Do-It-Yourself Stories from Customers like You No power to unit   Kurt F. • Greenville , DE • November 05, 2019

One of the three-door switches had failed. In my case, 00631512 or ref 25217585 on the left front of the unit. The green button no longer "clicked". When that switch fails, one of the ceramic fuses located under the top cover at the far back of the unit is blown. Used Volt-Ohm meter to determine which fuse.
