Is it possible to repair a whole house surge suppressor?

At 100 to 200 dollars, I don't want to keep buying new ones.


I was going to install a whole house surge suppressor. When one of
them does its function, I think the MOV burns out, or some part does.

I haven't seen anything on the web about replacement modules for even
those units that might have them.

Will I be able to find, buy, and solder in replacement MOVs after the
first one burns out? (the green led goes out and the red led goes on)


I can't find any info about plug-in replacement parts, so if I can
repair any unit myself, I won't have to shop so thoroughly.


Items for sale, if interested:
I can install it myself. I'm considering, in ascending price order:

and less likely (plus two are required, one for each leg)
