Inquiry (采购产品): Heat pump cords we are using your RAK 3203 cords with our GE Heat pumps and have had repeated problems with the cords tripping off. This has happened on several units and several cords since this summer. One of them got so hot it turned black! Are we doing something wrong? We'd like to get them replaced... Is there any warranty at all? **** Hidden Message ***** Charles Glaser 45840 Company: Glaser Apartments E-mail: glaserapts@bizwoh.rr.com **** Hidden Message ***** glaserapts@bizwoh.rr.com
