Yeah, I've had some Main boards that failed from the caps going bad. Time can be an enemy, so if you start having problems/symptoms, it's best not to wait for the problem to stress out other parts.


My rule -- Let it get to the point it fails daily...then bring it in for service.

That's fixable. Once every month...that's something we'd have in shop for 2 months to verify the problem first.


Look at your Main board and get the Part number off of that bar coded sticker. Google it.




That will get your clicking relay problem resolved.
