Yes FF = freshfood , Er = error
Is the fresh food section at proper temperasture?
ok temp in freshfood ok ,
and freezer fan running ,
Does the freezer temperature feel ok ?
Since I've been opening it and closing it so much it is hard to tell. If I shut the power off to the frig, it will re-set the display and work for about 2 minutes.
ok that helps I`m assuming the issue is with the fresh food thermistor .
Mounted in the top of the freshfood section.
here is a link to the part .
