Had a King Keg Kegerator that was not working. did some testing and determined it was the power supply board. This board is the replacement board for that one also. Wired it up plugged it in and perfect.
The placement of components on this Komos controller board are positioned slightly different from the original, and so I had to modify the controller board cover in order for the connecting wire harnesses to trail out of the bottom side of the cover. I essentially had to cut out that bottom side of the cover. The controller board did, however, solve my issue of the King Kegerator not turning on when plugged in.
My Keg King stopped working and I used an online troubleshooting guide to prove that the circuit board was defective. This guide does not appear to be available here, but you'll easily find it if you do an internet search for "Keg King Series 4 Kegerator circuit board troubleshooting." Shipping to Washington State was exceptionally fast and the price of the new board is excellent. The replacement board is laid out a little differently than the original, but all-in-all, it's not too hard to make the swap. And the bottom line... My kegerator's back up and running!
After a typical de-icing at room temp my Series 4 Kegerator died when plugging it back in the next day. Fan would come on and off but compressor never fired up. LCD screen would come on and off. Using this replacement fixed the problem.
