i had similar problem with fridgidaire.

turned out the auto-defrost relay (?) wasn't functioning. this caused ice
to form and wouldn't allow cold air to reach the refridgerator part-freezer
worked ok.

not sure if it was a relay-it was some kind of timer that allowed heaters to
cut on and melt ice for defrosting.

hope this helps.

Was working fine then seemed to stop cooling. Pull out and cleaned all
the lint etc. from coils and it seemed to get better but its not back to
full function. Won't make ice but if I put ice in the bin its cold
enough not to melt. On the food side it is just cool enough to keep
things from spoiling (so far).

Any tips much appreciated.
