Half of the switches in the panel are connected to the same leg of the
generator. Since everything else works, my guess is the switch. It's a
single pole double throw, center off switch. It's possible the connection
from the gen to the common is dead. It's also possible that the unit has a
bad fuse, or breaker for that switch



Actually, two circuits that definitely worked, the Sump Pump and the Master
Bedroom, are both on the "B" circuit. The Refrig was on the "A" circuit,
and now I'm remembering the Family Room, also on the "A" circuit, was not
working either.

If half the switches connected to the same leg of the generator were
working, and the other half not working, what problem would that suggest?



It would suggest that you call the electrician who initially installed the
transfer switch.

While time has elapsed, the transfer switches most likely havent been
operated
enough times such that you see this kind of failure. Surely you haven't
been
operating them 10 times a day for 2 1/2 years.

This is an abnormal early failure.
