Dometic Fridge not cooling

I have a Dometic RM2652 that has recently stopped cooling on electric or gas. When switching the unit from 120v to gas, the igniter works but no gas to light. I can tap on the top of the black solenoid that sits on to of the brass gas valve - at this point gas passes thru and the pilot will light but after about 5 seconds there is a click and the gas stops. I tried another solenoid but still had the same problem. I can light the stove in the kitchen and it lights and runs fine, telling me there is sufficient propane.
Any input and/or suggestions would be greatly appreciated!
Thanks!
Steve

    Check the 12V DC voltage at solenoid when spark electrode is 'firing'
    DC is only on solenoid for 6-8 seconds during ignition cycle.
    Main flame has to light off and 'PROVE' it lit during that time or circuit board drops voltage to solenoid.

    Spark electrode MUST be directly engulfed in main flame to prove flame lit


    See pg. 8 etc for tests/troubleshooting

    If not, then quite,likey the control board is bad. Dinosaur boards are reasonable and better than dometic boards.


    No strange smell and no residue anywhere. I will check out the dinosaur board. Thanks for the info!
