Please be advised that, as a small business, we generally do not accept returns, except in extremely rare instances such as a product malfunction or being damaged upon arrival, which occurs in less than 1% of new parts. Due to the nature of our business, which involves selling new, unused parts, we incur a total loss on any returned (even if they were "not opened") items. Because unlike large corporations That can absorb returns we have no way of doing so. Once we purchase our Parts, All sales are FINAL from the vendors. Therefore, it is crucial to confirm that the part you are ordering is the correct solution for your issue and your exact model appliance. Unfortunately,  We are unable to oversee this process, and we encourage you to contact us with any questions to ensure accuracy. Returns can significantly impact small businesses like ours, as we are unable to return parts to our vendors. Once a part is received, returns are impossible. We also are tasked with trying to limit the number of thefts  through "part swapping" which has become the number one way of trying to get parts or items for free.  We do take video and extra pictures with our unique water marks on each part to ensure we do receive the original part we sent to the customer back to us.  But even then,  we unfortunately,  still have to prosecute to the fullest to ensure all of our honest customers continue to receive Brand New Oem Unused parts.  We appreciate your understanding and are committed to ensuring the best possible outcome for both you and our business. Thank you for considering a purchase from us; we look forward to assisting you!🚨🚨
