This is a top frig, bottom freezer model with digital read outs. The frig has been running too cold, freezing eggs for example. I DID also have a small ice build up in the freezer. The light switch had just a tad of ice on it so it wouldn't turn on the light, but so little that moving the switch by had removed the ice.

I removed the freezer back, and there was a bit of ice on the copper line right where it goes into the condenser. I melted it with a hair dryer.

I have verified the digital read out with a freezer thermometer. It basically matches the read out at 0 for freezer and 39 for frig.

I have replaced the dampener 2 times. Both times it was working correctly, but making a grinding noise. It still appears to be working correctly. And the unit does not seem to be running continuously. From reading other posts, it seems I may need to change the thermistor. My concern is with the digital read out showing the correct temp, could the thermistor be bad?

Also, do I change the freezer or the refrigerator thermistor?

Finally, can someone tell me how to access the self diagnostics? I haven't been able to find this info for my model. Or is there a link available to a factory manual?

THANK YOU AS ALWAYS. This board is AWESOME.

I would replace the fridg thermistor and see what happens. I usually use a laser thermometer to check the freezer output temperature. If temperature too low, it can cause problems.
