Suburban Heater-20' Argosy M.H.

Next on the list is to replace the heater. Before I take it all out, I am hoping someone can tell me how to remove and replace the Suburban heater without taking out the stove and sink on a 20' Argosy, rear bath model. I have a couple of pictures attached to show the set-up. Please tell me that this is an exception, and it is a simple procedure.

I think the stove comes out fairly easy. It should only be a few screws and the LP line. I think you'll find it worth the effort. You'll have much better access to the area. Removing the counter top should not be necessary.

(Disclaimer: I had a shop replace my original Sol-Aire furnace so I did not do this myself. I do have pictures of the process.)

I agree, the stove is a fairly easy item to remove. The top of the stove should lift off and expose the LP line. loosen that up and find the appropriate screws to remove that hold it in. Viola! it lifts right out. I think it took me about 5 minutes to get the stove situated in place, LP attached and 4 screws to hold it in place when I put the new one in my unit.

Your old furnace should remove fairly easy. On the outside of the RV, remove the vents for the furnace. Then come on the inside and remove the access panel. There should be a few screws holding it to the floor/platform, remove them. Assuming you have already removed ducts, LP, and wiring, the old furnace should just pull out.

Are you scrapping your old furnace? If so I have a few parts that I could use.

It looks like this is one of the next major projects. I am currently removing the wallpaper covering from the cabinet doors and replacing with oak veneer. Once that is done, I will probably take on the heater. Thanks for the photos. They really help. I will need to replace the entire furnace. Any usable parts will be available for reuse to those who need them. However, I am replacing the furnace, because the MH was stored by the PO for several years, providing warmth and comfort to several mouse families. While the heater was not working, they found the electronics area in the rear the best place to nest. So, rather than replacing the switches and electronics on a 39 year old furnace...I'm just replacing the whole thing. I doubt that much beyond the chamber and outside housing are going to be any good. Mouse piss really does damage to electrical parts and electric motors.
