My experience matches yours: computerised control of things like furnaces and dishwashers may have made them cost less to run, but it's also made them more costly to repair. Subjectively, it also feels as though it's made them more likely to need repair. Had the A/C evaporator dripped down into the works of a pre-computer furnace, perhaps some corroded contacts might have needed cleaning, or maybe a relay might have needed replacement -- that kind of thing. An easy, quick, on-the-spot repair. This is no longer possible; instead we get "Can't do a thing for it. Control board's dead. Hafta order a new one."
