Atwood Water Heater Will Not Light

The Atwood water heater in my 1 year old TT does not light. It worked fine last year. There is no clicking noise when I turn on the water heater power. It is a propane-only heater. There is propane in the lines since the furnace and oven both work. I checked the outside water heater fuses and both appear good (the small 2 amp fuse and the long fuse encased in a plastic tube). Any idea what I should check next?

    X2

    Also hard to visually check fuses.
    Remove the thermal cut out fuse and just wire directly to t-stat
    (Brown wire to t-stat then from t-stat to circuit board)

    Try lighting Water Heater.

    OR
    Use a voltmeter to test for DC Voltage
    12V DC to On/Off Switch
    12V DC from switch (BROWN) to 'thermal switch' to T-stat' to circuit board
    12V DC from circuit board (RED) to ECO to gas valve solenoid
    Solenoid (Black) to ground

    Are you getting propane to the heater if you are it could be the controller as I had same issue was covered under warranty.
