We have just gone through this with our 2006 19 Bambi...three tries to ignite after the blower come on, then goes to an "ignition lockout" mode indicated by a red light flashing 3 times a second behind the grille, and then the blower stopps. We, too, could reset the furnace by turning the thermostat off, lettng it rest a few seconds (and the red light stops flashing) and turn the thermostat back on to repeat. (Wealso reset it with the switch on teh furnace place, too, but found it was not necessary if you turn off the thermostat...it resets itself.) Sometimes it would ignite within 3 tries, sometimes it would not....but it was clear that it was struggling to ignite...rapid click-click-click-clicking noises rather than igniting almost instantly like it's supposed to.

Our situation was compounded by the fact that the LP gas detector (located right next to the furnace) would frequently go to the yellow light "fault" mode with a single "beep" when the furnace would try to ignite...

This just started happening all of a sudden during a recent trip where it was in the high 20s at night...and it started in the middle of the night (of course...nothing like a shrill beep to rouse you in the night...I guess that's why they are shrill)... During the day and early evening it was hit and miss...sometimes the furnace would ignite in three tries, sometimes it wouldn't.

Fortunately we had the heat pump to gve us some heat during the mornings and evenings, but it was too cold in the dead of night for the heat pump. The dogs and the comforter had to do.

We dropped it off at the dealer on our return from this trip...and of course, they couldn't duplicate the problem. So we brought it home 3 days later, quite frustrated with whole thing. WE decided to watch a movie in the Bambi that night to test it some more...and it started it again that night. We could still get it to do it in the morning...so we called the dealer let them know ti was happening again, and were going tobring it back and stay there until they figured it out! We were releived that we were able to demonstrate the problem this time when we got there...

They jumped right on it. Because there was a problem igniting and it was struggling, even with it did ignite—and it happend during colder temps—the tech suspected the LP gas regulator was on the fritz...we had not run out of LP gas, however...we have the auto tank switch-over. They tested the gas pressure and found it was inadequate, therefore not delivering enough gas to the furnace to comlete ignition... So they replaced the regulator and the pressure returned to normal... They tested each of the gas applicances individually to make sure they were firing up quickly, then all of them at once..and they all worked perfectly. (We had been having trouble getting the oven pilot light lit, but we thought it was just us and its awkward position...nope...it was the low pressure all along! Now the pilot lights reasonbly quickly!

Then there was that LP gas detector going to yellow... The yellow light indicates that it is not getting enough juice. They replaced the detector to be safe, but when they were installing it, they found there was no power to the new unit... All the fuses were good and all circuits were hot, so they took off the cabinet panel to inspect the wiring leading to the detector... and found a loose wire and fixed it...we figure it was getting adequate power some of the time but not all the time, and that the heat and/or vibrations from the furnace were causing it to expand/contract or connect/disconnect, thus making it seem like it had something to do directly with the furnace, when in reality it was a completely separate and different issue.

We learned a lot today, and the tech at Oasis RV, René, was really very knowledgable, helpful and willing to explain what he was doing and what he felt was going on...and how it was gonig to be remedied. They really jumped on it and got it resolved...we are pleased. Particulalry, since we are leaving a couple days after Christmas for a 2-week trip, and we will have some cold nights!

Annie and Sadie (our cockers) will be happy, too...the clicking of the failing ignition scared them something awful, just like the beeps and chirps from detectors do. We are going to have to desensitize Annie to the furnace kicking in on this trip...she's now afraid of it...

I'll let you know if we have an recurrence of the problems, but I am thinking they are fixed...the furnace has been running all evening with no failures.

TB,

If you go back to post #10 in this thread, you will see that we also had to replace the regulator. All I can say is, now watch for a sticking sail-switch!

Yup...now I'm keeping my fingers crossed that we will be good for a while...always sorta waiting for "the other shoe to drop"...If it does at least I'll know what to suspect, and maybe then I'll take youir lead and get my screw driver out and whack the furnace into submission!

Thanks!

Ease on..ease on down the road...

Thanks for the post TB....I think I'll take mine in for repairs. I tried to fire my furnace this past weekend and the only way I can get it to light is to bang on the regulator while the ignitor is clicking. I thought the problem had resolved its self, but no such luck.

A note about Sail switches. In our trailer, the more lights we have turned on the slower the blower spins, to the point where it is not spinning fast enough to trip the sail switch, adn the furnace will go out. As you turn off the lights the blower will spin faster, and the burner will light again. This is even with a fully charged battery. Newer trailers may not suffer this condition, but it's something to consider.

Check the output of your converter. You should be able to power the furnace and lights!

I had this problem exactly, and I did a lot of research, mainly here on this board. I finally decided that my problem must be a bad propane regulator, and I replaced it. I did not use the Marshall unit that seems to be the default piece to use, but used the Cavagna regulator that several posters liked. It costs more. One thing I've learned over half a century of buying photographic equipment, audio equipment, computer equipment, and now Airstream goodies, is that the cheaper part is ALWAYS cheaper for a reason. It's staggering how often this proves to be the case. (down from the soapbox) Anyway, My stove lights faster, my furnace worked on the first try, and my fridge switches to propane almost immediately. I took a diagnostic shot, and it paid off. Doesn't always work that way...

Thanks Lewster, That may well be the case. the converter is original to the trailer. I'll check it out. George.

Well I took this in and had the gas regulator in the furnace replaced. Turns out my problem was at the furnace. According to the tech, there are two valves in the thing that gas flows through, and one of mine was bad.

Thanks for all the input on this issue.

Bill

Correct!

As a safety feature, any furnace is required to have redundant gas valves (2) so that if one fails to close, the other one will......saving a potential disaster.

Glad you got it fixed! So now there's another thing to check when the furnace won't ignite properly...thanks for letting us know what was going on... and adding to the accumulated knowledge about this problem...

Now you can be all cozy and warm!
