Maybe it just wanted to be tortured.

All the capacitors look fine and now it even works when cold

I wonder if the drier blew some conductive debris that was intermittently making contact...

Also, always suspect the power supplies - sometimes they can lead to these annoyances if they are on the edge of failure, especially since their capacitors are subjected to a lot of thermal stress.

Could be the debre, but not the power supply, the power supply in the system has been recapped few months ago wheen I built the system.
I also Have 2 Power supplies I use for testing, it behaved the same across all 3 of them
