I have a Bryant Coastal unit that had a cap replaced under a year ago. The unit failed again. I was told that the cap was o.k. but that the wires to it had melted and thus the cap had to be replaced. They theorized that it may have been due to a surge.
The electrical service has a Leviton whole house surge protector that is showing green. I'm wondering if the cap insertion spades were not crimped tightly and it arced or whether it is due to a bad Chinese capacitor.
What probably caused this? Should I upgrade to an Amrad capacitor to prevent further issues?
