homelesshartshorns Posted February 21, 2020 Report Share Posted February 21, 2020 I have a 2000 Suncruser with basement air that I love. I have a gas funerance that I hate. Problem is I don't want the gas funerance to come on at all at anytime. How can I simply cut it out of the system?

Dutch_12078 Posted February 21, 2020 Report Share Posted February 21, 2020 If the furnace is on a dedicated fuse, unplug it. If not, there's a plug that connects to the ignition module in the furnace. Unplug it...

Kirk W Posted February 21, 2020 Report Share Posted February 21, 2020 Remove the fuse that supplies power to the furnace? If that isn't practical you could also lift the 12V lead from the terminal block where it connects, usually found inside of the rear access panel for the furnace.

homelesshartshorns Posted February 21, 2020 Author Report Share Posted February 21, 2020 If I take the wire off at the Furnace will it affect how the Thermostat works or mess with the gas? I understand the concept wonder if anyone has done this for themselves?

Dutch_12078 Posted February 21, 2020 Report Share Posted February 21, 2020 All that will happen is if the thermostat calls for heat the furnace will not run.

Ray,IN Posted February 21, 2020 Report Share Posted February 21, 2020 (edited) Since the LP furnace and Coleman-Mach heat pump operation are tied together via the thermostat; when below a certain temperature the thermostat turn on both units until the inside temperature and outside temperature reach a specified range. When the basement unit begins to freeze up the 'stat turns it off until the outside temperature rises. That's my best shot at explaining how the combined system functions. For complete information and wiring diagrams see the service manual: http://www.rvcomfort.com/pdf_documents/1976323_copy8.pdf Edited February 21, 2020 by Ray,IN Quote 2000 Winnebago Ultimate Freedom USQ40JD, ISC 8.3 Cummins 350, Spartan MM Chassis.

GlennWest Posted February 21, 2020 Report Share Posted February 21, 2020 I would think just cut the thermostat wires and wire nut seperate and tape. All the gas furance does is make a connection at theremostat.

Dutch_12078 Posted February 21, 2020 Report Share Posted February 21, 2020 Unplugging the ignitor board does the job and is easily restored if needed or when selling the RV.

homelesshartshorns Posted February 21, 2020 Author Report Share Posted February 21, 2020 Ok I unplugged a 5 or 6 wire plug in the Propane Furnace area. I now only hear the Thermostat click when Propane Furnace should come on, but it doesn't come on! The Heat Pump still works as it always has. It still acts as if the Propane is still there. Only working in the 1 or 2 degree range. But now if I forget to leave it on after shutting down the Generator. It will not turn on the Propane Heater with out me being aware of it. Thanks again for suggestions.

Dutch_12078 Posted February 22, 2020 Report Share Posted February 22, 2020 Great! And it will be easy to reverse when/if needed...
