SOURCE: pilot light will not stay lit

The flame must satisfy the thermocouple. Then the thermocouple must satisfy the valve. If you have a great flame on the thermocouple, it is possible that you have a bad gas valve, if no other saftey switches has you shut down to not allow the valve to open.

SOURCE: The furnace burners won't stay lit

Could be a couple things. First and easiest is to check your intake combustion air supply. If it is blocked by anything or just not enough flow, it will put out the flame. Next would be the flame sensor, usually a temperature probe near the flame front. If it's not reading an increase in temp within a pre-programmed time, it will kill the flame. It can be checked with a multimeter.

Good luck!

SOURCE: Rheem gas furnace pilot lights, but no burners or fan

If the burners do not fully ignite, the sensor will shut the furnace down. The lack of sufficient burner flame is a gas valve or gas pressure problem within the valve.
Replacing the gas valve with the original one may get you going. I surely suggest a professional service company for safety reasons and a thorough inspection. A 20 year old furnace is past it's normal life span.

SOURCE: cozy furnace

The pilot orifice could be dirty causing the pilot flame to be too small. Unscrew the pilot tube at the pilot assembly. The orifice is inside. Remove the orifice and blow it out with compressed air only. Reassemble and see if that fixes the problem. If the pilot flame is set too low, sometimes opening a door will cause a draft to blow out the pilot. If the thermocouple is good and the pilot flame is set properly, the control valve may be bad.

SOURCE: pilot light wont stay lit.want to clean the orifice

You shut off the gas.
Shut off the power.
Remove the gas valve and burner assembly.
After cleaning and reassembly you must purge the system and use a gas leak detecting soap to verify no leaks before turning on the power.

Pilot on my gas furnace won't stay lit


Try cleaning the thermocouple tip if you can see ashes or any buildup on it. If you know the wind isn't blowing it out (had mine blow out from high winds before) then I would change the thermocouple before anything else.

Janitrol GUPS075-3 Furnace burners will not stay lit


The first thing I would do is make sure the flame sensor is clean, this is a metal rod immersed in the burner flame on the opposite side of the igniter. If too much oxidation builds up on it, it will not allow the burner to stay lit. To clean, just turn off furnace and remove flame sensor and clean with steel wool and then reinstall. If this does not solve the problem there may be a problem with the gas valve.

When I tried to light my furnace, the electrical wires from the thermostat don't spark all the time, therefore my furnace won't stay lighted. What can I do to fix this?


Is this an older furnace where you have a pilot light? Are you saying the pilot light will not stay lit? If thats the case then likely you need a new thermal couple. That is what the pilot light keeps hot while it stays lit. It is a safety device that is there so your furnace will not come on if there is no pilot light present. Very common. Hardware store item. Need Furnace's make and model #'s.
If this is an electronically controlled furnace, you will need a service call.

Pilot won't stay lit on furnace


Is that pilot automatic? If so then a quick easy fix for this is to located the sensor and replace it or clean it up with sand paper. After ignition the control is looking for verification of ignition from that sensor. How to videos

Pilot light will not stay lit


Will it stay lit for a while? If so light the pilot light, Turn on the blower fan, and watch the pilot light. Look for any air that's blowing the pilot light around. if the pilot lite is moving around then you could have a bad heat exchanger. If so you should get a carbonmonixide detector and have your furnace inspected for this. One thing to check also is make sure the thermocouple is at least 1/4 inch into the flame.
