Hi Joe,

I have just finished repairing two rotators which exhibited
the same
symptoms and ... yes ... it was the pot in both cases ....
BUT!
It turned out to be dirt inside the pot. The wire-wound
element was quite
OK in both cases and they worked fine after a thorough clean
out with
contact spray. The units were both about 6-7 years old and
had been in
active service all that time. Don't know how the dirt got in
there. It looked
like tiny grains of beach sand adhering to the wire
elements.

Simple repair but unfortunately you have to dismantle the
rotator to do it.
