    WCTNZ® is to furnish new parts to a customer whose product fails within the allotted warranty period for the particular component, provided that inspection shows that such failure is due to defective material or workmanship.

    Any part supplied is warranted for the balance of the original warranty period based on the respective manufacturer’s warranty

    The warranty period for a part begins from the date the original product was dispatched, plus 5 additional days for transportation

    All faulty parts are to be returned to WCTNZ®; shipping of these is the customer’s responsibility unless otherwise agreed

    If a warranty replacement part is sent out and the original part is proven not to be faulty, the customer will be charged for the replacement part
