Return Policy

Appliance Depot Inc. Return Policy

Effective Date: February 24, 2026

At Appliance Depot Inc. (ADI), we stand behind the quality of our products and want you to shop with confidence. We accept returns and exchanges only for parts (new, used, scratch & dent, or mechanical). New appliances are non-returnable and non-refundable; they are covered solely by the manufacturer's warranty. Any issues with new appliances must be handled directly through the manufacturer, and returns or exchanges for appliances are decided exclusively by the manufacturer.

General Return Guidelines (Applies to Parts Only)

  • Return Window: You may request a return within 30 days from the date of delivery.
  • Prior Approval Required: All returns require a Return Authorization Number (RAN#). Contact us by email at buy@appliancedepot.com or phone at 651-454-5995 (Monday–Friday, 8:30 AM–4:00 PM CST) to request approval and receive your RAN#.
  • Condition Requirements: Items must be returned in original packaging, with all stickers/labels intact, and in resalable condition (unless the return is due to a defect).
  • Return Shipping & Costs: Customers are responsible for paying return shipping costs. These vary based on item size, weight, carrier, and location — typically ranging from $20 to $200 or more for large/bulky items (contact us for a specific estimate before shipping). Original shipping and handling charges from your purchase are non-refundable.
  • Restocking Fee: A 30% restocking fee applies to non-defective returns. This fee is waived for verified defective/DOA (Dead on Arrival) items.
  • Refund Details: Refunds cover the product cost only (after any applicable restocking fees) and are processed to your original payment method within 7–10 business days after we receive, inspect, and approve the return.
  • Process Timeline: Once you receive your RAN#, ship the item within 14 business days. Clearly display the RAN# on the outside of the package. Packages without a visible RAN# may be refused (at sender's expense). For refused deliveries, contact us the same day to verify; a 30% restocking fee applies in such cases.

New / Used / Scratch & Dent Parts

  • New/unopened parts are eligible for return (customer pays return shipping) minus original shipping charges and the 30% restocking fee.
  • Special order parts are non-returnable.
  • Used/scratch & dent parts are sold as-is and may have cosmetic blemishes but are fully functional.
  • New electric/mechanical parts are covered by the manufacturer's warranty; contact us for exchange details (no refunds for these items).

Defective / DOA Returns (Mechanical Parts Only)

  • All used parts include a 30-day warranty against DOA.
  • Report any issues within 30 days of delivery to obtain a RAN#.
  • No restocking fees or return shipping charges apply to verified defective/DOA returns — we cover the resolution process.
  • Returned parts are tested; if confirmed defective, we provide an identical replacement (no cash refund). If the part tests as working, it will be returned to you at your expense.

Appliances (New)

New appliances are non-returnable and non-refundable. They come with the manufacturer's standard warranty only. Any defects, issues, or warranty claims for new appliances must be handled directly through the manufacturer. ADI does not accept returns, exchanges, or refunds on new appliances — all decisions regarding returns or exchanges are made solely by the manufacturer.
