Furnace fan wont turn on 2001 Angler 8C

Still trying to post pictures. Took it out just recently for 6 days in the dezert. The heat (furnace) was working fine. Came home to unpack yesterday and check everything. I tried to turn on the blower motor for the furnace by using the little on and off switch behind the metal grate, like I was doing while camping with no issues. I checked all the fuses in the fuse block that is attached to the circuit breaker panel. The fuses look good and I even tried turning off and on the circuit breakers. Still nothing when I turn the switch to on. Is there a separate fuse or breaker within the blower fan box? I do have the power cord of the camper plugged into an AC plug. The battery in the camper is charged. Thank you for any effort on this issue.

    Make and model of furnace?
    What is thermostat set at?


    Thank you for the quick reply. I am at work, when I get home today I will get the make and model. I didn't have the thermostat on. Now would that make it not turn on? If you see my intro a couple weeks ago, I am very, very new to Campers. again, thanks brother.

    Yes, without thermostat, the furnace is not told to come on.
    Switch is there for maintenance safety. Turning it off shuts down furnace power so it doesn't come on when your fingers are in it.

    Ok thanks again for the quick reply. I did have a picture on my phone. It is a Atwood, Model 8012-11. Ok when I get home I will turn on the thermostat and start it our at 75? obviously the little switch on the furnace should be on too? Like I said it was working when I was camping, but being new to everything I can't remember how and when I did it.

    Switch on furnace is dual purpose...It is On/Off for using when working ON the furnace (turn it off then it can't start accidentally)
    It also is a Circuit Breaker that can trip if high amp load is sensed when using furnace

    Normally that switch should be ON & Reset

    Thermostat is the 'switch' that turns furnace ON
    Set thermostat to HEAT Mode, Turn set point above room temp and you should hear thermostat 'CLICK' then shortly after you should hear Furnace FAN start

    Here is a better manual directly from Atwood.

    First go to page 6 and use the Model Identification to determine what model you have. Then on page 13 there is an explanation of the diagnostic LED on the circuit board. The LED flashes a set number of times to indicate the fault detected.

    I had the same issue with the Atwood in my 2002 Lance. It was working fine and then it wouldn't do anything. I was able to jumper the fan wire and get it to start so at least I knew that worked. I wound up replacing the control board and everything worked again. Here's the part I found on Amazon.

    BurbMan,
    Oh ok, thanks. I will open up the access cover to uncover the stage control board and conduct proper "start up" procedures. I will post what happens.

    I want to thank everyone who help. It was my Dumba$$..I didn't have switch on on the thermostat. But am going to make a continuity book (like we do in the army) as a step by step. Thanks again everyone, the furnace is blowing hot air again.
