How to replace Electronic Control Board. After consulting with your expert we decided to replace the circuit board. The part was promptly delivered but because it is common to a number of different units it did not come with specific instructions. After reviewing the control parts diagrams we decided that all the parts leading to the circuit board were held in by clips. That was correct but we had a hard time getting all to release. We did so with a flat edge screwdriver. That took about a half hour because we were being extra careful not to break any. Once we got to the board it was easy to unplug it and install the new one. Putting the housing etc back together only took about 5 minutes. We then plugged the refrig back in and after a period of time the temp reset to the 38 degrees it is supposed to operate at and the water dispenser resumed operations. 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
