I have Dometic NDA1402 model side by side RV Frig in Renegade motor home. I have a fault code Er 14 "Call" definition in the manual says (Fan I frozen food compartment faulty). I have done so far..... Hard reset (unplugged 12v for 30 min.) I have removed Freezer fan motor and jumped it across a 12v battery and it works fine. I have checked all connections and fuses around the circuit board all look good. new circuit board a year or so ago. Any one know what else to try???
