    I've got a Hydro Flame furnace in my 2000 Coleman Niagara Elite that will fire up about one in twenty tries. It's got the electronic ignition - no manual pilot light. Water heater and stove work fine. Anyone have any ideas as to what the problem might be? Thanks, Bruce

    I had that problem with mine once also and the dealer told me to check the electrodes for the electronic ignition and make sure the gap between them was 1/8". I adjusted the electrodes and it seem to have cured the problem at that time.

    Thanks for the tip. I'll check the gap when I can. So, when it doesn't fire up is there any other indication that its not working? Obviously there's no flame but is there also no fan noise or clicking/ignition sound? Should the fan still blow even if there's no flame? If the gap between the electrodes is too wide/narrow should I still be able to hear clicking/ignition sounds (not unlike the sound the fridge makes when starting up under propane)?

    My Hydro Flame furnace doesn't seem to work at all. There is propane (fridge and stove works just dandy) and there is plenty of 12v since I charge up the battery before leaving.

    Thank you for any insights you may have.

    You should still have fan power even if there is a problem with the gapping or with the LP system.

    As soon as the thermostat sends the message to the furnace to start up the fan starts and runs for about 30 seconds, and then the electronic ignition starts popping.

    If you wouldn't have said that it still fires up in 1 of 20 tries, I would have thought that it is the on/off switch located behind the furnace grate. You should probably still check this switch to make sure that you have power at and from the switch.

    Does it work when you are plugged in? Or does this only occur when you are running on battery?

    When the furnace is suppose to be on I get no ignition, obviously no flame, no fan and no clicking/ignition sound. On the thermostat switch the bottom lever sets the temperature from lo to hi (moving the lever from left to right). The top lever is suppose to turn it on/off but doesn't seem to move at all so I can't move it to the left (on). It was getting dark and I didn't want to force it to the left, I was afraid of breaking it.

    Am I fundamentally missing something here? Its almost as if the thermostat switch is off and no amount of sliding the bottom lever will ever turn on the furnace. I have checked and double checked the reset/off switch behind the furnace grate.

    All of this is running off 12V from a freshly charged battery, I have not had a chance to try this when I'm plugged in, I hope to try it this weekend.

    Thank you for any insights you may have.

    The switch on top of your thermostat is the issue. They take quite a bit of force to move. Don't worry, you won't break it.

    Thank you. I'll have a closer look at this when I can. I had planned on taking the entire panel out so I don't have to crouch down on the floor, that way I can have a real close up look at it.

    My wife suggested I bring the trailer to the dealer but he's 80 miles away. So 80 up, 80 back just to drop it off then another 80 up, 80 back to fetch it. Even though its still covered under warranty it just didn't seem worth my time and gas to do this.

    The fallback would have been to just buy a MrBuddy heater which we may still do.

    I'd rather replace the T-Stat with one that doesn't have that additional power switch. I agree about not wanting to haul it all that far for a Warranty Repair like this, I'm in the same boat. (Dealer an hour away.)

    My '08 Palomino just has the sliding temp control, and nothing else. The switch does 'click' though at the lowest setting. Must be the Full Off position. Hmm.

    Maybe you can just add another little switch to correct the defective/stuck power switch you already have? Just tossing out ideas here. <hr> Also on the '08, the fan will start immediately upon turning up the T-Stat. Then the heat will start eventually. After a while, if the heat never starts, the fan will eventually turn off again. I learned this when I tried to start up the furnace once with an empty propane tank. Oops!
