furnace

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...

I have a 2015(?) Crossroads Sunset Trail Reserve ST26RB TT. My furnace is showing symptoms of a possibly bad/dirty sail switch. My issue is that Crossroads doesn't seem to have designed the location of the furnace for easy access. There is not access panel on the outside of the RV, only the...

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 - need some help with my furnace that is not working. I have a 2019 jayco fifth wheel 29.5 FBHDS and camping this weekend the furnace stopped working the first night. The blower kicks on runs for 15-20 seconds and then never fires and turns off. After researching it sounded like the sail...

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...

Hello All Just came back from a great trip in Michigan. The last night away was rather cool so we put the front furnace on to warm things up. The furnace came on like it should but so did the front A/C unit. Counterproductive to say the least. The same switch on the wall controls both the A/C...

Control panel for furnace/ac has no lights, no power, no way to turn on furnace or ac. Checked fuses, circuits, battery, did power reboot, nothing gets it to work. Any ideas or suggestions? Do I need a new control panel? Thank you.

Our Atwood furnace ignites but goes immediately back out. We’ve replaced the circuit board, valve, and igniter and the code still shows gas restriction in the line. Our RV repair man who is brilliant said that it wasn’t getting enough gas to the igniter to keep it burning. He noticed a place...

Used furnace on our 2022 EPRO 19FD for first time. CO detector went off. Used bathroom exhaust to vent camper. I assume the furnace should be properly vented. Any recommendations on how to correct this? Dealer is hour drive. If nothing else I will have dealer address when I winterize.

Having troubles getting heat. Would not light, fan works, igniter clicks. I blew air into outside both vents outside thinking a bug or web was inside even though both looked very clean. Got the furnace to light. However once unit heats camper and shuts down it will not relight. Ran great during...

My furnace won't seem to turn on all the time, and sometimes when it is running it turns off after half a minute even though it's ice cold inside and thermostat is set to max. Some notes: - 2019 forest river salem 17 rbxl - suburban(?) furnace, - dometic thermostat (white and touch sensitive)...

Furnace works at 7500 ft but only the blower turns on above 8000 ft. Furnace has new sail switch. Have tried severity times but just get the blower. Help?
