Our Norcold 1210 worked fine at home. When we got to the campsite, the L1 oP code popped up. Of course, we were in a state park with no internet. Reservations for four days camping along side a beautiful lake, so didn't feel like going home. We bought 3 22 lb bags of ice, and used most of it in the freezer and refrig. Got home today and checked the users forum and found the link to the same problem on the Heartland forum. Held my "pickup tool" magnet just underneath the red light for around 30 seconds, then heard a slight snap from the black box directly below the limit switch box. Refer is back on! Thanks to the forum for providing valuable information!
