I recently located a thermostat that was new in the box but it had expanded, I assume, because the seal had failed somewhere. It doesn't have any physical damage and no visible cracks in the diaphram. I was thinking that maybe the solder on either the top or bottom was weak. Has anyone ever repaired one of these? I assume that it must have had a vacuum of some sort in it in order to help keep it compressed.
