Atwood Furnace Won't Ignite

Question: I have a 2001 Teton with an Atwood model 8531-IV-DCLP that won't ignite. The blower and propane solenoids are working fine and I'm getting a 63-65 volt reading on the igniter wire using a digital voltmeter (with the igniter wire connected at both ends). Is that enough voltage to fire the igniter?

Robbie: Turn the furnace on again and go outside to the exhaust, wait for the furnace to try and ignite and when its finished smell the exhaust for propane... smell from the side-DO NOT put your face in front of the exhaust.
If you smell propane you do have a problem with your ignitors and they may need to be cleaned or replaced(call a qualified tech to do this). If you don't smell propane you have a gas supply problem or your gas valve is not opening. Test the gas by lighting a burner on your stove top and turn on the furnace when it tries to ignite the flame on the stove should remain the same, if it gets smaller you do not have enough gas pressure. Lastly to answer your question carefully remove the Computer Curcuit board and you can take it to any RV repair center and they can test it for you to be sure the ignitor is sparking strong enough. Please feel free to call me anytime if I can answer any more questions regarding the furnace.

Thanks for the Question Good Luck,

Atwood furnace won't start at all
by: Marc

My 2016 Lance has a Atwood Intertek forced air furnace that worked well for many months. Now it won't blow air at the startup or even work with the heat cycle. The 12 volt fuse is good in the dist panel. The 1 amp fuse is good in the Thermostat too. The A/C works fine. Any ideas? I'm 2000 miles from home and any Lance warranty centers.

Our solution

Finally found the solution to my problem. After replacing the propane valve, sail switch, checking circuit board, checking the limit switch, it wouldn't ignite. It turned out to be in the gas valve not getting the proper pressure to the heater. Lifted the little cap off the gas valve and inside turned the inserted screw very gently till it stopped. Do not tighten. The furnace has worked perfectly ever since.
