Kenmore/Whirlpool SxS refrigerator section not cold after repair... help

5 posts in this topic

Model 106.50792000 (Sears Kenmore by Whirlpool, side-by-side) ,  mfr date: 2000.

BACKGROUND: Couple of days ago found the fridge warming up. After doing some research in the forums, I found one possible cause - Start Relay... sure enough that was exactly it (PTC discs crumbled inside). Bought and installed new start relay (Klixon 4SP1023), compressor kicked in...

... freezer got cold rather quickly (don't know if cold enough, ~ 20 deg F according to a simple bi-metal thermometer), but the refrigerator section temp has remained at ~ 60 deg. F for 8 hours now!! Cold air is blowing from the freezer thru the vent in the upper left corner in the fridge section, but the air flow seems week , same 20 deg F at the vent (I have nothing to compare it to).  The fan behind the metal screen in the freezer section is/was operating.  I also cleaned the condenser coils undeneath the unit.  Freezer setting was Med/5, and fridge seting was 6.  Of course, I checked the doors being closed, etc. Compressor fan is running. Both sections are almost empty.

Any diagnostic pointers? What symptoms should I expect in this situation? something I could measure? i.e. different components temperatures, voltages, etc.?

Thanks in advance,

Alex.

PS   I also noticed that water filter, p/n 46 9908, that has been siting around for a while, does not fit in its slot all the way --- any ideas here?

if your freezer temp does not pull down below 20 degrees,there is a problem. if you are certain the freezer fan is operating,remove the rear freezer cover and observe the evaporator coils as the compressor operates- it should show an even frosting pattern throughout the length of the coils,if it has a heavy buildup at the end of the coils,herein lies the story.  compressor start relays usually fail for some reason,and you may have found yours. freezer should operate between plus 5 deg and minus 5 deg,with a good,even frost pattern.

kdog - thanks! I did check temps this morning, and freezer was 5-10 F, and frig dropped down to 50F.   I did take the freezer's lining panel out -- it took me a few minutes -- and the attached pictures show the results: immediately after taking the cover off most of the coils melted the frosting; after closing the door, 5 minutes later, even frosting appeared on those coils -- only the thick top tube and couple of tubes at bottom were still covered with thick layer of frost.

... checked again in a few minutes… and defrost cycle apparently has just started, freezer fan turned off; unplugged power, plugged back in... fan re-started, the heater gradually cooled down, frosting process started up again…

Anything else I could check while the freezer cover is off??

I'm still lost :(

Sorry to say, but that's not looking good. The tube that comes in at the top then runs all the way to bottom on right side is where freon feeds into the system. So the coils have lots of frost at bottom but look worse as you move up, it should be a good even frost pattern over complete evaporator.

You should wait for some other opinions from others that are better at sealed system work then me, I don't get involved in sealed system work at all so I could be mistaken on this one.

i agree that the frost pattern is inconsistent,and the freezer should have no problem attaining minus 5 degrees,imo, you are experiencing compressor failure,which explains why the starting relay failed in the first place- nice pictures!!  since it is a kenmore badged whirlpool,contact sears and discuss your repair options with them.
