My OEM ducting was inadequate. I added 2x 4" additional ducts and the furnace works so much better with tons more heat and the burner stays on the entire cycle.

Cat hair and lint blocking incoming air?
Its just a bunch of slats in the furnace box

This will not work. The Stoves/Ovens have their own regulator set at 10 inches water column. So if the LP regulator is too high this regulator will fix that for the Oven/Stove. Doug


RV furnace gas valve also has "it's own" regulator same as a home gas furnace and even home gas stove and oven, but those also can be affected by the incoming gas pressure if it is too high or too low..

I believe OP has had this RV for a while and this IS a recently new "symptom".. If I am correct, that would make the assumption of not enough ducting not much of an issue unless a new blockage has been introduced (like a blanket covering a register?)..

OK and mine malfunctioned for almost ten years before I dug in and fixed it.

Mine seems to do this more in higher elevations. At sea level, it runs steady.

Also the squirrel cage fan can get dirty and cause it to not move enough air.

No it does NOT. It only has a 2 stage electric LP solenoid valve. But that is not a "regulator". The only appliance in an RV with its OWN regulator is the Oven/Range. Doug

probably a rech, has anyone played with the anticipation setting in the thermostate. when I got my camper it was short cycling like crazy then I looked at that and set it back yp to factory andit works good. trying to figure out what I can replace it with now that I don't have to buy from a rv shop that maybe will be a little better at the heat swing.

If you have an electronic Tstat, there is no anticipator setting. Doug
