SOURCE: COLEMAN FURNACE BURNER NOT LIGHTING

There is a thermocouple "wire" that is supposed to be touching the pilot flame.
The thermocouple senses a flame (hot) and allows the heater to operate. If the thermocouple does not sense that the pilot is on, then it will not allow the furnace to operate.
Bend the thermocouple wire (or the pilot tube) so that the pilot flame is touchingg the thermocouple.

That shouls work now.

The air from the fan should not be blowing through the same cxavity that the pilot is in.
If it is, then you may have a leaking furnace whereby carbon monoxide may be seeping into your living quarters.
If the fix above works and the pilot stays on after the heater starts, then there is probably no leak.

Let us know the results ... post a comment or "RATE" this or another expert's solution.

SOURCE: I have a wall furnace whose fan short cycles on

Could the fan motor be heating up and shutting down on thermal overload? How long of a duration does it stay off before it starts again? Typically there is a bi-metal switch that rests on the heat exchanger and starts and stops the fan motor. If it is bad or not resting against the exchanger it will not operate as it should. Check the location of the switch. If it is touching but still cycling, test your switch with a multimeter set on Ohms. Let the heater run, jump the two wires you pulled off the switch (they are 120 volts so be careful) and watch your multimeter to see when the switch opens and closes. If it cycles as it has been, you have a bad motor. If the switch closes as the heat exchanger gets hot and stays hot as long as the heater is running, the switch is good.

SOURCE: I have Wiiliams direct vent wall furnace. I smell

Dear Alex191: I am shocked and amazed that the Williams heater company is STILL knowingly and willingly selling faulty direct vent gas heaters. My problems took place in 1988! I bought a 30,000 BTU Williams DIRECT VENT from The Home Depot. I took the time to remove window sashes and run gas line to the Williams heater that I had placed in the window aperture. I was glad to finally have heat and be able to heat the area of the house where I stayed. Then I began to smell gas when the Williams was OFF. I traced it to the area where the pilot light gas tubing entered the combustion chamber. I removed the Williams unit and replaced it with an identical make and model and the SAME THING HAPPENED!!! I sat on my bed and almost cried. I had the gas company come out and they labled the problem as a "fuzz leak". The warranty repairman came out and had no idea what to do. Tightening the retaining nut did nothing. I called Williams and even back then they said that they were aware of the problem. They called me back and wanted to send me a part and asked me, "Can you work on it?" I returned the Williams and bought a Perfection-Schwank CONSOL heater that burns the air in the room and vents horizontally to a 4 inch vertical gas vent and was very satisfied with it. When they went out of business I bought an "Empire" brand gas heater. I don't know if I'll ever buy another direct vent heater from anyone. I will be glad to write an affidavit should you decide to suit the Williams company.

The heater turns on, but does not ignite. The fan runs for about 5-7 seconds then shuts off. I am assuming the heater needs a good cleaning?

My furnace keeps making an explosion when it ignites


The amount of gas buildup is too great. Make sure the burner ports are clear right next to the pilot light area. - run a small wire into the holes to make sure they are clear then make sure the pilot light is burning into the area next to the burner. A bit of whoosh is to be expected but if it becomes too great it will blow the pilot light out. Sears wall furnaces are prone to this the burners have to be kept clean

Goodman furnace gmh95090cxac wont stay lit keeps clicking will lite then clicks back off what would be the problem


Hello, if the burners light but do not stay on for more than 10 seconds, I would clean the flame sensor. The flame sensor is a metal rod that is on the opposite side of the Igniter, sometimes it gets coated by oxidation and does not sense the burner flame and shuts the Furnace down. To clean to kill power to tje furnace, remove flame sensor and clean with a steel wool, then reinstall and start Furnce back up. If this does not work then most likely the Igniter is too weak to ignite the gas and will have ro be replaced.

Furnace filter is black and sooty wall seem to be sooty


   By sealed unit you mean that the burner air comes from outside of the house?      You have checked the heat exchanger for cracks by removing the burners and looking with a mirror and flashlight, correct, or had a service tech so?
The furnace burners have enough air and are burning clean (blue) with just a tip of orange at the end? You bought the house new and the fireplace has never been used?  If it has been used to clean smoke for the house for whatwever reason I woudl start by havign the ducts cleaned.   Another possibility I have seen is insolation inside of ductwork breaking down.

Gas furnace wont stay lit


sounds like the thermocouple that senses when the burner ignites is faulty. when the burner is first lit it looks for a signal from the thermocouple telling it that it has ignition. i have had some luck removing the part (furnace off) and sanding it clean. this is located in front of one of the burners..Good luck

Williams wall furnace no longer adequately heats home


A couple thoughts. On some of the wall furnace gas valves there's a knob that you can set for low fire or high fire. If your valve has this make sure it is in the high fire setting. Is the wall furnace controlled by a wall thermostat or a knob on the heater? With the thermostat turned all the way up like to 90, does the burner and fan continue to run or is the burner short cycling. Is the fan clean and running up to speed. Some of the Williams wall furnace had a two speed fan motor so when the fan came on at first it would run on low speed. As the heat exchanger got hotter the internal fan switch would switch it to high speed. Outside of that you would need a monometer to check the manifold gas pressure.
