Description for Use

Please note that many circuit boards look the same. Therefore, you should always match your existing circuit board's chip number to the replacement before you place an order. You can locate the chip number by looking for it on the white sticker in the middle of your circuit board. In the off chance that your board does not have a chip number, or you'd just like to make sure you're ordering the right replacement part, simply reach out to an MSP product expert at any time. You can also talk to our customer support team by dialing 855-308-2149.

Shipping & Returns

Shipping and Delivery

Free shipping is available to the Continental United States. Orders typically ship within 1-2 business days. If parts happen to be backordered (which is very rare), they will ship within 5-10 business days. If you need something shipped faster, please contact us and we will do our best to accommodate.

All factory parts orders are charged at the time of order. For next-day/two-day shipping, orders must be received prior to 3:00pm CST (and will not be processed on Saturdays, Sundays or Holidays.)

Returns & Replacements

Parts must be returned unused and within 30 Days of Receipt. Electronics are non-returnable.** At time of receipt of returned parts, you will receive a refund less the restocking fee.

Restocking Policy: Selecting replacement parts can be difficult, so you will never be charged a re-stocking fee if you call or email to ensure you are placing the correct order. Customers are responsible for paying the shipping costs on all parts that are returned due to incorrect ordering. A 20% restocking fee will apply on a case-by-case basis.

Please fill out the return order form on the back of your original packing slip when returning parts. Parts should be returned to:

Master Spa Parts, Inc.
2140 W Wisconsin Avenue
Appleton WI 54914

**MSP does not allow electronics to be returned as we sell only new parts and are unable to resell electronics as new if returned. Additionally, we are unable to personally test the electronics to find out if they’re not working due to incorrect installation or internal issues.

International Shipments

Free shipping is not available on International Shipments (including AK and HI). Customers shipping outside the continental United States are responsible for any additional duties and taxes depending on shipment location and cost of goods.
