Yes this absolutely frosts my backside. Had a newish high end side by side fridge that mi esposa had to have. I don't deny the cook much on that front. The ice dispenser stopped working and I diagnosed the most likely problem with the Googles and discussions with the company tech support. Simple circuit board replacement on the rear of the unit. Ordered the part, replaced it and nothing.
It turns out the there are internal fusible links that are buried inside the blown foam insulation that you cannot get to with a blow torch and jackhammer. So now I have a beer fridge that doesn't have ice dispenser. I was not amused.
