If your Furrion 18K Air Distribution Box #FACT18VSDA-PS-AM is defective, you can either request a refund or initiate an exchange for a working unit. Since the part affects your cooling system, it’s recommended to order a replacement immediately to avoid downtime while the claim is processed. The defective part must be opened and used to start the manufacturer claim process with Lippert, which can take several weeks. Lippert's technical support may also assist in troubleshooting the issue. Unfortunately, Elkhart RV Parts does not send a replacement before receiving the original part; however, ordering a new unit first ensures you maintain cooling while waiting for the claim resolution.
