      Having laid some theoretical groundwork in the last webinar, we're going to focus on practical considerations in this one. That means quick n’ dirty techniques for diagnosing sealed system problem using strategically chosen and skillfully interpreted temperature measurements.  Review homework from the first session on 10-2-2017. Home refrigerator practical design and operating rules-of-thumb useful for troubleshooting Practical application exercises Troubleshooting scenario exercise Techniques for making system temperature measurements for determining superheat and subcooling Sealed system diagnosis homework assignment (to be reviewed in the next webinar in this series) If you attended the first webinar in this series, this is your payday! We’re going to apply that keen, penetrating insight you now possess into money- and time-saving shortcuts you can use to diagnose real-world refrigeration systems on service calls.

596.58392890 Kenmore refrigerator freezer too warm

Recommended Posts

I am starting my first refrigerator diagnostics adventure.  Yeah me...

I have a 23' Kenmore side-by-side refrigerator (model 596 58392 890 - about 10 years old).
Recently, the food in the freezer has shown softness.   Putting thermometers in the freezer shows it is not cold enough - the temperature is normally 18-20 F during normal operation, but at times (defrost cycle, I believe) it rises to 40 F.   Not good.   The refrigerator side stays constant around 38 F.   

I have adjusted the settings to the coldest I can, but no avail.  I removed the back cover from the freezer compartment to view the coils.  They mostly entirely clean, but there is heavy frost right at the top - where it appears the thermostat is install - the thermostat is encased in frost.  The fan does run most of the time (except when I find the freezer in the 40 F state - again, assuming this is defrost).   I have vacummed the coils underneath the unit to make sure they are clear and clean.

The frost is on the top, end of the coil - the part of the coil that has the thermostat from where the coil starts along the coil past the first and second bend.   The frost is just on the coil and isn't built up on the fins or between the fins.  I am not clear if this behavior (frost on a small part of the coils & the thermostat) indicates a simple, low cost repair (like replacing the thermostat) or is a sign that this unit likely has a sealed system issue and so needs to be retired.

Any suggestions?   I have pictures of the coils and thermostat, but I haven't quite determined how to upload them here.

Any help would be appreciated.

Thanks,

Tom

You can use drop box or similar to upload photos. And  sorry for the possible bad news in that your symptoms sound like a sealed system problem.

Thanks for the assessment, abaesemann.  I did find a way to get more dust out from under the unit (leaf blower ... the ill equipped handyman's compressor), but I believe you are right that this unit has seen its last days.  I will see how it does overnight and then likely start the shopping process.

I appreciate your help.
