Kenmore 106.72153111 not cold enough
« on: September 15, 2016, 02:30:29 PM »
I've got a Kenmore 106.72153111 that won't get cold enough.  Reads about 15 in the freezer, 35 in the fridge.  Coils are clean, charge is good.  There is a frost line on the evaporator coils of about one inch.  Defrost sensor read open when I checked it at max cooling.  I've looked at an online parts manual, but don't see a thermistor.  What measures the temp in this fridge?

There is a frost line on the evaporator coils of about one inch.
Charge is not good if you only have 1 inch of frost on the evap.

charge is good. 

How do you know the charge is good? Go back to my statement above.
Did you tap the system and check pressure?
If so what was the low side pressure?
What was the standing pressure when you unplugged it?

A very simple cold control in the FF housing .

My son tapped the line and checked it with gauges.

I was in electronic repair most of my career as well as hobby-wise, but my son came through with the refrigeration knowledge.  He's new to it, but that seemed extremely simple so I have no reason to doubt it.

Wonderful, can you ask him what the pressure was while running and what was standing pressure (unplugged and watched for 20mins)
While he is at it have him check the amp draw on the compressor.
Can you post a photo of what the evap frost pattern currently looks like (hope its been plugged in and running)?

4 psi low, 60 high, standing

It's a replacement beer fridge, and I currently have sufficient space in the main fridge for my supply, so it is off.  We plan to fire it up this weekend and do some more testing.  Hoping to get some ideas here to speed the process.
