Question about Goodman CKL36AR36 Air Conditioner
My unit makes a very loud squealing sound off and on. I believe that it possibly is the capacitor. Where is it, and is this something I can repair myself? I purchased this home with unit recently. This home was empty for years. I went to the Goodman website, and am unable to find the manual. Do you believe this could be the problem, and if not what? Thank in advance for your assistance.
This is NOT the capacitor! I would not go opening up the control panel unless you know what you are doing as the voltage in there will put you to sleep permenantly. It sounds like the fan motor is about to go out. The unit will have a safety cutout switch by the unit. Metal box with either pullout or throw switch. Disconect unit using this, open top cover by unscrewing the holddown screws. Motor will have serial #, voltage, hp rating, rotation direction all of which you need to order a new one. remove wires, labeling them as you do so. Loosen mounting bracket around motor. Fan can be removed by loosening the set screw on the motor shaft. Measure how far from motor the fan is and make note as it needs to be put back in the same position. Set fan to side and remove motor from housing bracket. Put new on back in reverse. My BEST advice? Hire a pro for this!

the motor could just be locked in place from sitting...take a stick or something and try to see if it spins be sure of rotation! you can also give it a little nudge while it is on and it will take off! if this happens then you have a bad start compacitor but no there are no fuses that only protect the motor!

Your on the right trackbut if the outside unit is running fine I have to say no :) . Disconnect the power from the unit and look for visible bulging in the Capacitor(will look like a frozen coke can) If no visible signs take your multimeter and check the micro farads fo the cap if 10% less than rating replace. Also look at the terminals conected to the compressor they may be melted . I would like to know the Capacitor ratings and what your measurments were.

I install them every day and I have not had one make a loud grumbling sound. Sounds like you might have a low voltage (Thermostat) wiring problem. The only thing different inside the indoors unit from heat and cool is the fan speed, electric heat when on. The fan might be loose or out of balance and it only shows up at low speeds. Either way, the noise is not normal.

Without being there to see it and have only your description in front of me, it sounds like the fan blade could be out of balance.......but it sounds more like a loose fan blade hub. Most Goodman units offer a minimum 5 year parts warranty. The Labor warranty is questionable, but the installing contractor or the Goodman Distributor should be able to give you that information. Of course this would cover manufacturer problems and not physical damage. As far as a history of this problem with Goodman..........I've seen it with every brand. If there is a problem getting it under warranty, you might be able to purchase the blade yourself. Before replacing the fan blade, I recommend disconnecting the motor wires from the contactor, tape off the ends and remember exactly where they were attached.....then start the unit to see if the noise is still evident, if so, it's probably your compressor. I recommend a certified repairman....not the one that quoted you $800.00. If you hear only the compressor start up and not the loud noise you are discribing, then try replacing the blade first.
I hope you find this information to be very helpful to you. :-)

Testimonial: "good advice"
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.

Hello Kathy McAlister - Typically, when the washer is making or produces a squealing sound is due to an overloaded load. I recommend running a cycle with less clothing. If issue continues, then consult with a professional to accurately pinpoint any potentially more serious issue like a faulty belt or a bearing/pulley suspension problem. The washer could possibly have broken something off in between the tub and outer portion of the unit.
