Everything was fine, registers were blowing heat and temp was rising. Fans were on at the registers and the diesel burner was firing. About a half hour in I noticed the cabin had filled with smoke. Not a crazy amount but definitely enough to cause more than a little concern. I shut down the furnace at the HVAC control and the diesel burner. No obvious source inside the coach. Checked basement and Oasis compartment and found nothing of concern. Anyone have any insight into this? Thanks.

You mentioned that you had been running the heat pumps. You might want to see if the heat pumps and AC are still working. My coach filled with a smoky haze one night while running the heat pumps. At first I thought there was a fire, but it did not set off the smoke alarm. I aired out the coach & could not figure what caused the haze. The following morning neither the HP or AC would work. It was then I realized that the rear HP had dumped its refrigerant into the coach, causing the haze. Had the unit checked & sure enough, no refrigerant. A few weeks later the front dometic AC also failed & lost its refrigerant. This time it was expelled outside instead of into the coach. Not impressed with dometic quality!
