Issues with Norcold 982IM fridge in 1997 Tiffin Allegro. Won't work on AC or LP. Setting to auto, fridge will start on AC, then after 5-10 seconds switches to LP. LP starts, ignites, flames and then quits. Cycles back to AC, fails, back to LP, fails, etc.
When manually setting to AC, fridge will tone, flash and indicate an A4 error.
Checked converter and is working. No loose wires, all fuses tested and working. RV plugged into shore power, outlet has 120vAC, power board has 120vAC. Checked DC at board and is receiving 12vDC.
