Home Duo-Therm Furnace Bobby Woody 10-31-02  
I have a Duo-Therm furnace in a mobile home and I am trying to change it over to LP from Natural Gas. The cover has some instructions on it but I need a schematic of the furnace so I can locate the burner orifice. The model # is 750-3R-4. Any help would be greatly appreciated.

I have a duo therm model # 1489-7
every thing on the heater works besides the blower motor located on the right rear of the unit. There are instructions on how to oil the motor but it seems to be seized. Any one have any ideas or do you know how to get another blower motor..

thanx matt

Re: Home Duo-Therm Furnace Frank Brandenburg 12-2-02  
We have a Duo Therm furnace that has recently stopped working. We live in a mobile home. The Model # is 74503-8. The serial # is 01459.
It has an input rating of 58000.

Drill size oraface is 43 for LP Gas. We heat with propane. We're looking for the pilot burner for this furnace. I believe a man at the hardware store called it the pilot oraface. Any help will be greatly appreciated, as we can't find this part anywhere.
Re: Home Duo-Therm Furnace RV Wizard 11-2-02  
The burner orfice is located after the gas valve and just before the burner. It will have to be removed from the unit and replaced with orfice rated for the LP BTU's stated on the nameplate.

Re: Home Duo-Therm Furnace Linda 2-20-07  
About 6 months ago, I removed the sequencer from my electic furnace (Duo-Therm model #301050-001) to have it replaced. I have since forgotten which wires went where. I was told that although the new sequencer is slightly different than the old one, it should work. In searching the web, I come across very little information on Duo-Therm Furnaces. Is there a wiring diagram that I can get for my model??

Re: Home Duo-Therm Furnace andrew 4-8-09  
Model 72503-6 how old is it
Home Duo-Therm Gas Furnace Kathy 6-25-09  
We have a Duo Therm space heater (or furnace?) that runs on natural gas. It's about 3'H x 2'W x 2'D and is used inside a home. It's developed a leak around the control knob that's used to light the pilot.

The model is 1489-2. Serial # is 228. And if it matters, Type Control = A.

Does anyone know: how old this unit is? Is it possible to repair the knob or replace the entire contraption that the knob is attached to?

Or... is there a website that has all that info? I've looked all over and can't find this model.

Re: Home Duo-Therm Furnace - Blower motor needed for model 77201-001 Catherine Mitchell 3-6-09  
I am looking for a blower motor for an older Duro Therm Furnace. The model number is 77201-001. Can anyone help me find one for the best price. I am shallow in funds, so I am looking for the best deal possible. The bearings went out of my old one here. And the brackets that hold it on is bent. who ever had this trailer before me has twisted the brackets and put the a blow motor on that is not for this furnace. It does not even fit right inside. It works for now but only will last for so long.

Re: RV Duo-Therm Furnace Bern LaLone 12-29-02  
I have a Duo Therm, Model 90030-612, furnace in a Taurus RV trailer, year unknown. It was working fine but suddenly quit. I thought at first the pilot had gone out but it apparently has no pilot, as there are no instructions for lighting it. Can anyone give me the test points to check the thing out? Or tell me where I can get an owner's manual or repair manual? Or who works on these things? West Virginia eastern panhandle area.

Re: RV Duo-Therm Furnace Had 7-27-03  
We can service your unit (Duo-Therm 900 series) or supply an installation and/or owner's manual for a nominal charge. If it suddenly quit, the control module (igniter) board is probably burned out. They run about $ 122.

Re: Mobilehome Duo-Therm Furnace Teresa 9-21-17  
I have a 1974 Titan Trailer, and a Duo Therm furnace...electric, it works fine except that the coils come on for no particular reason and shut down when they get too hot because the blower is not coming on, the blower works fine with the coils when the thermostat turns it on. Other wise they just come on and go off for no reason. Maybe a relay switch problem I have already remover one of the four coil plates...what do I do? Where are these parts?...........Thank you
