On a similar note - do you have a surge protector for your computerized sewing machine? Our house got hit by lightning 3 years ago & all our electronics were ok because our tv's & computer were plugged into surge protector but not my computerized sewing machine. When I talked with the retailer I bought it from, the 1st thing he said was "How is your sewing machine?" I hadn't even thought about it. It was fine but since then I keep it plugged into a surge protector extension cord. Just a footnote, the lightning blew out a ceiling fan, a ventilation vent from the ceiling, travelled 3 floors down to the basement & blew out the entire phone system in the house. We got away very lucky as it easily could have started a fire. Never underestimate Mother Nature !!!
