Mark K Binghamton , NY June 03, 2017 Control module stopped working (there were no error codes) I pulled the unit away from the counter, and unplugged it. I backed out 6 screws on the door. The door front came off and I pulled off the trim. I then had access to the control module. I pulled several pin connectors and then replaced the control Module with the new one. It was very easy and only took about 20 minutes. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
