"The refrigerator is intermittent, and I didn't find anything out of the ordinary. The customer believes they may have closed the door too hard, and somehow, the door stays open, causing the unit to warm up."

Found that the left side door was high and hit making connection with the freezer door read switch. I adjusted door and replaced read switches. Now refrigerator recognizes that all doors are shut and no longer making door alarm noises. Refrigerator is working good.

Installed new drain hose and tested no leaks works perfectly.

"During the visit, the customer complained that the machine was loud and behaving strangely, not stopping, and going out of timing. The previous technician replaced the main control board, which made the situation worse. To resolve the issues, I replaced the User Interface (U/I) board and set up the unit as new. I also assisted the customer in setting up WiFi communication, and after testing all the cycles, the machine is now running smoothly and sounds nice."

"I cleaned up the main filter as the machine was not washing at all. I also noticed the water valve staying open, causing a slow fill in the wash housing. After cleaning the valve multiple times to remove contamination, I put everything back together, and it is now running with no issues. However, the customer insists that the 4C alarm will come back. Despite this, she is happy to see results after several visits from other technicians. To properly fix this unit, we will need a new water valve.Part # DC62-30314L - Valve.
