Heater & A/C

[rbr]

Hi all-
I have a couple of minor problems with our new-to-us 2004 Safari 28, generally in near-new condition. The heater lights only very reluctantly after many time out failures, and then the flame sounds like it is sputtering and popping rather than a steady healthy roar. Propane bottles are full and all other gas appliances work fine which I presume rules out air in the lines or pressure issues. The vent fan runs fine and no insect/rodent detritus can be seen in the exhaust vent, nor is there any untoward stench from the heat exchanger when it does light. How do I check on a valve or burner orifice problem, or is this now an issue for the repair shop? The other problem is the fan motor on the A/C, the bearings are too sticky for the motor to start by itself, but will turn and run w. a manual push. Are these sealed/replace-motor-only types or is lubrication possible (hopefully from below)?
All ideas welcome, I am a 3-4 wrench level do-it-yourselfer with all necessary tools.

On the heater the flame probably needs adjusting post the make and model.

On the ac you have a bad fan motor "start capacitor" a relativity inexpensive fix.
you need to remove the old one so you can get an exact replacement. It is a small tin can looking thing with wires going to it from the fan.
Probably something like 7.5 MFD 400VAC stamped on the can. Be careful they can hold a charge (normally ac capacitors don't but they can) to be safe take a screwdriver and short the terminals before you touch it.
In some cases there will be 2 capacitors in one can one half for the fan & one half for the compressor. Take a picture of the wiring or wright down where they are connected.

As far as the gas furnace goes, it sounds like a line or jet obstruction. Also if the outside furnace access is not screened, you may have a wasp nest in there. They really like RV furnaces.

The air conditioner may well have a bad capacitor. Look at the capacitor can. If there is any distortion in the can, that is most likely he culprit.

Sometimes you can just tap lightly on the line close to the burner to get rid of anything. I have to do this once in awhile for the ref. to light.

Be careful they can hold a charge

I'll double that one!!! Don't ask!

Thanks to those who responded, after cleaning out the mud-dauber nests the heater fires right up... I didn't realize that small fan motors like the A/C had a start capacitor but will check it out...I think the po may have been trying to run it on 20A current.
