My MBF2254HEW is not turning on, freezer and fridge, after it was turned off to clean it. The lights are on and I unplugged it and plugged back on. Then I tried to push the arrow up to set the temp, but it doesn't work. No noise, nothing.

Are the light still on after you unplug it? THen you are unplugging the wrong thing.

On refridgerators I have had... turning the thermostat off.. doesn't kill the power to the lights...

Maybe it was on defrost. Look at these: https://dl.dropbox.com/u/8010163/Maytag%20Refrigerators.zip
