Since we manufacture the Excalibur here in the U.S.A., we have replacement parts on hand, if a component of your dehydrator is accidentally damaged. While we can't guarantee that we have everything, we even have some parts available for models that are 15-20, or more, years old. If you need parts, accessories, or service you can order them online or call toll free 1-800-875-4254. We'll need the model number of your dehydrator and associated details for the parts or service needed. If you are requesting a repair that's covered by our warranty, we will also need confirmation of your purchase date and a copy of your receipt. For further information on warranty, please see above. If your repair is not covered by our warranty and you need help repairing your unit you can ship your unit to us and we will repair it for a modest labor fee plus the cost of parts. Call our Customer Service Department for an estimate. If you would like to fix the unit yourself and need technical assistance, our Service Department can walk you through the repair for a .00 technical service fee.
