Query: Great for first month-then died!!

I have had the Dynatrap 1000 for a month. I left it on continuously and it worked great on our mosquitoes in South Georgia. After a month, the fan stopped working. I did what the manual instructed, but no luck! I tried to contact the company and still have received no reply. This is disppointing. My neighbors were going to purchase one....but not now.
