I live in an area of big open hay fields and ranches. Lightning storms strike trees and the ground all around my property, yet the house has never been struck since new in '92.
Lately close strikes blow out the circuit board and/or the infrared door sensors of the Sears Garage door opener. Getting costly. So I added a small surge supressor, and last night a storm blew the logic board AND door sensors just two weeks after replacing both of them! GRRRRRR!!!!
Nothing else in the house is affected, and most electronics and PC stuff is on surge supressor power strips or UPS. Last night a close strike reset the Cisco ISDN modem and also my wireless router. But no damage to them.
So why is the door opener so susceptible to lighting strikes near by?
I am also going to get a special supressor that has connections right on it for the wires that go to the sensors. I'll see if that helps.
