I have two Sears garage door openers that keep blowing the motherboard. They both did it the first time within the warranty. But the labor to have them replaced was going to be more than me buying the parts and replacing it myself. I talked to a professional door installer and he said that if I'm having problems I need to put in surge protectors on both garage door openers. I bought one surge protector just for garage doors from Sears and bought another one off eBay and installed at the same time I put in the new motherboards. The half horse model lasted just over 6 months before it blew the surge protector and the motherboard. It was on a secondary door but I don't use it much so I just unplugged it and left it alone. About a month later the three quarter horse opener on my main door blew it's motherboard while being plugged into the surge protector but did not blow the surge protector. So I called the company that made the surge protector and file the warranty claim because it was only 9 months old and they sent me a new motherboard. I installed new motherboard and plug the unit into the surge protector that still worked. Now 6 weeks later the motherboard is once again blown and the surge protector works just fine. what in the world is causing this and what can I do to quit spending $100 a shot on a new motherboard? The garage door openers are on their own separate circuit and the breaker for that serve it has never been blown. The only other thing in the garage plugged in using electricity is a freezer but it is on its own circuit. This just isn't making sense to me nothing else in the house or the garage seems to have an electrical problem but these two garage door openers.
