Kenmore trio refrigerator not cooling

The Er Co error code signifies a communication error between the display control board on the freezer door and the main power board on the outer back panel of the refrigerator.

Check the wiring and connections between the low voltage interface and the main high voltage board.

If you are able to unplug the refrigerator and remove the cover over the control board on the back of the refrigerator,
you can check the wiring connection on the main control board.

If this wiring connection is okay, check the wire harness connection under the hinge cover on the top of the left hand refrigerator door.
If these connections are okay, then you will need access the wire harness connection in the dispenser.

No, it is not a failed condenser. You need to see if the compressor is running though. When it runs you shaould have a fan in the freezer running, a fan underneath the fridge running, and the compressor should be running. I would be willing to bet that either the compressor is bad, or the start relay on the compressor.

check the over-load/contactor on the side of the compressor,remove it and shake it if it rattles,replace it

There are a lot of things that could be the source of the problem... is there no cooling at all going on in the freezer? Is the back wall of the freezer cold? It could be anything from a fan, to the compressor, to the control board... you need a technician.

I would get on the phone with Sears, and explain the continuing problems you have been having, and they may agree to cover service.

This is the 1st (and easiest) step to take:

1. Turn power off to the refrigerator (i.e. unplug)
2. Leave OFF for at least two minutes to allow the CPU to reset
3. Turn power back on (plug in)

This solves 98% of these problems with the Kenmore Elites.

Step two would be to call service.
