Amana # P7642505WL s/n 8803048030. About 30 years old for European market. Comp runs and lower freezer is v.cold but top part and fridge side are warm. Fan behind panel accessed at back of lower compartment does not run regardless of position of timer. No voltage on feed wires. If anyone can attach part or all of a manual to assist me to fix this family friend, I'll be much obliged.
