modern electronics are better
Modern electronics as a generalization are more resistant to damage from heat, moisture and spikes etc. But of course there is cost cutting which leads to poor design which causes failures, likely far more often then fragility of the components.
I often run across electronics that survive FAR more then I ever thought they could. Our radio club used to have a 100w 144Mhz RF amplifier that was used on one of our repeaters. That amp would sometimes see 3 or more hours of continuous transmit time and it wasn't very efficient. Even with 3 fans on it there were about 5 times that it just quit working. The poor RF transistors would get so hot they would melt the solder and detach from the PC board! The fix was always to just solder the transistor tabs back to the board and it would work again. After the first time I switched to silver bearing solder, and it still did it although less frequently, that solder melts at almost 600 deg F. The transistors never failed.
As for the failures of this particular machine, I don't know enough of the story to be able to even hazard a guess at the failure mode(s). I will surmise that anytime I hear of the same part failing 3 times in succession, I have to bet there was a problem that was missed during service. The SQ electronics are as good or better then anything else on the market today. But it is sure appearing that the SQ customer service and the technicians available to Robert have been an enormous letdown. Speed Queen really needs to step up their game in this regard.
