Failed Honeywell CH valve motor replaced on 2 Oct. That motor failed about
14 days later and was replaced today, 23 Oct. I'm assuming that the first
replacement really was a brand-new motor, and not one that had already
failed from another customer and been accidently fitted in mistake for a
brand new one.

The valve itself was easy to turn, so it hadn't jammed and caused the motor
to draw more current because it couldn't turn.
