1988 heater control panel gone crazy
 

Looking for ideas on a 88 digital heater control panel. Mine randomly displays crazy rolling numbers (seems to be a issue from my searches). Sometimes its fine, others not.
I have the dash all apart doing many other things & just remembered this issue, long as I'm in there right? lol. I see Batee has a repair kit that looks like all kinds of fun but the price is great-

Has anyone used this? I looked at rebuilder services, but they have to just be using the same parts as the Batee kit right? Hesitant to gammble on a used ebay unit, but maybe for the right $$??
Any indeas? Thanks!
