Jenn air built in jS48CSDBDA no power no lights no nothing

[Angalenamarcinkus]

Hello I have a Built-in jin air refrigerator all of the sudden there is no power whatsoever no control panel lights no interior lights no compressor know nothing I've been trying to get this figured out myself but I've had no luck there was a small computer board it's the smallest of the 3 that had a bad fuse on it so I re soldered a new fuse and when I put that control board in the fridge is soon as I plugged it in it popped the fuse again I'm bamboozled and please need some help desperately thank you in advance

You have a shorted circuit, do not replace that fuse until you find the short or you could possibly do more damage. Need to trace the circuit on that board to find the problem, could be board or what ever connects to that board.
