If your control board stops working in the next 6 months we will replace it for free! Simply, return it to us. If we have the same item in stock, or a cross-reference part number, we will send it out the same day you contact us. We may not have a replacement board in stock. In that case, you will receive an immediate refund for 100% of the purchase price, less the cost of the extra warranty. (Unless, the warranty request is within the first two months of the purchase date). It’s that easy!
