The milling motor stopped working yesterday on our BQ 470 perfect binder. We figured out that the breaker had tripped so we reset it and the milling motor started working again. Within a couple of minutes we got Error Code 1489 which is a thermal fuse error. The manual says to reset that breaker and if that doesn't work then replace the thermal fuse. We've done both of those things and we are still getting the error. The crazy thing is that the glue pot is actually heating up to temp, so there's clearly no electrical interruption to the glue pot. But we can't lose the error code screen. Tech support w/ Horizon and the distributor don't have a solution. Have any of you run across something like this?
