Guys,

I just did startup on three Trane split HPs with low ambient kits. I was
called
in because the tech who was there doing it said his compressor was "surging". I
get
there and get a few things fixed up and started the check out (outside ambient
is
below 70 degrees F). The condenser fan is cycling on and off, 3 seconds on, 3
seconds
off, which basically is causing the fan to speed up and slow down continually.
I
thought to myself, "Now that's different" and got out the installers guide and
sure
enough that's how it's supposed to work. OK, is it just me or does this sound
like a
bad idea? I am a big fan of Trane equipment but this has got to be hard on the
fan
motor and the relay(s) involved.

Ive never seen a compressor "surge" in all my days yet. He sounds like
an idiot.
Condenser fan on and off 3 seconds at a time. You cant read or you've
been smoking something. Point me to what/where you read so I can see
it myself.

Somethings wrong no doubt... 3 sec on/off...
That shit wouldn't last long and I thought you couldn't stop a trane. :-)

The surge was the fan reving up and down.

I don't smoke but I will drink on occasion.

This was 7 am and I read it in black and white in the installer's guide (at
least
twice). I'll get a copy of it and post it. I wouldn't shit you guys... :)

It's just the way it is designed, no kidding.

Another thing I thought was odd is that these HPs have a filter/dryer
installed
6 inches from the compressor on the discharge line. I was taught not to do
that...
What's going on??? Was there a meeting I didn't get invited to, where these
things
were thought up???

That's not a filter/drier, it's a muffler.
