If it fails intermittently it’s very likely caused by cracked solder joints or dried out capacitors in the power supply. I bet this GE control board could be fixed cheaply - if it was old, it might even not use a switching mode power supply, but an old classical transformer + rectifier - those are trivial to fix and no special parts are needed. The problem is though, there aren’t many electronic shops left which are able to do component level repair. Almost everybody replaces full modules, as it is much easier.
