Landcruiser Posted January 10, 2021 Share Posted January 10, 2021 Hello, Thought someone might be able to steer me in the right direction, or have the answer. I have a DFSD20111 furnace that just started blowing cold air. The control board blinks 2 times then pauses for 3 seconds. This indicates a hard reset so I pulled the fuse to reset it. Same problem. I then purged the LP to confirm gas. Same problem. I called Oliver and Dometic but its Sunday and I can't get any tech support. Thinking it might be the igniter, was going to start checking for power at the connectors, then maybe remove it and check continuity. Any thoughts, I'd like to at least find the problem today. Thanks, Peter Link to comment Share on other sites More sharing options...
