Have 2 FAH125 thru-the-wall units. Both 3 yrs old. Fans run on both but compressors will not kick on. No clicking noise or noticeable attmpt by compressor to kick on. Power to both is 220. Tested the outlet - is OK. Is this a cleaning probelem or compressor failure

My name is Peter. I am a retired field service refrigeration technician.
A clicking noise can come from several different areas of your unit:
1.) Your freezer cooling coil fan striking ice.
2.) Your bottom condenser fan striking a bent frame.
3.) Your Ice Maker.
4.) Your overload relay, which is mounted on your compressor and acts like a started for your compressor.
Are your fans running?
Are you cooling - freezer - fresh food section?
Send me the model number. The model number is on a label on the side wall near the top in your fresh food section.
The clicking could be the start relay.If the start relay is bad, the compressor will not start and you will hear a clicking noise in 2-5 minute intervals. The clicking noise is the overload cutting the compressor off when it overheats from trying to start with a bad start relay. To find out if this is bad first unplug the refrigerator. Remove the lower cover from your refrigerator. Then take the cover off that is on the side of the compressor,you will see wires going to this. Now you should be able to see the start relay plugged on to the side of the compressor and unplug it. Now the best way to tell if it's bad is to shake it. If it rattles, it's bad and needs to be replaced. If not, most of the time it's ok. But rather than saying the compressors bad, you might want to replace it anyways because it does not cost much. A quick check on the compressor is to remove the start relay. You will see 3 pins connect a multi meter set for continuity. You should have continuity between any of the 3 pins. If you do not the compressor is bad.Also check from each pin to a good ground on the cabinet. There should be no continuity if there is the compressor is bad. If you replace it and it doesn't work then the compressor is bad and you'll need to call a repairman. (Note that compressors are very costly and are normally not worth fixing).You can enter your model # at http://appliancehelponline.com/referclicking.html for diagrams and illustrations or to purchase a start relay. A 3 in 1 start relay will also work fine. All parts come with installation instructions. Not all models are available.
Is there is frosty ice on the freezer back wall, if so. Based on your symtoms I would suspect page 1, Item #4 Adaptive defrost control #4388931 Est $85 -120, Other issues, page 2, compressor start device, #22 start device #2225929 Est $45 - 65
the regulator/switches are either rusty, clogged, or need to be replaced. if you have some machanical aptitude and common sense this should be easy, if not have a pro or someone some knowledge of this type of thing handle it for you. in the future drain your compressor DAILY to avoid this problem
First of all, clean your outside coils so that you are assured of good cooling air. The compressors have an overtemp device that is usually internal to protect them against heat. If you have an air compressor use it to blow out the coils good. If the compressor will start, the capacitor is good so it sounds like a cooling problem with the compressor
from your description it sounds as if the compressor is not starting up. the buzzing noise usually occurs approx. ever 3-5 minutes and is followed by a click. this indicates either a bad start relay or a stuck compressor. and from the model you listed it is most likely the compressor. if the unit is under 5 yrs old it should still be in warranty thru sears.
Thanks for using FixYa Peyton
It will rattle slightly, this is normal. The ones that are burned out will sound like they have gravel in them, you can defininely tell something is wrong.
The problem with diagnosing Kenmore fridges with this problem is that there are different manufacturers. Yours is built by Frigidaire and probably has a Tecumseh compressor. We find more failed compressors with the Tecumsehs than we do with the models that have Embraco compressors. The models with Embraco's generally have more relay failures.
You should not hear the buzz/hum at startup. You will need to replace the compressor, which will be replaced at no charge to you if it is less than 5 yrs old.
If it is older than 5 yrs, you can have it replaced, but it will be almost as expensive as a new fridge. You can buy an aftermarket start device called a 3-in-1. This has a start capacitor built in to give it a little more boost on start up. I don't recommend using them unless it is a short term fix until the compressor can be replaced or if it is out of warranty and there is nothing to lose anyway.
