No air coming out of vents is a sign that you may have a bad capacitor.
Attic ac unit not turning on.
Most homeowners are comfortable calling in an ac professional to troubleshoot the issue once they have a good idea of what might be going on.
If after changing the batteries the screen is.
Turn this breaker all the way off.
If it starts spinning then the issue is the capacitor.
Wait a few seconds.
If you suspect a problem check the following.
If the attic fan isn t turning on it could be an electrical issue a problem with the thermostat or the motor of the fan that s not working.
My ac unit won t turn on check your circuit breakers locate the air conditioner circuit breaker marked on your home s main power distribution panel the big circuit breaker.
In other words your air conditioner is not working.
The reason is simple.
There is a safety switch in the drain pan that when water fills the drain pan the switch prevents all or some of the air conditioning system turning on.
A bad capacitor can t properly power your ac s fan meaning the fan can t spin.
This is a quick and simple repair for a professional.
Your attic fan may not be turning on because of an electrical problem like a tripped circuit breaker a blown fuse or a bad connection.
If it s blank someone may have turned it off.
The capacitor may also be used to keep the fan motor running properly as well as starting it.
Now turn the breaker on again.
Look for problems with your condensate drain line when your air conditioner works it creates condensation which is drained out of your home via a drain line.
If you find that the ac unit still does not work the next probable cause is the thermostat.
You have a blown fuse.
Check the screen on the thermostat.
If you are unable to turn your thermostat on check and replace the batteries.
To find out whether your fuses are working properly you ll need a multimeter to do a continuity test.
This in turn stops the ac system from evaporating the moisture from the air so that no more water is produced.
If you leave the unit running the fan motor will keep attempting and failing to start.
Check to see if you need to reset a breaker.
The ac unit won t turn on usually when the outdoor unit doesn t turn on it is because the circuit breaker has been tripped.
Setting it to off turns off the blower causing the inside unit to freeze which makes your entire ac system shut down.
Regardless of the reason if the breaker that provides power to your ac unit trips the air conditioner won t turn on.
To test it use a screwdriver or branch to poke through the condenser unit s vents.
If you have a bad capacitor it may take a while for the fan blades to start spinning once you turn on the unit.
Gently push on one of the fan blades.
Simply turn it back on and you should.
When this happens you can easily reset it after locating the circuit breaker panel.
So make sure this power switch is in the on position.
