There is no indication of a door interlock, (preventing starting with the enclosure open) on the schematic. - doesn't mean one couldn't...

Unpolarised electolytics are just made up from back to back polarised electrolytics in one can, one of them is always reversed biased so...

New one on me too. I've only seen bipolar electrolytics in low voltage applications, particularly audio gear.

Simple things first. Make sure the STOP button isn't sticking. Then, continuity of the coil, (Yes the one you highlight), then the...

Is there a dimmer in the circuit? Dimmer to lamp compatibility issues are a common nightmare. Are they mains led lamps, or are there...

I, too, recommend an oil filled radiator. They combine cheap, safe and effective, and if you buy one with timer and thermostat as...

Check how high they need to be.

What are you testing the battery with and how ? If you are using a common multimeter, testing with no load is meaningless. If it drops...

You could easily make one of those which worked perfectly and safely. There is plenty of space inside for the necessary protection and...

Please don't try this at home !

You did say it tripped a few minutes after switch on. If it goes immediately then it's more likely where the fault lies, but still not...

Unfortunately random time RCD trips can be hard to diagnose. The fault doesn't even have to be on the same circuit, because adjacent...

What a mess. Hopefully the supply is isolated elsewhere. If you aren't sure, keep well clear.

Condensation issue maybe?
