Had a failure a few weeks ago on a really hot day..
The 240VAC-to-12VDC power supply died after main power had been cycled.
I was able to replace it in about 20 minutes and got the unit back up.
The 12VDC supply is used to power my DIY 10A over-current shut-off circuit.

I took the case apart (two small screws) and found some swollen capacitors,
and a bad solder connection (It was open) on one of the AC plug lugs.
(made in China).
The flat cover of the case had cracks in it. Like maybe it didn't like warm inside the box and -2 deg F on the outside of the box.?.
Or maybe it was just the summer's heat?
