Question Replace/remove gas furnace in 05 Dolphin

I replaced the NeverCold refrigerator with a domestic refrigerator in 2020. The new refrigerator sits on top of the gas furnace and that's a space problem - the refrigerator rubs against the ceiling.

In over 10 years of use, we haven't had to use the gas furnace more that 5 times and then for less than 10 to 15 minutes before the room temperature is high enough to make it easy for the HVAC to keep it warm.

I am thinking about removing the furnace altogether but am worried about what the thermostat would do if the furnace wasn't there at the end of the wires.

What does the IVR2 Oracle have to say?

Is there a physically smaller furnace that I could put in place of the 2005 version, perhaps on top?

Thoughts and prayers?

Disconnect the DC + wire from Fuse Panel to the Furnace and wire nut the end then warp it will electrical tape.....Both End...at fuse and at furnace.
Label it for future reference

T-stat will not 'care' unless you try to use HEAT Mode then it will not work

Smaller furnace....smaller in btu rating but majority use same size cabinets etc


Post Brand/Model for more 'specific' info

Thanks Old Biscuit for the sage answer. This will be one of two September projects. I'm going to reconstruct the media shelves to the right of the front TV. Right now its a brier-patch to work on.


I don't mind less BTU rating, perhaps I need to look into an electric element+fan type solution to replace the gas furnace.


Thanks again.
JJ

Hi JJ,
I had my Norcold 4 door totally rebuilt last year ($$$$) because of the issue you are working thru now and mainly because I do not have the skills to do any of the retrofits myself. My Norcold never had a cold problem until it quit so I did not want the hassle of reconstruction. So far so good.

As for the heat solution, because I rarely use the belly heat at night: I have carried a small electric heater for years that has a thermostat and an added timer. It is in the kitchen area and set to come on 15 minutes before I wake up or I turn it on as I am letting the dogs out.

No technical advice from me and not what you were asking but maybe a simpler solution rather than replacing the gas furnace.

Just wanted to say Hello.

Sandi

PS...still have the original TV but may have to convert soon.

Once the board in the furnace was replaced, the heating +HVAC worked?

I see your predicament, but I'd think twice about removing the gas furnace entirely, just for resale value of your coach if nothing else. I use the heat pump most of the time myself, but we've taken a couple of trips in the last year where the temperature got down in the 30s overnight, and then the heat pump is mostly blowing cold air. 10-15 minutes of the gas furnace first thing in the morning makes all the difference. I think heat pumps are a great energy saver (have one in my house too) but I wouldn't buy a rig that relied on one 100% of the time.

Next steps

I just sent a message to the brain trust at rvpsupport@airxcel.com, the company that still makes & sells the HVAC unit and accessories.
I included the pin-out diagram of the connectors to the thermostat and the opening showing the furnace.
I asked 2 questions: 1) is there an electric heater I could substitute and 2) if not, what should I do with the "Gas Heat Out" circuit coming from the furnace to the thermostat?
I'm thinking about putting an electric wall heater above the frig to provide extra heat if needed.
