starts running, its the capacitor, if it starts running and has any kind of bearing noise then you will have to replace the motor. good luck!

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!

My air conditioner has stop working its blowing air inside but the fan is not spinning outside .....


If the fan is not running is the compressor not running also...if neither is running the possible reasons are 1..no power to outside unit...2..bad contactor on outside unit.is this buzzing if it is this indicates no power...3 bad capacitor,do both compressor and fan humm then quit humming and hum some more...4 high pressure switch has shut unit down because fan wasnt running if compressor was running but not fan....if your unit has this there will be a manual reset button where the lines come out of unit...if compressor was running and fan was not...1 bad fan...2 bad capacitor.. if you do not have any electrical knowhow i would recommend calling a hvac tech to come and fix unit...Thanks

We have a 6 year old air conditioner Byrant 591B. The outside unit is not working it make a slight hum when the thermostat is set to cool, but the fan does not run. The furnace is working fine


You picked the wrong picture...lol. You have a split system and that humm you hear comes from the contactor. That means the thermostat is asking the compressor which is outside to come on. If you hear the humm but nothing is working, Check the breaker and then replace the fuses in your fuse box by the condensing unit, or the outside unit if the breakers are OK. It should have a disconnect between 3 to 10 feet of the unit depending on your codes and city requirements. No matter what, if you stand at your unit and look at the conduit, it will lead to your electrical disconnect. It could be a sub-breaker or fuses. It is usually fuses because a breaker could take up to 6 sin waves to respond as where a fuse could take only 2 sin waves. Replace both fuses. As time goes on, fuses become warn from constant load changes and heat and sooner a latter, they just wear out like any other component. Change the fuses and fire your unit back up. If it pops the new breakers, you have other issues and it's time to call an HVAC guys.

Is it normal for fan on outside unit to be on while on heat mode


Yes, it is normal with a heatpump, you run the outside unit in cooling and heating.
It is also normal when the outside unit goes into defrost for the outdoor fan to shut off during the defrost mode and to see steam coming out of the outside unit, while it's melting the frost or ice, then the fan will come back on.

My heat willnot come on all i here is humm in the unit under the house and nothing inthe outside unit it is a "Googman-ARUF02400A1"


Ok, If you don't have a heat pump, you should not be hearing anything from the outside unit. I assume you have electric heat. I feel strongly that you have a bad fan motor capacitor. This is what sends a jolt of power to start the fan motor. Good luck and have a great day.
