To try to make it short: Fridge was not cooling, so cleaned evaperator coils (they were very dirty) as well as I could with the new "W"design of the coils. Still not cooling. There was ice in condenser coils visible so I blew hot air into condensor without taking cover off to melt ice and restarted. Still not cooling (only about 53 degrees f. in fridge). When I feel of compressor tubes while running small tube is hot, larger tube not cold. Should it be? If it is low on freon, is it cost effective to repair or best to replace? Fridge is not very old but this is this is the second problem I have had with this fridge. Air flow seems to be ok through fridge, no vents blocked.
