Sorry maybe I didn't make clear what I was trying to say. By the way the opener I'm dealing with is a three quarter horse Sears made by Chamberlain and it's plenty has enough power to lift my 8 foot door. The opener isn't at fault, there's no way that two garage door openers blown exactly the same way. The converter on the logic board that converts from 110 to down to 24 volts is what keeps blowing. It has nothing to do with the garage door or the opener. I'm trying to figure out while using surge protectors how is it possible for transient voltage to come thru and keep trying the logic board. It is happened to both openers but it different times. the logic board that I just replaced about 6 weeks ago was a Chamberlain logic board straight from the factory and now it's blown too. Where is it possible that the voltage could be coming from and how is it possible that it's going through the surge protector frying the logic board but not frying the surge protector. That was my question not anything about the garage door size or the brand of opener
