I have a 3 year old Frigidare that has seemed to stop cooling as much the last week. The icemaker stopped at first but I decided that's because the freezer temp is to high. The fridge part is bearly cold and all the things in the freezer are thawing out. It still sounds like it is running fine- it's only 3 years old and there is no dust collection on the coils etc.- I've moved the food around inside to see if circulation was a problem but no difference. Does it sound like a compressor or coolant problem? Don't compressors have a 5 year warranty?
