Upon inspection of the GE Monogram built-in refrigerator, it was determined that the ice maker was not producing ice. After a thorough examination, the ice maker was found to be the root cause of the issue. To resolve the problem, I replaced the faulty ice maker with a new one. The new ice maker was installed correctly, and the refrigerator was tested to ensure proper functionality. The ice maker is now producing ice as expected, and the customer is satisfied with the repair. This repair required technical knowledge and expertise to diagnose and fix the issue.
