MAYBE it's simply because it's so hot here (10mi north of NYC)
that everyone's running their own AC's, that the voltage is down?

(Once I checked with one or several VOM's -- seemed ok to me.
But I'll try again after posting this, just to get a general
discussion going.)

How low should the voltage get to cause such a try-try-try problem?

Also, in the last "n" years, have the AC manufaacturers tried
to build around the "everyone's running their AC's and voltage
is a bit (a tad) low"?

If so, about when did that change take place?


THANKS!

You can install what is commonly called a "kick start" unit in
the condenser control box. Most AC condensers don't have a start
assist device from the factory although it's an option. It could
be that your AC is trying to restart before the system pressures
have time to equalize. An anti short cycle timer can solve that
problem and also keep someone from playing around with the thermostat
and slamming the compressor on and off. The time delay is usually
set for 3-5 minutes.
