Question about Heating & Cooling

1 Answer

My central air also makes squeaky noise

My centrail air has the same problem. I was able to locate the blower but told if the unit has a capacitor, contact a professional. Mine has a small capacitor attached to the front of the unit. I wonder turning off electric power at the circuit breaker still isn't safe to oil? Could anyone provide some safety tips before I attempt to oil the blower? Thanks

All new blowers are sealed units you really can not oil them. By the time they start howling it is to late. Now some evap motros inside have two small plastic plugs on the motor. The outside one is easy to oil the inside one is blocked by the fan. Very hard to get to without pulling the fan. My suggestion calla service tech and ask for free estimate on motor service or replacement.Russ

Central air unit (the outside unit) works fine then fan stops and makes a buzzing or no noise at all, later works fine again then again fan stops


I would start by testing or replacing the blower motor resistor, it's located next to fan, fan wires goto it. When fan stops try tapping on it. The resistor is more common than the fan

Need to change a broken blower motor in RUUD central air unit. Old central air blower motor (GE electric) was connected with brown and orange wire to 15 MHD capacitor. Another orange wire from central air...


on the motor should be a diagram detailing the wires. brown white goes to either side of the capacitor and brown wire to other side of capacitor. hi speed goes to normally open contact on the indoor fan relay and the wire designated common on the motor goes to the other side of power from the relay contacts.

Very loud "squealing" noise from fan blower for


Hello, if you cannot turn the fan by hand then the motor is shot. However, when power is applied to the motor and it starts after you give it a push then its the capacitor. Whenever you replace a motor tje capacitor must be replaced aswell because the microfarad rating of tne capacitor may have changed.

I have emerson quiet kool but the fan with not turn it keep on making a miiiiiiiiii sound


Hi, what has happened here is you have lost the blower motor to the unit. Anytime a motor will not turn and makes noise as it is trying to start, the windings are about gone, and /or the bearings are froze up. I know this is a Emerson, but I don't know the model of this unit, or if it is a window/wall unit or larger. If it is a wall type unit, it will have a dual shaft motor in it for the blower and condenser fan. It would not be worth the cost to have this motor replaced unless it is a Emerson central heating and air system. It is possible that this unit has a run capacitor on it that may have failed, but when this happens the motor will just stop and not make any noise at all. The motor needs to be changed out if its a central unit, and if you want to get an estimate to change it out if its a window or wall unit you can, but it may cost you more then the unit is worth, just to be honest from my years in this business. Please keep me posted on this and what you decide to do. Please don't forget to rate this post as I know you will be kind. I wish I had better news for you, but this happens and there is not much you can do your self. I wish you the best.

Turned on a/c unit no air blowing from vents. unit is on out side runing


2 things could be the problem 1 The blower motor capacitor has one out. This is a small oval or round piece that the wiring to the blower motor is attached if this is out the blower motor will not work. 2nd. the blower motor itself has burnt out. Replace the capacitor and the motor together should you have to change out the motor. Good luck hope this helps

Central air does not kick in.


It sounds like you have a bad capacitor to the compressor. The humming noise is the compressor not starting up but is trying. It is either the capacitor or the compressor form your description. If you had a lightning storm or power surge about the time this happened it is most likely a bad capacitor. You can have the capacitor tested to see. Disconnect power before working on unit!

I have a Carrier 38ckc036350 Air conditioner. The inside blower turns on but the outside unit only makes a buzzing noise. I belive it is the capacitor, but I don't know where it is located any ideas?


Have you checked your circuit breaker? Capacitors are located in side the unit in the control box. TURN OFF THE POWER. you need a capacitor checker i assume you have one if not have a qualified service person check it out you'll be money ahead in most cases. good luck Tom

Our central air conditioning unit is out. The outside unit makes a straining noise but the fan does not turn. I can manually turn the fan blades.


Sounds like a start run capacitor. The motor may be bad too. The capacitor will look bloated if it is bad. There may be other reasons for these parts to fail. So please call a licensed technician for professional help.
