No heat in bedroom

Well not much heat coming out of the bedroom register. Down in the living room it's blasting hot air out. I have no leaks in the duct that is visible in the cargo area. Is their away to check the rest of the duct without removing the coroblast on the bottom? Maybe under the stairs? It's the model in my signature.

You shouldn't find anything by going underneath. What you need to do is take the wall out of the basement. Not a big deal just some screws and then you should be able to get in there and see what is happening with the duct work. Usually, it's coming off the connection to the furnace itself.

I just took the grate off the furnace, it's right under the refrigerator. I turned on the heater. Their was so much hot air blowing out of the metal furnace enclosure. Their are 6 "Knockouts" for additional ducts? Only one out of the six has a duct connected to it, it's a 2" flex hose that appears to go down in the under belly. 3 of the other knock outs were loose with a lot of hot air blowing out right under the fridge. I got them all tight and sealed them with Flex Seal. Then the furnace pushes the heat to the door that I removed, it appears that when the air hits the door it's forced down into a duct that leads under the floor to the registers. When I reinstalled the door and turned the furnace on hot air was blowing out the door seams, so I sealed all the way around the door. Now their are no leaks around the furnace. It made the 2 registers down stairs blow even harder then before. The bedroom heat was increased slightly but not even close to the down stairs. Before I can start removing wall in the basement, I have to remove all our CRAP we have in their.

I didn't have any heat to my bedroom either until I reconnected the heat duct that supplies the bedroom to the furnace.

I have just the opposite, most of the heat goes upstairs and cooks you out of there. Can I divert without to much trouble, heat to downstairs instead of the bedroom?

I have the same unit and my 2 hardest blowing are the bedroom and near back window. I think because they are at the end of the line and the pressure builds up there. I would bet that the duct came off

Mel, it would be my guess that you have several two inch ducts leading from the furnace to the main duct in the floor off OR have several that have not been hooked up at all and will possibly find them laying on the floor when you remove that back wall in the basement. I took mine off several months ago and found one of the ducts had come loose from the furnace and one was misdirected. The misdirected one was the duct that just goes along the floor and was suppose to go down between the black tank and gray tank to put some heat into the belly. I redirected it into the belly and also took a PVC "Y" and cut the duct going to the bathroom and connected one side of the Y to the balance of the bathroom duct and added another 2" duct to the other end of the Y and directed it and secured it to the area behind the convenient center to put some heat there to keep the pipes from possibly freezing IF the temps drop to much. This also throws heat into the void area behind the basement wall and also into the belly for the water lines. SO FAR it has worked for us but if we do get warnings of any freezing temps overnight we always make sure there is adequate water in the fresh water tank, unhook and coil the fresh water hose and run off the tank for that night or more. We normally do not get into really cold temps while in AZ but we have had a few nights that the water line had froze because we did not unhook it. Learned from those experiences for sure. Just got lucky and the total water lines did not freeze.

We had the same issue, the duct line next to the basement wall where the wall pushed up against it was torn open, repaired duct and had plenty of heat/air flow.

we have a 2007 3000RK and the number of mis-aligned/ disconnected hoses coming off the heater were enough to make one wonder if the person who connects them was out for the day our rig went down the assembly line and they just completed it without that person. As others have said, not hard to get to and easier if you bring the thermal tape/flex seal with you when you climb up on the basement than having to look, see the issues and come back out for the tape.....you WILL need some.

Bedroom heat

We had a similar problem. Had to remove basement walls to access, but discovered that the aluminum duct hose had come loose from the ductwork. I fabricated a plenum, out of aluminum sheet metal, then secured it with some rigid metal straps anchored to the the aluminum floor joists. Labor intensive and difficult to access, but now it's better built and permanent. Given the constant bouncing you get while traveling, the system was designed and built to fail. It's not just Montana's either, there are plenty other companies that build with speed and not integrity.

I'm looking at this thread because we're seeing lower flow and lower temperatures to the den floor register and the front bedroom wall register than we see at the living room floor register and the bathroom floor register. I'm not excited to see the part about torn duct hose....but it may also be our reality. Is the hose any different in the 2018 high country models? We have a 2018 362RD (delivered to dealership winter/spring 2018).

Also, to tag onto the above post, should we remove the underbelly to access the ducting to the back den floor register? Is there anything we should do first - even if it's just a short-term solution? Back den is running in the low 60's while the main living area is 73. Thanks in advance.
