Question about Heating & Cooling

The compressor fan does not spin and sometimes it spins backwards

Have a York less then 3 years old unit, the fan stopped spinning, and hummed. Took out the capasitor and cleaned the terminals - put it back in and the fan spun back wards - I suspect the capacitor is not functioning properly, and that the fan motor sustained damage.....I also inspected the fan motor unit, and the shaft spins freely......at this point I am ready to replace them both. Now the next question - I have found the motor and capasitor on several sites that support HVAC - what I found was capasitors for 18$ verses the 118$ i am being qouted at stores and most web sites....what's the difference?

Your capacitor is definitely the culprit here.
It should be a dual capacitor. Meaning it has 3 terminals on one capacitor. "C" "H" and "F" would be the markings for power in,"C" out to fan "F" and out to compressor "H".
It also has a mfd(microfarad) value on the capacitor as well as a VAC rating of 370 or 440 volts ac. A 440 VAC can be used in place of a 370vac.
The other specs may be something like 40/5 or 35/5 or 40/7.5 etc.
The capacitor replacement should be exact as far as the microfarad rating is concerned.( eg. 40+5).
The money requested through various sites is just that....various. These dual caps may sell around 30-50 dollars for a quality capacitor. If you wish to spend the $118 I will sell you all as many as you would like.

Air condition motor not going on


check to see if the fan is running if not it has frozen up over the winter. turn off fuses to a/c unit then try to turn fan by hand,if not soak down fan bearings with penetrating oil like PB Blaster keepmoving fan blade back and forth until it spins freely. Then try turning on the power to a/c unit if motor then turns fan freely , shut it down again and use a good coat of a-1 motor oil (ELECTRICAL) on the fan brgs. This should get you through for another year or so. On the other hand if fan will not spin by the motor now but spins by hand then the fan motor is bad.

My condenser fan is running backward


An abrupt cycle of power can cause a motor to run backwards. If you turn the power off again and wait 10 seconds or so (enough for blade to stop spinning) it should run the right way. Put the capacitor back the other way and try again.

Replace the capacitor inside the control panel on the outside unit. The top of the capacitor may be puffed up.
The fan motor may also be going bad. Change the capacitor first. It will have to be changed anyway if the motor is bad.

My air conditioner has stop working its blowing air inside but the fan is not spinning outside .....


If the fan is not running is the compressor not running also...if neither is running the possible reasons are 1..no power to outside unit...2..bad contactor on outside unit.is this buzzing if it is this indicates no power...3 bad capacitor,do both compressor and fan humm then quit humming and hum some more...4 high pressure switch has shut unit down because fan wasnt running if compressor was running but not fan....if your unit has this there will be a manual reset button where the lines come out of unit...if compressor was running and fan was not...1 bad fan...2 bad capacitor.. if you do not have any electrical knowhow i would recommend calling a hvac tech to come and fix unit...Thanks

Fan does not spin


Window unit or outside unit? Start and run caps are large problems,especially after several years operation or a lightning storm. Post more info. A humming sound in a fan or compressor that won't start usually means the capacitor got blown out.. It cost less than $30. (plus service call). LOL

REFRIGERATOR IS MAKING A BUZZING SOUND, not cooling


You have one of two problems going on. Your fan is spinning at hitting the sides. Or your compressor is shot which seems to be more the problem and even though it is cold the humming sound is a warning for you that the compressor is shot and it is more affordable to replace the fridge then the compressor. Sometimes compressor can cost more then the fridge.

Air Handler Blower Unit Humming


More then likely it's the transformer. It may be getting weak. I've seen them hum/vibrate almost new and last for years. It's more an annoyance than anything.
