It sounds like you fan motor has went bad. Turn off the power to the unit. Then remove the apx 5 screws on the outside edge holding the fan shield on top of the unit. When you lift up on this the fan will come out with it. You will need to cut the wires to the fan motor within 3 inches of the motor. Make sure to trace these wires they will be color coded but they fade where they are exsposed to the sun. Now take the screws loose in the center of the fan shield these hold the fan in place or it will have a clamp that holds the motor with a single nut. Most of the time the hardest part is removing the fan blade. Soak the nut and shaft with PB blaster, WD 40 or some other good penitrating oil. Let the oil do its job and then try to unscrew the screws holding the fan to the fan shaft. These screws will either be allen wrench type or an exsposed square drive nut. If there is rust on the shaft sand it off before trying to remove the fan. Once the fan is off (make sure you lable the fan so you know how it goes back on you dont want to put it on upside down) you can take it to a local electric motor repair shop and they will match it up for you or order one on line ect... They can use the mdl numbers on the fan to replace it. Remember to unhook the electricity before starting and when you put the fan back in use electric wire **** connectors you can get a kit from any hardware store or use twist caps and always tape the wires where you put them back together. You will have extra wire you can trim it or just tape it or zip tie it so it doesn't get caught in the fan. Your new motor will have a wiring diagram on it. Write it down because once mounted you will not be able to see it. The only difference may be that your new motor may have two brown wires that go to your capacitor. On your old motor you may have had only one. If this is the case unplug the old wires from the capacitor and remove them one of them will go to your old motor and the other to power. On your new motor the power goes to the motor and it supplies power to the capacitor its self. I hope this helps

My air handler fan does not come on, the outside unit turns on fine. Is their a way to reset the fan?


Check for fan operation by turning the fan control at the thermostat to "on". If the fan blows, it works. If not, check a circuit breaker or fuse.

If the fan blows when forcing it on with the thermostat but not in automatic, check the fan control circuit in the air handler. Danger: high voltage, beware! There should be a system wiring diagram inside the air handler somewhere.

Air handler working fine air conditioning unit outside-fan not working only get a buzzing sound




Hi,

The compressor is either locked up or the start capacitor is bad...

The buzzing sound is probably the compressor trying to start and cannot get started...

Hi, After finding out that Freon is low by seeing snow/icy surface on outside compressor, I went up in the attic to find snowy/Icy surface all over the coil inside the air handler. I wahsed it and made...


Hello
Your still froze up.There is a freeze cutoff device in the air handler upstairs.
Look for a thin silver color tube near the coil and follow it to the control box,there may be a reset button.If not, try using a hair dryer to warm up the coil and it should reset itsself.
These freeze devices can take an hour to reset on there own sometimes,do not run the compressor while doing this.

Ac sytem blows strong air but its warm


If the compressor and fan work in the outside unit, and the fan inside (air handler) works, probably the system is low in refrigerant which means there's a leak that has to be fixed and then recharge the unit.

Ac fan on, blowing air, but not cold


Check outside unit if unit and compressor are running feel the large line to see if it is cold. If compressor is running and line is not cold possible charge problems. You may have a capacitor problem outside. they go out quite often. You can change this yourself, Open up outside unit and the cap is the silver bullet with terminals out the top. Bad cap can cause compressor to not operate and also the fan. You need to clean the coil inside or at leat check the coil to see if it is clean. You can clean theis with a toilet brush do not go against the coil bit brush with the fins. You may need to call a service tech but try these options first. russ

I have a Goodman A/C unit. When I turn on the therostat the outside fan does not turn though there is a mild buzz sound. The blower blows warm air inside of my house. What could the problem be?


Does the cpompressor come on if not the sound you here maybe the contactor. Check float switch inside. It is underneath the unit or in front of the air handler. Drain stopped up need to blow out drain. Check outside breakers. possible bad capacitor on unit. Need service tech. Rusty

Fan not blowing


Even when the power is off at the unit outside the thermostat will supply power to the contactor of the outside unit. This may give a hum or buzz as you stated. If when the power is on to the outside unit the fan tries to start but only hums the motor may be bad. Does the compressor start and run?
