Hi all, new to site. My 15 year old RCA fridge freezer is working intermittently. The fridge is fine, freezer keeps defrosting food every other day or so. It's fine for a day or so, then nothing fit a few hours. The fan send to work fine, the cold are cleaned, the compressor runs fine, I have the dating between 7 and 8, but this sometimes freezes the stuff in the fridge too. Thanks in advance. PS this has happened already about 10 years ago but the repairman fixed it and I'm not sure what it was. Thanks Joe
