Jeff! Thanks a lot for the reply!

I took off the back panel at the bottom, and watched it. The relay
(white color) on the black compressor turned on, but nothing else
happened. After 10 secs it clicked off, with a small blue spark flash.

I tapped the compressor a few time, shook it a bit. Next time the relay
clicked, the compressor started up and did its thing! It didn't click
off after 10 secs either.

So, what's the next step. I'll leave it alone for now and see if it
cools ok and runs. If it stops again, what should I do? In the US, do
people normally have someone come out to repair it? If so, should I try
the relay first and do it myself? Any opinions welcome. I'm quite
handy, sometime at least!

Thanks

Dean
