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?
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,
