A bad fan relay is not sending high voltage to the fan. A defective thermostat not sending low voltage to the fan relay.
How did you check the fan to say that it works?

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.

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.

Problem with Air Conditioner


there will be an access panel where the motor is located. 1st thing to check is fuse or circuit breaker feeding the air handler. this is on seperate power from compressor unit outside and usually has a fused or breakered disconnect on the side of the unit. if fuses are good or breaker is not tripped then switch fan mode to on. if blower runs in on but not in auto then it is a thermostat problem. if still no go then turn off power, remove access panel and find the squirrel cage fan blade. make sure it turns freely. it is very common for these motors to go bad. it can usually be removed easily and taken to a motor shop. I use Roy's Electric in Richmond, Va. They can test the motor on the bench and replace it if it is faulty.

Were is the reset button on the unit?


Hi, here is the theory on the reset button on Air Conditioners. They reset via the breaker panel box in your house. Check that first before anything else. However if your unit is popping breakers, it is because the rating for the breaker is incorrect, or there is something that needs servicing usually in the outside unit called the condenser. That piece contains the compressor. A faulty compressor and pop the breaker. Or If the condenser fan that blows over the coils of the outside unit stops (common failure) The compressor will overheat and shut down. That may not trip the breaker but the house will get hot anyway. Usual action for this is to replace the condenser fan motor and starting capacitor. Make sure the speed rating and directional rotation for the replacement motor is the same as the motor removed.
There are other reasons why the system won't come one fully. If the wall thermostat is digital and does nothing. including turning on the fan. There will be a small fuse located on the circuit board of the air handler (part of Air Conditioner mounted inside the house. It houses the circulation fan). That fuse could be blown. That one shuts down just about everything.
On air handlers mounted up into the attic crawl space there is an overflow pan. This pan is mounted directly below the air handler. This pan can fill with water when the drain pain contained inside the air handler starts to overflow because the drain system to that is clogged.
There is a "float switch" mounted in the overflow pan wired to the system in such as way as to shut down the entire AC system if that pan fills.
The handling is to clear the obstruction in the Drip Pan inside the air handler. Then remove enough water from the overflow pan and the AC will run as though nothing has happened.
If you have more questions, write to me on this site.
One thing more. The capacitor alone in the Outside condenser unit can fail and that will stop the condenser completely if it is of a "split" design and used for both the compressor and fan. When replacing this unit alone, ALWAYS find the same specification part.
I hope this helps,
Have a Happy New Year,
Mark

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

Whirlpool central ac stopped blowing air, cool or fan only. compressor outside running and attic unit on but no air. Solution??


If you are refering to the indoor fan that is not running, but that the outdoor condenser is operating, the next place to check is the circuit board in the air handler, this is the control for the fan motor. the relay may be bad that actuates the fan circuit. if the relay is bad there will be no power to the fan motor. If you have power to the fan motor then the motor is bad and the motor and capacitor should be replaced.

Home AC Air Handler is making Annoying clicking sounds randomly


It sounds like the problem is with the louvre swing motor which is either opening or closing the louvre but not stopping at the end. This is due to a faulty intergrated circiut (IC) programmable chip on the PC board. Only way to get around it is to replace the board.
