Have you traced the circuit and know for certain they are in the line and
neutral sides of the primary? Could they be in series or parallel in the
same line side feed? What are the values of the two components? Obviously
from the photo one is much larger so I would assume will be for higher
current/power, but possibly the thermal constants could be different and the
combination in parallel may give a better in rush current curve or possibly
protect against the problem I saw with the single under-designed device. I
guess I am just wondering if the second part wasn't a "fix" to a known
design problem

Travis,

Per your request to post a follow up, the CL40 part arrived via UPS today
and although about 4X the physical size, installed without any problem and
the unit is working once again. Thanks again for the advice. Let's hope
that doubling the current capacity will prevent a reoccurrence.

Congratulations on a good repair, and you are very welcome.

Enjoy the holiday weekend.
