RV Furnace Won’t Light In The Rain

So now that we’ve got owned our new RV for an entire week, we got here throughout its first drawback, the RV Furnace wouldn’t mild when it was raining. On the plus aspect, we had been solely tenting out in our driveway, ready to see if there have been any points earlier than we took it out on the highway.

After it stopped raining I pulled the surface cowl off the RV furnace to see what was occurring, and located a puddle of water within the backside of it. Awesome.

The puddle of water runs to the again of the part space of the furnace, and truly into the hearth field of the furnace. When the furnace would attempt to mild i might hear the fuel flowing and the ignitor sparking, and it might generally hearth for a second or two, however the flame would sputter and exit.

When the blower would kick on it was blowing the water round within the firebox dowsing the flame and inflicting the furnace to not mild, or exit proper after it did.

So step one of many repair is to get all of it dried out. I used a warmth gun to pump scorching air into the firebox by the exhaust tube. If you don’t have a warmth gun, a hair dryer will work as properly.

After getting it good and dry, I took a journey to the house enchancment retailer to get one thing to seal the underside of the firebox space so hopefully that is solely a one time headache.

Glad I did as a result of once I obtained again I discovered that extra water had seeped out of the firebox and it should not be utterly dry inside. So again to the warmth gun for a bit.

After I used to be positive it was good and dry, I turned the reset swap again on, and let the furnace attempt to mild. It lit as regular, so I went and obtained a contemporary cup of espresso, then got here again outdoors and turned it off. Then again on, sip some espresso, lights good, shut it off. Then again on, sip some espresso, lights good, shut it off. You get the concept right here. Now I’m positive the water was the problem and we’re good to go ahead with the everlasting repair.

Grab the fireproof sealant that you simply picked up that’s made particularly for the sort of software.

The exhaust tube was longer than the caulk nozzle, so I added a chunk of rubber hose with a view to attain the realm the water was seeping into the firebox.

All sealed up so water can puddle up and make its manner into the firebox sooner or later.

Pro Tip: Turn the furnace again on earlier than placing the surface covers again on. Then you possibly can skip the step the place you go inside and crank up the thermostat and nothing occurs, and should take all of the covers again off simply to flip the swap on.

Hope this helps somebody someday, in that case tell us!
