Just a quick FYI on this model; it is an Electrolux-built unit out of Anderson, SC, built 26th week of 2010. Use Frigidaire service manual 5995345245
(Frigidaire Refrigerator Next Generation Top Mounts Service Manual) available via this website for basic service information. Being a Sears unit, tech manuals with the data sheets are only available for Sears techs, but there should be a service data sheet hidden in the unit, either behind the kickplate or under/beside the compressor. Unless they decided to take them out to save money. Argh!
There were a few problems not released to the field in service bulletins. Check defrost thermostat for separation due to moisture entering the case and freezing, thus separating and rendering the t-stat useless. Also check drain tube under evap for block/freeze up. I ran into a few where the drain pan was malformed or damaged during manufacture, causing water to run down behind it and under the pan and instead of draining out it pooled, froze and blocked the tube. Also ran into ones where the thin foam sheet behind the evap assy was not properly attached and it slid down under the metal drain trough and blocked the drain.
Hope that helps. Good luck!
