    Not sure what you mean it does nothing? Does the transformer hum when you turn it on? Have you tried to jump the trigger to see if its just a bad trigger? This is fan on demand so the fan will not run until it heats up but you can jumper a relay to see if the fan runs.. Need more info.

    On the inside, above the drive rollers there is a little white button, It's the CB1 reset try pushing that.
