I bought a brand new Nautilus T518 in June 2009. I used it consistenly (12 – 15 miles per week) for 7 months and it STOPPED working. The internal circuit breaker would flip and the power would cut out.
The retail store sent out a repair guy and determined the transformer was overheating. They ordered a new controller board from Nautilus. Three weeks later the part finally arrived and the service guy installed it. After running on it for 5 minutes the same problem happened.
This machine is junk and the manufacturer doesn’t care how long it takes to send out replacement parts.
