I have a 5.5 year old 7KW Guardian powered by natural gas. After running fine during a recent 3 day power failure, the unit would start hard and immediately stall out. I dilligently followed the (excellent) diagnostic manual, but still no luck. After waiting on hold for 30 minutes, I emailed Generac Customer Service/Tech Support, and got an immediate response that I would be contacted in 48 hours. Well, that never happened, so I surfed the web and found this outstanding forum. Yep; I ordered a replacement bellows from Ziller, got it 2 days later, installed it, and everything now seems OK.

I really like my Generac; it appears to be well designed and constructed, and easy to work on. This has been the only repair in almost 6 years -a $12 part. But, come on Generac Corporation, get into the twenty-first century/information/customer-service age. Why wasn't there something posted on the Generac web site about this bellows problem? I'm not a dealer, but I am a customer. A little support would be appreciated!

To Ziller and the contributors to this forum: a heartfelt thank you.
