During the summer heat the location may exceed the 145 degree F max limit for the Balmar MC-624 LN unit. This unit is no longer in production and replacements are limited.
Balmar makes a MC-624 regulator which seems to do the same function but with different connectors, so some modification may be required.
I am thinking about moving the regulator to inside the closet to reduce ambient temperature.
I would absolutely move it and perhaps even add a small (computer fan?) fan that is thermostat controlled. I'm with you, it sounds like the extreme temps are greatly shortening its life.....
