furnace

Hey Everyone, I have been struggling with an issue with the RV Comfort Thermostat and the the Suburban furnace. Well, there have been many issues with this furnace, but this one is new and I cant figure it out. I will give some back story here then lead into the current issue. We purchased...

I'm currently in Myrtle Beach and the temp this morning was 40 degrees. I'm on full hookup and the propane furnace started kicking on. I believe that I've read that it will when the temp gets low enough, but I thought the heat pump would handle it till 35*. Is the description I wrote...

We have a 2015 Stealth 5th wheel, model 3514G. There aren't too many of these. Appears the next closest model is the 3512G. Our furnace went out. There is no access for maintenance. No external port and it was built into the wall. Appears the furnace was set in place and then built around. It...

Hi We have a 2018 sandpiper 369kbar. How do I get access to my furnace?

I have a 2021 Georgetown GT5 (floor plan picture included below) and I'm wondering where to find my furnace "unit"? I have restricted airflow in the bedroom and want to trace the duct work back to the actual furnace itself, but I'm not sure where that's located. I know where the intake/output...

Hi all, I have a digital Dometic thermostat that controls heat and AC, and when I try to use the furnace now, it works until it needs to turn itself on again because min temp is reached.* I can hear some relay sounds in the overhead AC strangely enough, and the heater blower starts up, but there...

I have traced that by roof AC is sending the correct signal to have my furnace turn on and I have 12 VDC power going to my zone 1 furnace but still the furnace blower does not come on. Are there and serviceable parts inside the furnace box/unit or do I need to a new furnace? Do the 2 blue wires...

Sooooo you guys had some suggestions on my last furnace not heating post. I whacked it a couple of times with a rubber mallet, opened it up tapped the sail switch. Blower blows but only cold air. Took the front off the furnace to see what I could see (see the pic) didn’t see much. Stove...

I own a 2018 Flagstaff Microlite 25BRDS. I ran out of propane this week, refilled the tanks and reinstalled. The range and oven work fine but can't get the furnace to start. Tried several times to start, each time the fan comes on and runs for several minutes and kicks off. I can hear the...

Our furnace front and rear is not working properly all of a sudden. We have them both set at 76 because for some reason they won't come on if they are set below that. Inside air temp currently 55 (have a thermometer on wall) and the furnaces aren't on. I tried turning them off, waiting a bit...

Hi, Just purchased a 2014 Forest River FR3/25DS. When I operate the furnace, warm air blows from the furnace vents and cool air blows from the AC vents at the same time. When the furnace reaches set temp it does not turn off, keeps putting out heat and the AC continues to blow cool air. When I...

Again, I am still a newby. Taking a trip to the Smoky Mountains this weekend. Temps will be in the 40's at night. I have the standard 9.8 gallon propane tank. How long can I expect my furnace if I set the thermostat at 65 degrees?

AC was working fine but when I changed over to the furnace, the 15 amp fuse blew and the thermostat is out. Even when the main breaker is off when the fuse is replaced it blows immediately. I have a Forest River 2019 Sandpiper 5th wheel

Good evening, I have a 2019 Forester 2501TS. Operating off 12v system, turn power "on" at thermostat, set temperature, heat is automatically selected and furnace works as it should. The last trip our 3rd night we hooked to shore power, turned power "on" set temperature, thermostat automatically...

As the title reads, my furnace took a dump. I set the thermostat to heat and nothing happened. The fan didn't turn on. At first, I thought it was the control board. So, I replaced it and still nothing happens. I think I may not be getting power to the unit. I've replaced the fuses, though...

I have a 2017 forester model 2801qs gts Once a month I run the generator to make sure it is functioning like it should. I run it for about 20 min. Today when I ran the generator I decided to turn on the furnace and check for heat, fan runs but no heat. I shut off the furnace. When I shut off...

Not sure what is going on. I turned the furnace on inside and hear the thermostat click on. Go outside and as I walk by the vent, I feel the hot air so I know it kicked on. I do some more work and come back, walk by the vent and it is blowing cold air. Open the back door and there is nothing...

Hello, I have a 2023 Rockwood 2606ws. It's not as loud inside, but outside it's very noticeable. When the furnace runs, it almost sounds like a jet turbine. Is this normal on newer furnace units? If so, I won't worry about it. Thanks. https://youtu.be/nzQb8O2g-tI

Hello again.....from the newbie! I am getting my Rockwood 2021 A122S winterized and inspected next week. I also want to attach a screen furnace vent cover to keep critters out. I'm not sure where to purchase the cover or how to attach it. Any suggestions? We will be storing inside our garage...

Went on a 4 day camping trip. Set up late Thursday night. Turned the heater on no problem. Once warmed up set heat down to our sleeping temperature. Come morning pushed get up to 70. The fan came on then after about 30seconds it shut off from what I can tell the propane valve did not open and...

Need some help please. We have a 2021 383MB with three AC units and the cadet heater in the bedroom. I am assuming the Cadet is completely manually operated. The Firefly shows a heat pump on the main AC and a furnace on the bedroom AC. Looks like the centre unit is just for extra AC. Winter is...

Hello, I have a 2005 rockwood roo and when I turn the furnace on it ignites and produces heat but we geta propane smell the whole time it is running. When I turn it off it goes away the smell is only when it is running and producing heat. Any help on figuring out what it wrong would be greatly...

I'm having furnace issues on my Sierra FLOK379 but I can't find the access panel to the furnace. I can hear it in the wall by my couch.

Hello all - I've been using (and loving) a 2010 Hawk w/ rollover chouch since purchasing (through this forum) in 2015, and I am looking for guidance on adding a propane furnace. I've reached out to Stan at FWC, who told me that simply adding the current Dometic unit DFSD 12111 would not simply...

The furnace blower starts and shuts off at 30 seconds. Then, it does not try again even though the thermostat is calling for heat. If I shut off the thermostat and restart it, then the furnace does the same 30 second blower run and shuts off again. The gas water heater and all the stovetop...
