The fan on the inside ac unit wont come on is there a reset button

One of the common problems in air conditioners is fan motor bearings going bad and the fan motor shaft is locked up stalling the motor or preventing rotation. Another cause of fan motors not running could be the motor start capacitor. The capacitor is needed to give the motor a jump start to get it rotating. If you can get access to the fan squirrel cage and can spin the fan ok, the motor bearings are then good. Most likely the problem then is a bad motor start capacitor that can be replaced. In very rare cases the motor winding itself could be bad and the fan motor will need replacement. regards, Dennis

Replacing a condenser fan in centralized A/C

On of the common problem with centralized A/C unit is a bad condenser fan. I have known people who called an ac technician to fix their ac because of a bad condenser fan and suggested replacing the whole unit! Costing them a lot of money when all it needed was a 50 dollars condenser fan! If the condenser fan do not run or it runs only when you give it a push, it'sbad. You will also notice that it is vey hot. When replacing a condenser fan you may want to replace the starting capacitor too. Replacing a condenser fan is not very hard, just make sure that the power to the ac unit is turned off at the breaker box. Confirm that the wires are not live by using a meter or an ac tester. The fan motor are held with brakets sometimes just screws. Most fan you can buy that has reversible rotation by just reversing the plug. Make sure it is blowing upwards. If not reverse the rotation. So if you notice that the unit is not putting out cold enough air and you went outside and noticed the compressor running but not the fan, turn off the AC right away and do not use it untill the fan is replaced. Running the unit with a defective fan can damage the compressor caused by overheating.

Outside unit fan does not kick on just hums and you can hear a clicking like a breaker kicking on and off.

thats a bad starting capacitor .. the capacitor is a metal rounded box about 3 inch x2 inch .. it has wires going into the fan and into the compressor .. its usually mounted near or on the compressor ... there are usually 2 capacitors in one container for the compressor and one for the fan .. if the capacitor is bad then the fan and/or the compressor will just buzz but wont start .. the motor will get hot until a thermal breaker shuts off the power .. then when it cools it will turn back on and try again ... if you allow this to continue it can damage things ... the capacitors don't cost much .. you can remove your old one safely as long as power is turned off at the circuit breakers for the AC ... note where the wires go .. usually they have "pull off" connectors that are different sizes so you cant mix them up .. take the old capacitor with you to an air conditioning parts house . or get your AC make and model number and contact the manufacturer for a replacement capacitor.. you can also take all the numbers off the capacitor and order a replacement off the internet .. replace the capacitor and it should fire right up ... if you call a service man .. tell him that you suspect the starting capacitor .. that way he will bring a selection with him or he might have them with him anyhow but if he knows your make and model number then he can bring an exact replacement .. ..

Home ac compressor fan won't turn all the time.

your looking at $175-$225 for just the single phase motor depending where you purchase, I just replaced mine(identical unit) due to screaming dry bearings, if you replace it your self make sure to keep new wires tight along side of unit or fan will cut them if loose and its a fan- 5mfd/25mfd compressor@440volt cap

AC roof unit stops cooling after rain

No, the units are sealed and the rain should not have affected the system at all. I would remove the outer cover of the unit and access the capacitors. Your start capacitor may be bad. You can visually inspect this and tell if there is a problem. Small black relay on top of capacitor often burns out, if so, replace capacitor and relay. If this looks fine, then we need to start at the thermostat and work our way forward.

Ac fan not turning on I can ''stick start it'' but which direction?

The condensor fan should be sucking air from the top and blowing it through the coils, probably a counter clockwise direction. The buzzing/humming sound is confusing to me. A humming sound sounds like a motor that can not turn over to start. A starting capacity would be needed. Just because you changed it out last year does not mean it is good. A buzzing sound sounds like a contactor problem. Contactors buzz and after a while, they will fail. In any case, you can "stick start" the condensor fan PROVIDED you are sure the ac compressor is working (this is for a short and temporary use). Also, you may have a high load duty capacitor that assists in the unit running. This will affect your condensor fan operation if it is not good. Unless you know all the components and operations of ac electrical, I would highly recommend calling out a professional.

Rooftop ac will not start

Sounds like your fan is not working but compressor is kicking in, am I correct, no fan working? If that's the case, I'd get someone qualified to check fan capacitor. The capacitor stores voltage at a higher rate 340-370 volts, to kick-start fan. Capacitors are relatively cheap and easy to change if your qualified and know proper procedure for handling them. Anyone not familiar with capacitors should not attempt it as they are very dangerous even when power is off.

Outside fan does not kick on just buzzes

The buzzing noise sounds like the contactor is energizing and if it is then you need to check to see if you have power 230 volts to the outdoor unit, if not, check the fuses or breaker, if you do have power then you may have a broken or burnt wire inside the outdoor unit.
