Hello to all. I have a Duo-therm furnace, a early 80's model, that the pilot will not light. Everything has been cleaned. When you hold the pilot primer down to light, it will go out instantly, and if you hold it in, it will just burn for a few seconds, and then goes out. Any thoughts?
I have an 84 travel trailer with a Duo-therm heater in it. The striker will light the gas but after about 10 seconds the flame goes out. Have had problems when the striker will not even strike. Any thoughts
Duo therm Mod.90025-823 Ser.837289 On a long weekend the furnace worked fine for 2 days and then the last night the blower would kick on but the burner would not ignite. Plenty of battery but no ignition. Propane seems good as stove and frig work. What voltage is required to fire the gas valve and igniter. When the fan runs I notice a voltage drop. Have no manual for the furnace so any help would be appreciated.
1980 Nomad Duo-Therm furnace, pilot lights and continues to stay lit so the thermo-coupler has to be good. When the thermostat is turner up for heat demand, the burner fails to egnite before the fan kicks on and blows out the pilot.
We are looking for a furnace burner for a Duo Therm furnace, Model #65017-1
This furnace is in a 1975 Aristocrat travel trailer. The part number is possibly #92612. New or used would be fine, if you can help us find one or direct us to someone who can.
My Duo-therm furnace model 65930-046 works well, but the blower is very noisy. I would like to oil the motor, or replace it if that doesn't work. Is a repair manual for this available? Can the motor be oiled without removing the whole furnace?
Duotherm Model#78007-001, Serial#L78 640. in 70'X 15' House Trailer. The problem is when I only have Pilot Light on the pilot light is about 8" high It is excessive gas burning so I am guessing gas is bypassing the valve Which is a UNITROL Gas Valve which I cannot find anywheres.Nor would I know if this is the proper Valve?. any DUOTHERM OWNERS that is knowledgeable please assist.5194452424 Thank you

I have a Nomad 5th wheel trailer w/ a Duo Therm propane Furnace that will not light, it has been sitting for prox 6 years. It did light when first tried but the flame was not right, black soot out the exhaust vent. We took off inspection window and blew air in the combustion box to clean out spider webs.Now solenoid will not stay open it just clicks, Could it be bad thermocouple or gas valve. Model #

I have a 1981 tent trailer with a Duo-Therm 66100 series furnace. The pilat lights just fine and the thermostat works good. When I turn the heater on, after about 20 seconds the fan comes on but the burner will not lite. Both batteries fully charged. Any suggestions? I could really use the help. Thank you!! email me at email@example.com
I have an 84 camper with a Duotherm furnace that wont light.When i turn it on,the fan comes on but the burner doesnt ignight.This does not have a pilot,at least I know Ive never had to light one to get heat. I have had a little problem with it not heating up in the past,but usually all I had to do was turn thermostat off and on again and it would work.Any ideas anyone?
I Have a Duo-therm 90130-001 I cant seem to get it to light. I pulled off the front cover so i could check through the site glass. When i turn the thermostat up after a few seconds the blower starts then i hear a click i am assuming is the pilot gas selonoid opening but i dont see anything light and i can smell gas a little. I hear a second click can smell gas a little and still no light then i hear a third click and then the blowers just keep running but no more clicking or smells.
i THink what is happening is the gas selonoid is opening but the pilot is not igniting.. so it switches off blows for a few seconds opens again.. pilot fails then it just clicks off. How can i test my pilot to see if it is getting power? Where should i check with my meter? should i just check it at the terminals where it connects to the ignitor assembly and what should i see there for current??
I have a Duro-Therm Model 65810-002. I just bought this Midas camper the furnace had not been used in some time.I have cleaned the furnace, and had it working now when I release the pilot primer the pliot goes out. I had it to stay on once and light the furnace but about 5 minutes later the valve made a clicking sound and eveything shut off. I tried to light the pilot again but goes out when primer released. Please Help
Duo Therm furnace won't turn off, I have to do a complete shut down to turn it off. It uses a 12Volt Thermostat with a electronic ignition. I tried to replace the thermostat with a comman 24V and I get the same problem.
The operative word here is thermocouple is believed to be ok. There is a tool to check the thermocouple available at most premium rv repair service centers. Most will test it for you free and then you will be sure. However since it is an inexpensive part, after two years of no use itís probably a good idea to change it.
If the thermocouple is changed or tested as good then the only thing left that governs the function of the pilot light is the gas valve.
The thermocouple sends a very small electrical signal in the area of.01 milliamps to the gas valve when heated telling the gas valve that it is lit.
A dirty furnace is likely to burn inefficiently or a bad air mixture may indeed cause a flame out on occasion but neither will affect the function of the pilot assembly.
-IF- you are getting a good strong pilot and the flame indeed touches the thermocouple it is most likely one of two things. The thermocouple or the gas valve. If it has been sitting for a long period in a cold climate the gas valve may have gone bad, thus not interpreting the signal from the thermocouple.
If your 100% sure the thermocouple is good replace the gas valve. If you are not experienced in this type of repair and do not own a manometer I highly recommend taking it too a professional as gas leaks can be very dangerous.
If I can be of any further help to you please feel free to email me at firstname.lastname@example.org
Furnace lights but doesn't burn right at the pilot and won't stay lit. thermocoupler is believed to be ok because once warm it will light with out holding pilot button down but won't stay lit. It almost seems to me that it is just dirty inside from two years of no use or it is an air fuel mix problem. any suggestions?
So does this furnace have a Pilot Light, then it flares into the heating flame when demanded by the thermostat?
If so, it needs some kind of Flame Sensor over the pilot to be sure it's burning. If not, shuts the gas off. There's probably a little time delay to allow the pilot flame to heat the sensor. So... if you light the pilot, and the sensor doesn't signal that it senses heat from it, the gas'll be shut off. Sensor could be mechanical or an electric thermocouple.
Take a look in www.bryantrv.com and the Service Documents, maybe you can find a useful manual or troubleshooting page.

I have a 1982 camper trailer with a Duo Therm gas furnace. Model # 65925-056. Pilot lights and stays lit. Gas valve in open position. When I kick the thermostat on, fan comes on immediately, I thought there was a time delay to let the chamber get hot. Burner never ignites.
My Duo Therm furnace (1982) lights but there is a distinct odor of unburned propane. It sat for about a year before I bought it. The manual says that the combustion chamber should be cleaned yearly, but it doesn't tell you how to access the chamber. I am concerned that the burner may have a problem or the mixture may not be right. I am sure it has not been cleaned in over a year. Anyone have an idea about where I should begin to address this problem?
I have a duo-therm furnace that will not ignite it is model 90020-b has a electric pilot ignition, fan comes on but will not fire- ignition couple combination is over 185.00 any thoughts before i start throwing parts at it?
Anyone have any idea where I can find parts for my Duo Therm glen aire furnace model# 16HU? It's in a 1969 Coachman travel trailer. The poilet will light but no matter how long you wait as soon as you let off the button it goes out.
I have a 77 Pace Arrow. I light the pilot with the igniter. No matter how long I hold the pilot down it still goes out when I lift my finger. I had a problem with the water heater also but after replacing the thermocouple & cleaning the orifice it stays lit until the wind comes thru the vent in the door.
I have a 1984 motor home with a 900 Series direct spark ignition Duo Therm furnace. Model # 90030-711A. When I set the thermostat higher, the fan starts within several seconds, but that is all. No heat. I've tried turning off the gas for 5 or 10 minutes and then going through the same process over & over for several hours, thinking that perhaps it might take the gas a while to get through that particular pipe since it hasn't worked for more than the 2 years we've it. All other propane appliances work. Any suggestions would be greatly appreciated. Thanks, Bob.
I have an 85 pacearrow w/dur-therm heater u can turn on thermostat fan comes on igniter starts sparking but gas valve will not open u can put a hot wire to one side of gas valve and it opens this was all done with gas line disconected and blowing through valve what is safe solution thanks for all imput
My Suburban furnace is blowing the fuse. My husband said that the fan was blowing hot air then there was a sqeaking grinding noise then stopped working. We figured it blew the fuses. Are these hard to take appart?
I have a 89 Glendale 29' travel trailer with duo-therm furnace thermostat. Air conditioning isn't part of the thermostat. Electric ignition on furnace. I start the furnace, all runs well.. for about a half a day..then it won't come back on. I suspect the thermostat is fault, as I opened it a piece fell. Since this thermostat controls just the furnace with an off at one end and tempature setting scale, what other type of thermostat can I use to replace this one.. its cold in here.
My wife and I just acquired a 1976 Dodge R.V. and it has a duo therm gas furnace in it. It has been working for the past 3 weeks, but we moved the R.V. and got parked for the night and I lit the pilot light as I have always done. and it ran great all night long, but this morning it came on again when it dropped temp in the unit and the fan came on, but the burner never came on to give it warm air. The pilot light stays on and never went out. I shut the unit off and ran throught the lighting sequence but no luck. The temp outside is 32 deg. Any thoughts?
I have a 1979 Wilderness Camper. The pilot light will light. The heater will heat thru one cycle, after the burner goes out and the fan quits blowing, the pilot light will go out everytime. I have already replaced the Thermo couple and no change at all. I've cleaned everything. This is a duo therm heater. Please help!
PEASE HELP, I have a 1981 starcraft pop up. The DUO-THERM 66100 propane furnace pilot light will light, but the burner wont light. The fan works and the thermostat works but the burner wont light at all. Please email me: email@example.com
Considering the date I would assume that someone has given you the info you needed but just in case. I rebuilt or replaced much of the gas and electric in our 78 Nomad. The furnace being one of those. I had to replace the gas regulator which is not all that different from the gas regulator on the house water heater. The big difference this the enclose space. I had to figure out how to get tools into the small space to uncouple the gas pipes and electric wire. It can be done, I did it and it world great. So if you haven't already, have fun.
I have an '85 Citation Motor Home which has a Duo Therm furnace which does not work.
It will light temporarily, but goes out quickly. It does not stay lit. Can anyone give some help?
Dealer told me I need a new one????
I have a 1984 Duo Therm Model 65940-067
Which has a fair working electric igniter. However, the gas valve will only allow gas into the chamber sporadically. Lights goes out lights and goes out and with each lighting the gas valve clicks.
Igniter quits sparking within a second after the fire goes out and or relights the gas if within the second. Bad gas valve?
I have a 1976 camp trailer with a Duo- therm furnace model#65917-001 that I just bought and I can get the pilot light lit with a match and as soon as I release the pilot light to turn it on it blows out and wont let me get it to the on position. Any clues on what to do? I've tried holding the pilot light for about half a minute and still nothing. It hasn't been used in a few years so hopefully someone can help. Thanks!!!

I have an old moble home im fix'n up has the same problem as you described burner stays on for about 5 min. then flames go out. i have changed the thermocoupler but the problem still exist. any i ideas?
WARNING....PLAYING WITH GAS FURNANCES CAN KILL YOU OR LOVED ONES....
That being said...sequence as follows: tstat closed, energizes the fan relay, closes sail switch, alowing ignition sequence. There are also high temp overrun switches in this circut....placement varies by model but interuppts the gas igntion/burn operation only(newer models....some older units did kill the motor as well). This is a basic operations scenario that applies to all gas furnaces. Dennis
I turn the thermostat control from the off position to furnace and the blower motor starts up and runs for 30 seconds or so and it then shuts down and thus no heat. This is a RV furnace operating on 12 volt, I have not tried 110 volt yet, furnace is 3 years old.
I have an 1982 fifthwheel. In it is a Duo Therm furnace. When the furnace kicks on, it just blows cold air. I have plenty of propane. The hot water heater is working and so is the stove. Could anyone please help. My model number is 62565925-064.
I have a 1972 cabover scamper with a Duo-Therm Furnace. When I turn up the termostat the fan starts running but the furnace won't ignite. The pilot stays lit. Thinking it's the Thermocouple. Will a universal thermocouple kit work? Also, the 12v wiring will not run the camper. Could the white wires be positive and the black be negative? Any thoughts.
When you adjust the thermostat to the desired temperature, the fan comes on but does not ignite. It has been blown out with an air hose which did not solve the problem. Any help or suggestions would be appreciated.
My Duo-therm furnace won't ignite now for 3 years and I cannot get the hot water heater to work eighter.
What can I do ? I have no 12v batteries up front but I am pluged into the elecrical line with a 35am breaker can I get some information. Cand I do this repair my self.
I am having a similar issue. I have replaced the thermostat and it still is not workinig. Mine will run through a cycle, get to temp and shut down. Then it will never kick back on unless I shut it off and back on. Did you ever get yours fixed? What was this issue? Thanks Dennis
Mike - Before you buy anything measure the : Length
of the furnace now. Also measure where & what size the hot air vents are on the old furnace and draw an accurate sketch for a referance to use when considering a replacement model. Before you remove your old unit measure how much "Extra" clearance you have in length,width & height in inches incase the replacement is larger than the one you have now. The lenght between the end of you unit and the outside wall is the critical measurement ! I bought a used Duo Therm furnace & found out it was to long & now I have to re-sell it & find something smaller. Make sure you are buying exactly what you have now: 12 volt only or 12 volt/110 volt (Combination) or 110 volt only........make sure exactly what you have now and note this on you diagram & ask questions before you buy !
If you have any questions email me, Denny
