Return Authorizations

Customers and distributors must submit this form when returning a component for updates, modifications or repairs.

Whenever you return a part to Hamilton for modifications, repair or updates, we will issue a Return Authorization (RA) Number so your packages can be tracked and accounted for within the Service Department.

NOTE: Those units not under warranty are subject to a $85 bench fee. This fee will be waived if there are any repair charges. 

As soon as your request is processed, we will email you an RA number. The number needs to appear on both the parts being returned and the boxes they are shipped in.

When submitting your request between the hours of 8:00am-5:00pm Eastern Time weekdays, we will send you the authorization number via e-mail within one (1) hour of its receipt.

If you do not get a response, please contact Hamilton Support at 419-867-4852, or email

After hours and weekend requests will be processed on the next business day.
