Product review (5 stars): Relatively easy repair saves $$$
I had a GE electronic refrigerator with motherboard in the back of the unit that wasn't cooling the refrigerator section sufficiently.  The freezer section was still keeping items frozen.  Freezer was on top on this unit. I used the following troubleshooting guide to diagnose the evaporator fan motor as the problem then ordered the replacement from Amazon.  The fan replacement is relatively easy and prolongs the life of this expensive refrigerator without the cost of an appliance repairman visit.  I had replaced the motherboard  within the last couple of years so I was glad to see that it was just the fan this time around.  You Tube has lots of videos that show you how to replace the fan on most refrigerator types.
