You can check a varistor on a curve-tracer. They are cheap and
usually easier to just replace.
My E-12 has NEVER welded contacts. Kids have driven it; they have
gone forward/reverse without braking or slowing. I am not recommending
it, but it has not been a problem. The contactor (I'm not sure if
you welded a contactor or relay...) may have a physical problem, such
as a bad spring or have jumped off of it's rocking mechanism, or even
be bent. At the same time, I too would look at electrical problems
first. The step-by-step guide in the Homeowners Service Manuel may
give you other ideas.

Dave, "Knock on wood" I've never had a fried relay on my E-12. you must
be unlucky or something. Yes, the varistor is a device to absorb
voltage surges when working correctly. Its probably easier to replace
it than try to check it without special equipment. Also, a diode across
the relay coil will shunt voltage spikes - just be sure the diode can
carry the current generated, they usually blow open and you lose
protection.
