Power Tongue Jacks

Our Airstream is only a few years old and hardly vintage.  However, we 
live in it full-time, 365 days a year or nearly so.  We pull it about 
20,000 miles a year with kids on both coasts, so we may make our 
Airstreams vintage before the calendar might concur.

Question: Our tongue jack, a 3500 pound Super Jack made by H&H 
Engineering, a division of Barker, recently acted up.  It would go up, 
but not down.  So I finished unhitching and setting up manually.  When 
I put the head back on, the jack would go both up and down.  I then 
followed the instructions to put he unit in the correct positions to 
correctly  reinstall the head.  Then the hitch would go up, but not 
down.

At this point, I eMailed Barker and asked for troubleshooting help.   
They sent me a replacement micro-switch.  But before it arrived, I 
removed the the head and repeated the process of getting the head and 
the jack in the right position for re-installing the head.  At this 
point, the hitch now works properly.  It goes up and down. I have 
tested it a couple of times.  I am reluctant to go in and change the 
switch when the unit ain't acting broke.

Any suggestions?
