Thank you for your post. In fact the damper IS fully open but no cold air is coming through it. I plan to take of the back of the freezer compartment to see if there is any ice build-up. This is an elimination process, and so far I see three possible causes :
- defrost timer faulty
- thermostat iced up and not working (but not sure if the refrigerator has a separate thermostat from the freezer)
- evap fan motor failure
I guess by the end of this process I will have a fairly good idea how Amana refrigerators work !!!
Best regards Gene and thanks again for the interest you show in this case.
