    need help on my atwood furnace

    I have a 23' Damon mh its old but taken care of 1995. The furnace has worked every winter as I fish hot water discharge lakes in Illinois all year. this year the fan came on when I turned it on but no heat. I filled the self contained lp tank ran it thru whole camper stove, water heater to get air out. I checked for obstructions via the exhaust and plenum. seems like no ignition. checked fuses I feel like ( I know nuttin) Its the thermostat or ignitor but don't know how to test either one Help please

    Can you run the oven and stove burners at the same time with reasonable flame? If not, it could be a propane regulator.

    Other likely problem is the sail switch that tells the system the fan is on.

    Next, bug nests in the exhaust .

    Finally the flame sensor.

    Is this original to the rig?

    Whenever one acts up, you want to turn off all power to the unit then turn it back on before trying to light it again.

    Can you hear the ignitor sparking or is it just not trying to light at all?

    Not trying at all, I have decided to take it to the shop. I have no experience so would make sleeping with my bipap a little scary but thanks for the help to all
