Hello CoolerDoctor,
I am having about the same problems since getting a new unit on the roof.
Everything is new except for a plug with wires for the pump to plug into.
Basically, I have a switch (hi-low cool /hi-low vent/ pump only) located in
our house, with a new 12/3 line hooked to it, that electrical line runs up
into the attic to a junction/splice box where another new 12/3 electrical line
finishes the run up to the motor/pump. I believe it is wired correctly, since
the installer just copied what was already there and I never had any issues
with the old unit shorting out/overheating. I have not checked the tension on
the belt yet, so I will do that tonight to see if that fixes the issue, but
other than that I am at a loss as to why it keeps shutting down. It's weird,
in either of the high settings it will just stop, when on the low settings it
stops then tries to start again going through various speeds to get back to
low. Could it be the old plug that is hooked up to the 12/3 line or could it
be the splice in the attic? I just don't know and would love some electrical
help in this matter.

Sincerely
Edi

You can't plug a plug into a plug. Seems this is easy to diagnose with
a volt meter when it's having the problem. If it's a new unit, who installed
it and why not just call them?
