Thanks for the replies.
Gene: The fridge does not cool and there is frost build-up on the back panel inside the freezer. The fan has been running non-stop. Good thing I live in Canada and we have been having extreme cold conditions so I have been using my garage as a makeshift fridge!!LOL!! Sears tells me they can send a repair guy next Tuesday.....
Richappy: Thanks for the advice, I have NO experience in this area so would look for someone who does. Are the parts you mentioned made by Whirlpool? Could I request that they be installed vs the original model?
Thanks again for your help!
