Hi,
In the past two years we had two episodes where my 2001 side-by-side
Kenmore fridge-freezer worked fine, but the fridge warmed up. Both
times were fixed by a hair dryer heating the cold air vent (blows
cold air into the fridge and what I think is a return vent (on the
lower side of the fridge) in the fridge. Can you tell me the most
common causes and what I can do to prevent another reoccurrence?

Thanks, Marc

Water is freezing and preventing air flow through part of the system;
blocking off the frig. I understand it can be three things. Something is
physically blocking some of the air flow (like insulation out of place). It
can also be a bad Freon charge, or it may be an air leak letting in too much
air and the moisture with it or (bonus suggestions) a defrost cycle timer
not working. I am sure there are a few other reasons as well.

Said to say I believe the Freon level problem is most common.
