Chris - Thank You also - I did communicate with Ernie Santiago - svc mgr - I think they want me to send it in - but I've learned that the warrantee is only 90 days on these, so mine may not qualify - however all three of them have been purchased since 2009...
I asked about repair cost - worst case scenario - says it could range from $200 - $50...Don't know if that means they usually charge $200 - but maybe as little as $50 - but if it's $200, I'd just as soon put another $130 with that and buy a brand new one - sell the used one for $130 - still works fine for a small room - just not as powerful as the other two....
