I have some Low Voltage kitchen ceiling lights, each with its own
transformer. Recently, one of them has run for about a minute and then
gone
out. I've checked for overheating which was my first guess, but it's not
that. I've also checked for loose connections but no luck there either.
Any suggestions?

I have similar problems with LV lights and transformers basically in the
Summer (when its hotter) one or two LC lights goes off after couple of
minutes.

One was a faulty transformer, replacing cured the problem.

Other was transformer was lying in the insulation in kitchen roof. Managed
to push insulation away and stand the transformer directly on the
plasterboard and works fines.
