Input:
I purchased this suppressor because our refrigerator has required a new defrost control card twice in 6 years.  Each time the service technician comes out and finds the defrost control card has expired.  This is normal for this refrigerator, ( a Maytag double door (side by side), according to 2 different service technications.  We haven't had the surge suppressor long enough to determine if this will solve the problem.

I've had electrical surges causing occasional computer failures at work and a surge suppresser  always solved the problem.  All computers were always connected to the power lines thru a suppresser after that.  This item was the brand we used and it never failed to protect the computers.
