I have a Fridgidaire side by side
FRS6R4EB7 that is not getting cold.Here is what i have, Both fans are working,the compressor is working and sounds good,but the evaporator coil behind the freezer back wall only gets cold for the first 3 inches at the top with white ice crystals forming on those 3 inches and the rest of the coil staying at room temp.After a couple of hours I turn the machine off,let the crystals melt,try again
,but the same thing happens.I welcome any ideas,thanks
