I see these newer dryers and front-load washers have what I assume to
be some kind of IC control circuitry and from what I've seen my
suspicions about this being a likely point of failure appear to be
correct. LG warranties the motor for 10 years but the circuit board
only for 2. I'm betting it's expensive to replace too.

For as many years as this technology has been around, why can't the
control circuitry be made more bulletproof?

I had to replace the circuit board on my RV furnace. *The old one looked
like it was basically just underbuilt. *The circuit paths were very narrow
and all the components were the smallest values possible. *

Looking at the size of traces or components on an electronic circuit
board is just about meaningless. Almost all of these today are
digital, which work on signals of micro amps. The only areas
carrying any current of substance, typically are driving a relay,
solenoid, etc. or part of the power supply, if that happens to be on
the board. That area of the board does need to have the proper size
trace.




The replacement
board from a company that just makes circuit boards was much beefier plus
was a better design as far as function goes.

I don't get it because they could spend a few more bucks on the electronics
and make it more reliable and simply charge a few more bucks for the
appliance. *Instead they get a bad reputation.
