Thanks for that, Richard. I got an LED on the freezer's compressor --
I'll do the same for the fridge in the morning but it requires
disassembling some furniture. My feeling now is that over-heating is
the most likely candidate. The compressors have often been in hot
weather but it is much less humid here in California than our usual
digs. But, I'm not totally convinced. It will be interesting to see
if the controllers show an error state at some point.
