Kenmore Coldspot 22 Frostless refrigerator, freezer side-by-side. Model no. 106.9532810 serial no. sc4021466 Manufacture date: 9/93. I noticed the outside of my refrigerator, where the two doors come together is really hot to touch. If you open both the refrig. and the freezer and feel the sides of the partition between the refrig. and the freezer the walls are cool, but the part where both seals come together on the outside has slightly discolored the white paint from getting so hot. I noticed this about 3 days ago, so I made sure both refrigerator and freezer are clean inside and the coils underneath are also clean. The cooling temp. is normal and seems to be working well.
