When to Call a Professional

Call a professional technician if you find burnt or damaged components in the motor controller or main board, if wiring appears professionally spliced or modified, if the error persists after checking all connections, or if you're uncomfortable working with electrical components. Also contact a pro if the treadmill is still under warranty to avoid voiding coverage.
