I expect a microwave to last two years, no more. I buy cheap and replace.

I’ve put about $150 in parts in my 2004 refrigerator to keep it going and it’s taken a bit of patience/skill to replace the typical short lifespan parts when they go out.

I have a neighbor that got four years out of a $2,500 fridge. They gave up and just had it replaced with some drama from Home Depot.

Dishwashers will last me about ten years. Already replaced the dispenser (wax motor) assembly just out of warranty. Probably have a few more years on it.

Yup, it’s frustrating!
