furnace

Furnace Outlet does not line up with floor inlet Ducking. I have a Suburban SF-35 Furnace, the outlet port on the Furnace is positioned in the middle while the floor inlet is positioned to one side. Resulting in only half of the hole open. Is this a factor defect or should I notch the floor so...

Hey, I have a suburban SF-35 propane furnace in my 2011 Big Country. I’ve been having some sporadic issues with it turning on. A month ago it wouldn’t turn on unless I took the cover panel off and smacked it. So I took it out, cleaned out the intake and blower fan which had some dust but not a...

I have a 5th wheel heartland bighorn. I turn the propane heat on by pointing it at the AC head unit (it then blows through the floor vents). I also have a single slide thermostat on the wall (not sure if that does anything?) My heat turns on and it's warm. Will heat to temperature (sometimes)...

We are new to RV's... when we turn the furnace on (it does get warm)... the "forced air" fan runs constantly even when the furnace (gas flame for heat) goes on and off, so that a lot of the time the air blowing is cold. Is this normal? And it is LOUD... please advise. It seems like the fan would...

I have a 2019 Heartland Trailrunner 27RKS. The furnace stopped igniting. Heartland technical support said I need to replace the sail switch. However, I can find no way to get to it. There's no access panel on the outside. There are two fake panels to get to it. But you don't room to open the top...

Hello, I have a 2009 Bighorn 3055. After the epic Texas snow storm in Feb, I started detecting a musty smell. I took me awhile to determine it's origins, until I got close to the cold intake grille that is situated under the fridge. I did not have enough propane to keep my place warm enough...

I can't seem to locate the sail switch, and believe this is the root cause of my issues. I'm thinking it's just not making contact, and needs to be blown out. I pulled the exterior panel off, and there is no visible sail switch to be seen. I'd upload a couple pictures, but it says I have to...

So we have been staying in our camper and we replaced the propane regulator about 2 months ago and the heat was working perfect now all a sudden the heat doesn't kick on when its set to a certain temperature and just randomly kicks on an blows cold air sometimes hot. We replaced the thermostat...

I have a 2008 northtrail 31' bunkhouse. My furnace fan will start blowing and I can hear it try to ignite it just won't fire. I have looked down the vent/intake tubes and no obstructions. Where else can I trouble shoot this problem? Also my water heater will ignite an run for about 3 minutes...

Hello. I have a 2017 Mallard M33, dometic touch thermostat, and i would assume a dometic furnace (although it was not marked as such). Last night i wanted to test the furnace prior to our upcoming camping trip as we have never used the heat before. Connected to good power with 2 full bottles...

Hi everyone, I have a question about my "new to me" Landmark. I was in the rear basement (behind the sliding doors) putting in new pex water lines and trying to get them up and out of the way at the same time when I noticed that I could see the furnace. In fact i could see right into the...

Good afternoon: I tried the furnace in our unit over the weekend, to find mice had built a nest inside it. (Strong smell, and when i removed the cover under the fridge i could see some of the nest on the furnace). I would like to take the furnace out to clean it thoroughly and vacuum out the...

We have a 2017 4200 with 3 - ac units 15K each and the Suburban 35-SFQ furnace. What use to happen up until 12-4-2017 is this; The T-Stat in the hall would be set to "Auto" and the temp set to 83 the furnace would kick the blower on and heat would come out of the floor registers. When this...

Hello All, Have a 2014 Bighorn 3260EL. Having an electrical problem (I think). Here are some symptoms which are weird, and believe they may all (hopefully) be linked to the problem I am having: 1. If the light in the bedroom or the fan in the bathroom is on, the reception on our TV goes to...

I have two thermostats in our Torque 325. When I turn the thermostat to heat, (bedroom) the unit on the roof turns on an blows out cold air. Is this normal, or do I have problem? or does that thermostat not work for heat. We are also having trouble with the electric hot water heat. The gas...

I have a 2017 Lynx, took it out for the first time this last weekend to test all components and devices and glad to report everything worked well but have one question about the furnace thermostat. The furnace is a Atwood brand I believe a series AFM. The mechanical thermostat is very difficult...

I need to remove the furnace in my 21FBS. Looks like I will have to remove the refrigerator. Is there an trick to removing furnace that I am not seeing?

Yesterday, while camping on the Oregon Coast, the furnace in my '12 Big Country suddenly quit on the third day. It has been acting perfectly on every trip for two and a half years. Now it stopped. The fan comes on for about 30-60 seconds, then goes off without igniting the furnace. I tried...

So we have a new (bought this past summer) 2016 Oakmont 385QB. The nights in Virginia are starting to get quite a bit chillier than we are used to. I went to use the furnace by turning the heat on at the thermostat just inside the front door (near the bathroom). The propane is on and flowing...

Hi All! My Wife and I are new Full Timers! We purchased a Big Country 4010RD and are so far loving it (Since 9/17/2015). I own a Nest Thermostat from my old house and was wondering if it was possible to switch the Dometic Thermostat for it. I checked the wires and it looks like it should, but...

We are UK owners of a 2011 Elkridge Express E26 and need your help!:confused: When we last used our unit all was fine but we recently moved back in and found the hot water was cold, we turned the gas/electric off and on and tried to re-ignite but no joy. The only thing we did recently was to...

Just noticed that when the furnace is on the fan makes a noticeable change in pitch and the lights in the rv go up and down correspondingly. Is this an indication of a problem with the furnace or the power unit in the rv? We have been at 4 different parks in the last week and it happened at all...

Just got back after three days away & not sure why but the furnace will not light , thank goodness it hasn't been very cold but it's cool enough to be uncomfortable (30 degrees) . Just wondering if any of you seasoned 5er's have any suggestions as to what the problem could be ?

I changed the t-stat thinking that had failed because when I set the t-stat to call for heat, the fan in the a/c unit came on. After getting the digital t-stat installed along with a new control box, the condition still exists. I know that the furnace blower has to come on before the burner...

I ran my furnace for the first time (other than the couple of minutes at the dealer), and noticed the same problem as Urban350's earlier post, burner cycling on high limit. I haven't yet solved that problem (we've been in a bit of a heat wave here for the last couple of weeks), but I'm...

Howdy I have a 2009 26RKS and we just got back from camping. Before we left the campground, I noticed that the refrigerator "auto" light was off when it should not have been. Once I got home I tried to turn on the Dometic refrigerator using electric or gas and nothing happened. I checked all...

My wife and I decided to go ahead with the purchase of a 2012 MPG 183 on Saturday. We did the walk through and everything seemed to be working fine, including the furnace. I was told that to operate the furnace, I just slide the thermostat to the right (with the gas on of course). I got...

Our new rig is currently in for service and has been there for almost 3 weeks. We picked it up the end of February. There is almost no air coming from the rear vent in the living room area - not enough to blow out a match. The local dealership called Heartland and their response was - that's...

but not the stove, it lights just fine. All the sudden neither the furnace will heat or the hot water heater when using propane. The furnace will blow air for a few moments then turn off. I did run out of propane but then filled the tanks but that didnt make a difference. So I am thinking I...

I have an Eagle Ridge 35QSQB, and my furnace doesn't seem to be blowing out of the vents hard, you have to hold your hand right up to the vent in order to feel the air. We stayed in it a couple of weeks ago during some pretty cold weather and it wouldn't keep the trailer warm. I have checked...

We are here in sunny but cold FL and using the furnace a lot more than in the past... of course when we need it the most it quits on us. Initially I'd wake up in the morning to cold (yes we had propane) but if I cycled the thermostat off then on the furnace fired immediately. I should have...

We are in Fl. and should not have to use the furnace, but we have, temps in the 30's last night and tonight. The furnace burner keeps igniting, you can hear that loud like exploding sound several times during a cycle. I know this is not normal, I get very aggravated when I hear that sound cause...

We have a 2010 Bighorn 3580RL. We didn't use the trailer for a few months and then camped at a place where it was cold. When we got setup, I turned the furnace on to heat it up since it was about 30 degrees when we arrived. You could hear the starter click and try to light a fire, but the fan...

The only way to stop the furnace from running is to pull the 20 amp fuse. We have the remote control thermostat put new batteries in to see if that would help, no luck. Even with the fuse pulled the red and green power lights stay on. Any ideas on where to start, it is getting hot in here.

Our furnace in our 3055 has stopped working. We picked up the coach from storage and are now sitting in a State Park in freezing weather, it's dark and we have no heat. :( We had no problems with it previously, it's only been about 6 weeks since we last used it. We turn on the thermostat...

Does the furnace work only with propane? Or can it run just by electricity? Thanks

Okey all you brains out there. Which is more economical to use for heating during the cold nights in Texas and points south in the winter, propane furnace or those little ceramic heaters? Just wondering which is the best way to go. Or, would I do better with a "Big Buddy" propane heater? May...

After poking around in the basement I noticed a puddle of water lying on top of the furnace. Has anyone else had this type of problem with water on the furnace. Almost got my leak fixed on one of the winterizing valves. I wonder why brass fittings are not used when going into brass. Seems...

Well the new circuit boad worked for a few days but here we are yet again NO HEAT! Today I took a compressor and blew out all the gas lines a lot of an oily substance came out so I thought that might be the problem after this I lit the furnace and it ran well for 2 cycles then on the 3rd cycle...

I turned on the furnace for the first time last week to just check it before we go camping this fall. It kicks on and sounds fine, but you can only feel heat, or anything for that matter, coming out of 1 or 2 of the vents. I haven't had time to fool with it yet, and wanted to get some tips...
