My freezer creeped up to about 15F over several days. I decreased the thermostat setting from 0 to -6 and the temperature went down to 9F and is holding. Then it went down to 0 and a day or so later was up to 10F again. Refrigerator appears ok. I have not done anything else but have seen several threads for similar issues but different models. Can you help me troubleshoot this model?
Thank you.
