Had a to replace my failed processor board in August 2008 after 2280 hours of operation; hit me for $350. 
Then in January, the replacement board died 288 hours and 5 months later!
The FuelMaker rep sent it in for diagnosis and requested a refund, which he got, and passed back to me (fortunately).
I think these are temperamental to power outages and the like.
So now I turn off the power after each use. I looked into a 220 VAC power protection unit, and found one in excess of $300 - think I'll just save my money and kill the power.
If anyone knows of a less costly power protector for a 15 amp 220 VAC circuit, please pass the info along to us.
Thanks
