Just bought a 2021 RW with a Furrion oven, F1S21L03A. The LED around the oven knob is red. Manual shows a fault code of a sensor problem and to contact dealer for service. Dealer said to call Furrion direct (of coarse), Furrion says the only way that happens is if it was wired up with reserve polarity, I need to contact Heartland (of coarse) to have it replaced and rewired. Heartland says they contacted Furrion and they will send me the replacement part to install myself (not surprised). I asked about rewiring and Heartland is saying nothing needs rewired, just replace what ever part they send me. I am still waiting on the part so no idea if it will work. Anyone had anything like this before?
