Hi,
I have a 3 year old Amanna frig with the freezer on the bottom. The freezer works but the frig warms up. I noticed frost on the coils in the frezzer so I defrosted the frig. It worked fine for about 10 days and then frost built up in the freezer again, then the frig warmed up again. From what I've been ready it sounds like it's the defrost timer, defrost heater, or defrost thermostat.Does any one know if it could be any thing else?also, where could I get a schematic showing me where the parts are on this Amanna Frig model number ABB2227DES, and wheres a good place to buy parts any help would be greatly appreciated.
