Question

Hi, I just got a new Oster refrigerator and I connected it about 5 hours ago. It is cooling ok but the sides of the cabinet are really warm to the touch, even hot in some areas. Is this normal? Nothing in the manual addresses this. I do have it plugged into a surge protector with a 9 foot cord going to the wall outlet. The manual says not to use an extension cord but I didn't think that would include a surge protector type cord.

Thank You for any help on this,

Mike
