You must verify that there is high and low voltage going to the motor. If you have 220 high and depending on motor 3 to 27 volts low voltage then you have a bad motor. If not, you have to find where the voltage stops, likely low voltage if this is the case

I want to fix my split system ac.


You are referring to the air handler portion of AC. One of the fan blades is hitting something. Kill the power to all of ac and air handler and open up the air handler by removing the panel facing you exposing the fan. Manually turn the blade and look for the offender. Bend back into place, put back panel and tape up properly and turn all breakers back on.

Ir maybe just moving the fan motor itself slightly will do the trick. Whatever is easier and works will do.

Goodman air handler ARUF036-00A-1A does not blow air in heating or cooling mode only hums/buzzes, what could it be?


Looking at the wall thermostat, you will see the fan switch that has two settings: fan auto, fan on.
You will need to place the fan switch in the fan on position for testing purposes.
This will make the indoor fan run continuosly, and never cycle off.
In the fan auto position, the fan will turn off when the thermostat temperature setting has been satisfied.
Remove the air handler access panel.
Is the air handler fan operating?
If the fan isn't working see if you can listen closely if it is humming, or can touch the motor to see if it is hot.
If it is humming and has a bad capacitor, you can tell this without having an electrical tester by spinning the fan wheel by hand.
Be very careful... making sure your hand won't get cut by the fan wheel spinning when it starts up.
If the fan spins and picks up full speed, replace the defective fan capacitor.
It is the shiny silver metallic cylindrical object with electrical wires attached to it.
Make sure you write down where those wires attach and turn the power off before removal as they carry 240 volts to the fan motor.
If you find that the fan wheel doesn't turn freely when you try to spin it by hand, the bearings have seized and you will need to find another fan motor of the same size, shaft length , speed , and horsepower to replace the defective motor.
Keep in mind that a humming sound in the air handler COULD be from the transformer instead of the fan motor.
The transformer is a black cube shaped device with electrical wires attached to it.
If the 24 volt transformer goes bad, your thermostat will not function and nothing will come on.

Air conditioner fan is blowing but not air coming


If you mean that your OUTDOOR AIR CONDITIONER FAN MOTOR is blowing AND no air is coming out of the vents within your house, it clearly indicates to me that 1 of 2 things are wrong.

Either (1) your INDOOR AIR HANDLER is NOT running or (2) the INDOOR AIR HANDLER is running but your PLENUM has come apart.

If your INDOOR AIR HANDLER UNIT is NOT running, it could simply be the circuit breaker is OFF/TRIPPED and simply needs to be turned OFF; then turned ON. If that does not FIX your problem, then it is most likely your 5 micro-farad run capacitor for your indoor fan motor needs to be replaced. It will prevent your indoor fan motor from energizing. Worst case scenario would be your INDOOR FAN MOTOR has windings burnt and needs to be replaced. If your indoor air handling unit is equipped with a CONDENSATE VALVE CUT-OFF SWITCH, check to see if your drain pan is filled, thus energizing the switch. If the CONDENSATE VALVE CUT-OFF SWITCH is ENERGIZED, it will prevent the AIR HANDLER FROM energizing. That is the design and the reason for this valve.

Good luck.

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.

Lg ac shaking violently when turned on


Sounds like your fan motor is coming loose from the mounts or your squirrel cage is loose or loosening. That's just the air handler, the compressor is outdoors in the condensing unit. Pull that air handler apart and find out what's causing it, or shut it down. This can hurt you if the fan flies out of there.

My air handler fan will not come on during heating but will operate during cooling - Anerican Standard unit TWEO65E13FBO


Hi,
Please check the thermostta first. Take the thermostat to the air handler and hook up on a short thermostat leash. The unit should work properly, then its for sure that the problem is going to be in your thermostat wiring. If problem persists then we are troubleshooting a thermostat.

Let us know if you need further assistance.
Thanks for contacting Fixya.com

Air handler fan appears to cause thumping noise


If it's a belt drive check the belt or the pulley could be worn. If it's direct drive check to se if something is in the fan wheel causing it to be out of balance.

Lennox CB26UH Air Handler stopped running


Do you mean the air handler fan doesn't run but the outside part runs? If that is the problem, try turning the fan blade with a stick. If it turns freely, you have an electrical problem. It could be a relay, a bad motor winding, a bad capacitor, or a bad thermostat, among other things. If the fan won't turn, the motor needs to be replaced.
