Frigidaire commercial upright run not getting cold
I have a Frigidaire comercial upright freezer mod#ffu21c4cwo it's runs but won't get cold thermostat seems to work can't get to coils sealed inside I guess I can't find a fan the compressor runs the second shelf down from top gets frost on it about 8" on back shelf rail only there is a thin metal line that connects there I think it's a defrost line also can't find a defrost timer behind or underneath anybody have any ideas what I should do next very frustrating.
