The food in the refrigerator is freezing. I have had several calls to the repair guy. He changed the control panel but that doesn't seem to help. Now the water dispenser will not work. Any ideas?

This fridge unit isnt well known to me but most follow suit in design. I would say having an electronic board normally refers that there is an auger motor controlling the fridge temperature. As the demand for temp. is needed the electronic sensor will instruct the new board to open and close the auger motor flap accordingly. Possibly the motor is stuck or faulty or the sensor faulty. My bet is to check the auger motor. Call him in again and ask him to check it with you. (Normally mechanical control works with a thermostat whereas an electronic control works with an auger.
