Complaint was Freezer and Beer Section not cold. Tech (not me!) replaced mainboard with board # wr55x10942. Refrigerator operation was too his satisfaction. House was empty so no feedback from cust. Get a call back, freezer is cold, beer section is warm. Goes back out, says evap fan is running super slow. Orders evap fan. I go to install evap fan and discover damper is closed. Opened up the damper, cust calls back the next day saying fridge is warm still. Im thinking its either misalignment on the hinge leaving the light switch open and making the board shut the damper, or original fan has taken out new mb. Or both. All I need is better diagnostic info for this board so I get in there with a meter and test it out. Ive searched and searched for it, and I swear it was on this site, but I cant find it. Can any of you venerable masters help me out?
Thank you in advance.
