Would anyone be kind enough to tell me where (if anywhere) the high
pressure switch is located on a Trane XE1000 heat pump unit? My hvac
guy showed me a couple of years back but I have since then forgotten.
Plus I have two very different heat pump units which complicates my
memory even further.

Funny thing happened... I turned off all power to my heat pump and
tried to find the high pressure switch with no success. But now the
unit is operating as it should! I wonder if just shutting it totally
off for a few minutes reset the switch. (The problem was the auxiliary
heat did not come on, though the indicator light did.)

Hint:
You havent fixed anything. It "locked-out" for a reason. It WILL do it
again. NO, I cant and wont diagnose it over the internet. There are
only about 100 things it could be. Now is the time to get someone
scheduled in to do the repair before it quits for good.

According to Trane, my heat pump's high pressure switch will trip
during power surges. We've had a few during the past few weeks. So it
seems that was what caused the problem. This is based on it not
recurring since I shut the system down last week for a few minutes and
restarted it. Thanks to all who replied... but... it sure would be
nice if some knowledgeable person would just answer my original
question regarding the location of the high pressure switch (without
the "sales" pitch or warnings of doom, etc...).

That "knowledgeable person" your looking for is usually a service tech
that gets paid for what you are asking.
You paid nothing. You got nothing so stop your bitching. If you want
faster, friendlier professional service, whip out your piggy bank and
pay someone.
