Atwood 8940 Iii Dclp Troubleshooting Manual
I found that my atwood 8531 furnace would not ignite unless I pounded on the side of the furnace. After doing some research and reading many blogs I took my furnace apart and looked at the control board. Nothing was burned on it and the green light was blinking once and then again 3 seconds later. I looked up the codes and it said something about air blockage. There was nothing in line of the fresh air intake. When this happens it is most likely the sail switch. The sail switch tells the unit that there is plenty of air flow and it is safe to continue firing the furnace up. The furnace is rated to be safe and not ignite if the blower doesn't produce enough air flow(70%). The sail switch is located on the underside of the blower motor (squirrel cage) housing. The switch is held in by two screws. It has been known for these switches to burn out and not allow the furnace to work. I called atwood and they said that because this furnace was discontinued that there was no replace part listed for the sail switch. I was told I would most likely have to purchase a new furnace. I went on amazon and found this switch, Atwood 36680 Sail Switch. The switch costs me $4.95 and was sent in three days. I put this switch in and the furnace fired right up. Please do this before taking your furnace in to be fixed. This was an easy fix and saved me hundreds of dollars. Good luck. Any questions you can contact me at mmd2791@yahoo.com. No charge for what I know. Thanks
