Perhaps you all should read the MTH warranty
The following is right on the bottom of the page
* Authorized Service Centers (ASC) are only obligated to provide warranty service for any consumer who has purchased the specific M.T.H. item from them that requires service work.
Thank you for the clarification as it has been a couple of years since I have needed MTH service. The last time I had warranty service done was by a different MTH authorized service center who kind enough to do the needed repairs and was not the dealer I bought the item from.
M.T.H. products manufactured within five years from the date of purchase are warrantied for one year against defects in material or workmanship, excluding wear items such as light bulbs, pick-up rollers, batteries, smoke unit wicks, and traction tires.
Items sent for repair must be accompanied by a return authorization number, a description of the problem, and a copy of the original sales receipt from an M.T.H. Authorized Retailer, which gives the date of purchase. If you are sending this product to an Authorized Service Center, contact that Center for their return authorization
