My furnace isnt running right now. It is a gas furnace . The name on the front pannel says Duo-therm.?

Question

I live in a small mobile home not sure how old my home is but I would say probably around the late 50's or early 60's. I am having the gas company come out to fix it but not until the first. I joined something with them called an appliance plan where they can come out and fix your furnace free of charge sort of because you pay 10 dollars a month on your bill which isnt bad considering how much repairmen can cost. Meanwhile a neighbor tested the electricity with a tester and found no current in my thermostat so he guesses that may be the problem. When I turn the dial on the thermostat their is no click nothing. I dont have circuit breaker on the wall, only the screw in fuses and they all seem to be okay. I already tried plugging and unplugging my furnace from the wall but it made no difference. All other appliances on that same wall seem to be working. Could you give me some insight as to what the problem could be

Answer 1

Look inside the furnace and see if the pilot light is lit if you haven't already. If it is lit and won't stay lit then you have a bad themocouple and that part can be obtained at a hardware store. If the thermostat is non functional the is is probably the 24 volt transformer located in the furnace unit providing the unit has electricity going to it. Good luck and hope this helps.

Answer 2

when you remove or open the door there is a small box on the left side just below the blower shelf facing out. there is a shallow depression around a hole in cover with a small 1/8" button in the middle. Press this button. it should click. This is the high limit and it will trip for several reasons. covering the registers to thaw pipes restricts the flow to the point that heat builds up in the furnace cavity or the power failed for a brief time so the fan didn't run when the furnace was heating are two very common reasons. often there is a summer and winter switch or two locations where the fan cord plugs in one for winter and one for summer. If you plug the fan into the summer location it should run all the time, by trying this you can determine if there is 110 volts to the furnace. If the reset does not work it is possible that the transformer is bad. There is only 24 volts running to the thermostat.If you check the thermostat voltage by checking between the red and white and the high limit is tripped you will get no reading.Many thermostats do not audibly click. touching the red wire and the white wire from the thermostat in the furnace compartment together should kick in the furnace. others have suggested the pilot, These are just a couple things in addition.

You should not pay for service that you are not getting. I contracted out for our local energy supplier and we had a max of two hours to show up at a no heat call! they appear to be blowing you off!

I agree with both Allen & William. Is the furnace purge fan blowing when you turn the thermostat up? If not after plugging a light into your outlet to prove you have power. Plug furnace back in. Remove themostat from wall. DON'T take thermostat wire loose. Depending on the thermostat, you will see a wire marked W & one marked R, maybe a G wire (Fan) Now touch with a short piece of wire, the W to the R terminal, if your furnace runs, you have a bad themostat. If not, I would be checking the low voltage transformer primary leads and secondary leads with a meter.( Testing for power at the thermostat will not show you if you have power there as it is only one side of the line. D/C voltage) Now, that is a very old furnace and may be unsafe. Better safe than departed.

Answer 4

You are going to end up freezing all your water pipes and having a big insurance claim. The furnace will only keep the room with the thermostat at 58 degrees. If the temperature in that room is higher due to the gas fireplace all other rooms will drop well below 58. Plus, gas fireplaces are not nearly as efficient as furnaces for moving air through the house so unless you want to huddle around the fireplace 24/7, you are going to have to turn up the furnace to make the other rooms liveable. Just use the furnace and set it at 68 and wear a sweater, that is what it is intended for, you will create too many problems just running the gas fireplace.

Answer 5

I ahd the same problem in a travel trailer. The furnaces in them were only made for camping trips, not full time living, so they go bad after years. Check the vent for wasp nests, if it gets clogged, they stop working. Does it come on at all, but blows only cold air? This would be a bad heat exchanger or sail switch. If it does not come on at all, could be the master board or motor. These are easy to remove, and take into a Mobile Home repair place. Look up the model number on the internet, download the owners manual and remove it. usually it is just one gas line, several screws, and the intake and exhaust vent hoses to remove, they usually slide out of a metal box the ducts atttach to. Some older Duo-Therm units need to be replaced with modern ones, like a Suburban furnace, and they can cost up to $1000 if a shop puts them in!! No way around it, though, if it is unsafe. have it tested, and good luck!

Bad thermostat
