The refrigerator in my house was here when we bought the place. It's not top of the line (or even close). I could live with that but what has me worried is that I've noticed when it clicks "on" the lights flicker in the kitchen. Also, almost every time I touch it I get a painful shock to my fingers.
I find these things very alarming but my dh (who has done wiring and electrical work though not a pro) poo poos it as meaningless.
