Service & Warranty Information

How to Get Service Under the Terms of  the Limited One-Year Warranty

When you suspect an item is defective, please check the operator's manual for standard operation and trouble-
shooting techniques that may correct the problem.  Additional information may be found on the M.T.H. Website.  
Should you still require service, follow the instructions below to obtain warranty service.

First, e-mail, write, call or fax a M.T.H. Authorized Service Center (ASC) in your area to obtain Repair 
Authorization.  You can find the list of  ASCs on the M.T.H. Website, www.mthtrains.com.  Authorized Service 
Centers are required to make warranty repairs on items sold only from that store; all other repairs may-- or may not 
be done at the store's own discretion.  If  you did not purchase the item directly from the ASC, you will need to 
select a National Authorized Service Center (NASC).  These centers are compensated by M.T.H. to perform 
warranty service for any customer whose repair qualifies for warranty service.  A list of  NASC retailers can be 
located on the M.T.H. Website or by calling 410-381-2580.  Should the warranty no longer apply, you may choose 
either an ASC or NASC retailer to service your M.T.H. Product.  A reasonable service fee will be charged.

CAUTION:  Make sure the product is packed in its original factory packaging including its foam and plastic 
wrapping material to prevent damage to the merchandise.  There is no need to return the entire set if  only one of  
the components is in need of  repair unless otherwise instructed by the Service Center.  The shipment must be 
prepaid and we recommend that it be insured. A cover letter including your name, address, daytime phone number, 
e-mail address (if  available), Return Authorization number (if  required by the service center, a copy of  your sales 
receipt and a full description of  the problem must be included to facilitate the repairs.  Please include the 
description regardless of  whether you discussed the problem with a service technician when contacting the Service 
Center for your Return Authorization.

Please make sure you have followed the instructions carefully before returning any merchandise for service.  
Authorized M.T.H. Service Centers are independently owned and operated and are not agents or representatives of  
M.T.H. Electric Trains.  M.T.H. assumes no responsibility, financial or otherwise, for material left in their 
possession, or work done, by privately owned M.T.H. Authorized Service Centers.

If  you need assistance at any time email MTH Service at [email protected], or call 410 381-2580.

an item can be verified on the item's detail page “shipping date field” on the M.T.H. website (www.mthtrains.com).  
This warranty does not cover damages caused by improper care, handling, or use.  Transportation costs incurred by 
the customer are not covered under this warranty.

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

you are sending this product to an Authorized Service Center, contact that Center for their return authorization.

This warranty gives you specific legal rights, and you may have other rights that vary from state to state.  Specific 
questions regarding the warranty may be forwarded to M.T.H. Directly.

* 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.
