Smoke from a/c unit/ heater
When I turn my back unit on to heat I get a lot of smoke from it....i get it, it's like Turning your heat on at home during the 1st cold snap at home. This heater is still smoking after letting it run for 30min...not sure if this is normal. Any suggestions??

If it's a Dometic a/c, there are a couple of covers. one of which is a bug screen about 3x4 inches forr the heat element, the other for wiring. I would suggest that you pull the ceiling panel off** and make sure that something didn't shake down and lodge between that bug screen and the heat coil. The other should be not have any real access for crud. Aby other brand, probably similar. As a note, there is very little on that coil that will burn off and cause more the a light momentary odor as I found when installing our heat coil
**The paperwork supplied with the RV should have a set of the installation instructions for tha a/c. If not, they can be found on the net. Not a tough job for someone with at least 3 or 4 hands though with only two ...

New furnaces will produce smoke for a while the first time. Your dealer may not have done a proper PDI. I have ran furnaces for 1/2 hr or more to clear up the smoke.
I would shut it off. Let it set for 1/2 hr and then try again. If it creates another heavy smoke cloud, it needs to go back for warranty service. It can take a few cycles to clear all the oils.
