Norcold 682 propane lockout?

Hi
I have a 91 Winnebago on a Ford F53 chassis. My Norcold 682 works fine and cools on AC but I cant get it to function on propane. The 12v appears normal and the fridge goes through the attempt to start. I have made several resets and the board shows LP then the red X after a while. I have gone to LP and back to auto and then several resets. It is like the propane is not flowing. I have removed and cleaned the tubing and checked that there is flow through the orifice but no luck. The unit worked fine on both systems prior to this year and it has not been used for a while. I had this problem in the past and when I used the reset procedure before it always worked. Any thoughts would be appreciated.
  • If yo look online you should find a step=by-step trouble shooting guide form Norcold. I have fixed several

    Here is a link
  • Our Norcold ( different model) no gas operation - it was the circuit board. Sympton seemed like there was no propane when there was to everything else. Full charge on the battery and 12 volt was good. We could hear the gas valve open, but then no attempt for lighting and we could not smell any propane.
  • Ok, sorry but I have to ask. Do you have enough propane in the tank for it to flow? Do the stove burners ignite?
    It's possible your LP solenoid on he fridge isn't working. Maybe give it a tap and see if it starts flowing. Had that problem with a furnace one time. It wouldn't lite. I tapped the solenoid and it worked fine after that.
  • My sister-in-laws fridge did the same thing. I can figure a lot of stuff out, I did everything I knew to try, finally called in a buddy who is a certified RV tech.

    Sounds crazy but the final result was the cooling fan on her 120/12 volt converter had failed. The converter was over heating and dropping voltage. Without the full 12+ volts the propane solenoid wouldn't open.

    I put a new cooling fan on it and it was fixed. That was 2 years ago and its still going strong today.
