I have a Maytag refrigerator. My dispenser stopped working. The fridge still makes ice though. I replaced the chute and dispenser board. Still not working. It works just fine in test mode, but doesn't work in normal mode.

What was wrong with the parts you replaced? Look at these manuals and you can troubleshoot it: https://dl.dropboxusercontent.com/u/8010163/Maytag%20Refrigerators.zip
You will need your ohm meter to test the various switches to find the one that is bad.
