in the last 3 years i bought a GE refrigerator, a Jenn Air oven and a
whirlpool dishwasher.

within 2 years, ALL of them blew out their control boards. anyone
have any idea what's up with all this? who the hell needs control
boards in refrigerators or dishwashers or ovens? this is ridiculous
and seems to be an effort by companies to create repair business.

I bet you had a big surge or a nearby lightning strike, or you
presently dont get clean power. I had lightning nearby blow out over
10,000$ worth of stuff, since then I installed a main panel lightning
arrestor and surge protector , individual surge protectors and
upgraded ground. Start by checking you have 120 or so then look into
protection. Is your area hit by lightning often.



*I would also check the grounding electrode system. Check the ground rod
connections. If it is an old house, install new ground rods. Check the
water pipe connection. Make sure the ground connections are tight in the
main panel.
