The customer called us with several issues with his Sub Zero built-in refrigerator. The initial problem was Sub Zero 690 no ice and water. I showed up on my appointment and troubleshoot the unit.
There were several issues. Problem number one was the icemaker was not producing ice cubes. I manually force the water valve to give me water flow and it did. So the water valve is working fine. Also, I pressed the 2 switches for ice bucket in the freezer and check if the icemaker receives electrical power and he did. The only thing which was faulty was icemaker itself.
The second problem was always ON light and nonresponsive buttons on the water/ice dispenser. The light was On this means that dispenser gets electrical power. Also, I offered the ice/water dispenser replacement to the client.
Here are the step by step procedures I did during this repair:
First, I removed the panel which is covering the icemaker. I unscrewed 3 screws which hold the icemaker. I disconnected the wiring from old icemaker. After I installed a new icemaker assembly. I forced the new icemaker to run the test cycle. It passed the all tests successfully. I installed all the screws and panel back.
Second, this Sub Zero fridge has custom make wooden panels. I this case to replace the ice/water dispenser we have to remove panels first. First of all, I removed the magnetic molding line inserted in the door frame. Then I removed all the screws which are holding side frame and frame itself. After I removed the silver metal inserts with metal holders. Finally, I removed the big wooden panel from the fridge door.
Third, now I had access to the ice/water dispenser. First of all, I removed the gray plastic cover from the dispenser. Then I removed 4 screws which mounts dispenser to the door. Finally, I disconnected the power plug from the old dispenser and install the new part instead. I tested the new part and it was working fine.
Finally, then new dispenser was installed I installed all door components following the backward procedures described in the second step of this blog.
As a result, now we have a working ice maker and ice/water dispenser.
Another happy customer!
