Lately I’ve noticed that that the freezer part of our refrigerator wasn’t keeping stuff completely frozen despite cranking down the temperature. What do I know about refrigerators? Turns out, I know enough about mechanical/chemical engineering to be able to understand a diagram of a heat exchanger. I took off the top panel of the refrigerator (a lot of the mechanical stuff is on the top of this unit), looked around, looked at the little diagram showing how it worked, and saw tons of dirt. I figured that before I called an appliance repair person, I’d take a look to see what I could do. I vacuumed out the grill to the condenser and as I did, I felt a blast of air coming from the other side of it.
I said to myself, “holy cow, it can’t be that easy.” Well, knock on wood, I looked in the freezer this morning and the ice pop that was mush last night is much more solid. So, I might just have fixed my refrigerator. I’ll keep my fingers crossed!
