Well, if the electronics are going to simply fail for no apparent reason, it will either happen right in the beginning or after many years of service. Be glad it failed under warranty -- the repairs can cost big bucks. I heard of one local mobile RV guy charging a minimum one hour ($110/per) regardless of how long it takes to fix something (less than an hour, that is). The boards aren't cheap, but by the time you add on two trips and two hours of service time plus parts, shipping and handling, it adds right up.
