I have a Kenmore side-by-side refridgerator (model 50264992) that keeps
freezing up (or stays freezing). I think the temp in it is around 30
degrees and my milk keeps freezing solid and my fuits and vegetables
keep getting ruined.
The problem soon began after the hurricane season here in Florida. My
wife made both the freezer and fridge section colder, so that if we
lost power for a while, things would be colder and and would last for a
little longer.

Now, if I thurn the fridge and freezer both to warmer settings (fridge
to the warmest), the fridge justs keeps freezing food. I have even
unplugged it for an hour or so?

Any ideas? Is there any part on the back that I can thaw out with a
hairdryer or something?

Sears is coming out in several days and I have the two repair options
before they look at it:
A) $45 diagnosis charge + parts charge + labor charge (with 90day
warranty)
or
B) $219 for everything and a (12 month warranty on evertyhing)

However, if I can fix it myself before the appointment, I can save some
bucks which I need.

Thanks!
