Product review (5 stars): Easy, money-saving DIY repair
This is an easy, money-saving DIY repair. You can find videos online explaining what to do. Please unplug your refrigerator or turn off the circuit breaker!

If you know how to work around line voltage safely and know how to read circuits too, you can find circuit diagrams to troubleshoot the old unit... and also test the newly installed unit without waiting for the first ice to freeze. For this purpose convenient probe receptacles are provided on the outward-facing surface.
