If you return your motor for Trade-In, the replacement charge is 58.00 plus return shipping. You can request the same wind motor, or get a different wind for the same price. When items are returned for replacement, we simply send the customer the item requested, we do not examine the returned item to diagnose the problem.
You seem to be asking to return your motor for evaluation only, for which we charge an evaluation fee. We cannot diagnose an item without seeing it, so I'm not exactly sure what you want us to do about a year old motor.
You can email Charlie,
[email protected] and he may be able to help you narrow down the part that needs replacing. You could then replace the part and not need to return it for service; every part you need to service your motor is readily available.
