I have a chest freezer that went on the blink. I ended up not keeping the stuff down low cold, even though there is frost and ice on the top. I un-plugged it, cleaned it out and left it totallly de-frost for days. I plugged it in and I can hear it running, light buzzing, it will frost up the top corner, but nothing down in the bottom. Anybody have any experience with these? Its about 5 years old. New Freezers are about $600. So I d like to explore if its possible to fix, before scrapping. I understand most appliances are throw aways with reverse enginneering, not to last. But I also hate to pitch it, since its aparently working somewhat to freeze up the top. Any ideaa?
