If you leave both controls to max, the freezer gets bitter cold, and the refrig side warms up. It's an odd thing, but that's what I've experienced. Sounds like the repair guy was ignorant. Some where in the middle of the range works best.
Glad it turned out to be a simple repair. Thanks for letting us know what you find.

An hour ago I unplugged the frig for 10-15 minutes.
More recently I set the temperature control to zero (off position) for the food section. I also set the freezer control to Normal. The repair guy had set it to max cold when he was here two months ago and told me that is where I should leave it.
I just checked the fresh food section temperature. Eureka! It seems to be cooling and moving my Wal-Mart temperature gauge back to the normal setting.
One of these steps must have definitely had an impact. I am left wondering if the evap coil iced over which Ed Pawlowski mentioned.
Or do you think it was something else based on the steps that apparently allowed the food section to start cooling again?
