furnace

I have an SF-35FQ furnace. When I plug in the fuse it turns on and ignites fine but will not turn off. To turn it off I close the gas valve, wait for it to cool then pull the fuse. After I reconnect the fuse it starts blowing, immediately, and opens the gas and ignites. I have changed the...

We recently purchased an 04 Puma to live in and while the A/ was fine were needing to switch over to heat but the digital thermostat has no heat control options at all. However we have a spot that says "furn" on the fuse panel. Can someone tell me if we even have a furnace and if we do where is...

I have a '14 Rockwood 128S. This is my first RV ever. I have no manuals. The Cool Cat has an oval control panel/thermostat with a choice for 'Furnace'. I don't see another thermostat. I've had the rig for about a year and haven't had need of the furnace so it's not been touched since I got it...

My furnace keeps shutting off will run fine but then just stops the thermostat was replaced. Still shuts off set at 72 but temp will go down to 65 and it still doesn't go on. If I shut it off and turn it back on it will run again but does this all the time. Help

Hey all, first time using this camper in the cold (just bought it used this year), and the furnace either won't ignite or won't stay lit (can't tell which). I have full battery and full gas tank. Thermostat set to auto and set to furnace. Set the temp to high. The furnace fan comes on and I can...

My 2019 Leprechaun 260DS furnace since new has never worked properly at high elevation. We were in San Diego last week no problem. Today we are in Flagstaff, Az. And the furnace will continually cycle. The furnace heat up as normal then it will … flame out…. And will continue this until the...

Hello all, Suburban Sf-30FQ furnace, about 6 years old. Trouble started when it wouldn’t ignite. The fan would turn on, I heard the igniter clicking and no flame. The flame would start, I would feel heat in the exhaust, then the flame would go out. Igniter would start again, flame would start...

2021 A213HW. Got it last month, hooked it up to shore power and tested everything at home before heading out this weekend. No problems. Set it up this weekend in the mountains and could not get the furnace to work. The blower would cut on for 15-30 seconds and then turn off. The heat would...

We have a 2017 travel trailer. When we fire up the Atwood furnace, it will ignite and run for maybe 3 to 5 seconds and then it stops heating and fan only. After the 3 times it will not ignite again, fan only. Any thoughts? Thanks!

I have a 2014 Flagstaff V lite 30 WFKSS trailer. The blower motor on the furnace is not working. I can fix the blower motor if I can gain access to the furnace. The furnace is located under the cabinet to the right of the front door. I can take the vent cover off but it does not give me access...

I installed a cooling only 13.5k BTU Houghton (Rec-Pro) AC unit last summer. This disabled the thermostat on the wall and therefore the furnace. I just installed a Dometic heat only thermostat for the furnace. There are 2 small white wires and 2 small red wires in the roof where the AC unit...

Hello friends, I was wondering what (if any) maintenance should be performed on my Suburban furnace. I usually disassemble and clean the Dometic fridge burner area once a year, and I do the same to the Water Heater. I never touched the furnace, but I’m sure *there is* maintenance/cleaning to...

We have a 28 ft 2015 Prime Time Avenger. We have replaced the circuit board in the furnace compartment 2 times and now realize that rain water is getting into it through the slots in the cover panel causing the board to short out. The slots in the cover panel don't seem to be well oriented for...

Circa 2003 rock wood pop up has a suburban furnace. It's a suburban DD17DSI. It rarely will work, and when it does - It works well. But 90% of the time - Fan turns on when Thermostat triggers... and then there's no clicking for the igniter. It'll just keep attempting over and over again. I...

Hello, recently my fan has started running every time I turn on my furnace. I’m talking about the fan in the ceiling (a/c fan). I assume it’s a fuse issue but I don’t have a fuse schema. Anyone had this issue before and know how to remedy?

Has anyone sealed off the floor opening where the duct work goes through the floor into the underbelly? On our 2016 Forest River Salem Hemisphere Lite M-299RE the furnace is under the stove and as you can see in the photo the ducts go down through a large hole in the floor. Last weekend we had...
