There are high end brands who have a guarantee of more than 10 years, but they're expensive and the cost per year comes about the same as the cheap ones.
One particular case was the refrigerator. No matter how much we cleaned it it smelled like mildew. As it turned out not only were the door seals bad, the internal liner was breaking down and the foam insulation had degraded. Replacing it with an A+++ rated model was the best thing to happen to us. Not only was it quieter, it only runs 1-2x per day, has more internal storage, and it cut the electric bill by 20%. This thing will pay for itself in 2 years with the electric bill savings only.
There are many things to be said about making old devices work again but sometimes you have to ask if it's really worth it. I'm pretty certain that old refrigerator pump would have ran for another 20 years.
