My Kenmore 60 Gas Furnace Is Pilot Light Is Shutting Off And When It Comes Back On Its Popping And Blowing Out Flames...Need Help


pilot light will shutoff for few diff reason. 1) thermocouple is too weak. needs to be 20-30 dc millivolts to keep pilot on.
2) negative downdraft is blowing pilot out. 3) continuity in gas valve is fluctuation, causing the valve to close and therefor shutoff the pilot

Pilot light goes out when heater shuts down


Check the position of the thermocouple and if there is one make sure it is very close to the pilot flame Usually when a pilot light will not stay lit, it is an indication that the thermocouple is bad. Replace it.

When I light the pilot light, the heater comes on, but when it reaches a certain temperature and turns off, the pilot light goes out. Please explain very simply, I am not mechanical.


Hello,
It could be a number of problems, so let's start with the easiest! When you light the pilot, is the pilot flame a strong blue color or a lazy yellow color? If it's yellow, it may not be heating the thermocouple sufficiently to keep it lit after the burners reaches temperature, so it shuts off with the burner. The solution is to clean the dirty pilot orifice using a can of compressed air with the straw attached (the kind you use to clean computer keyboards) With the heater pilot turned off, blow air down the flange where the pilot flame burns. If it has an air hole on the side of the pilot assembly, blow air through that too. Then relight it and if you have a blue pilot flame, see if that solves your problem and stays lit through the entire cycle. If not, go to the next problem:

You may have a dirty flame sensor bar. if your heater is so equipped, there is an small "L" shaped bar that protrudes near the end of one burner and senses the burner flame. carefully clean it using a small piece of sandpaper, being careful not to put too much pressure on it which might break the porcelain piece on the other end. Then wipe it clean with a dry cloth or paper towel and try lighting it again and see what happens. If that doesn't fix it, then try this:

It is also possible you have a defective thermocouple. Typically when they go bad, they won't stay lit at all, but sometimes they do light and go out later. Solution: Replace the thermocouple. It is the skinny metal bar that the pilot flame is heating. It is screwed into the gas control on the other end. Make sure it is cooled down before pulling it out of the pilot assembly. Don't worry, it doesn't have gas coming out of it and there is no electricity connected to it. Remove it and measure it and take it with you to the nearest hardware store or do-it-yourself center and they will match one up for you.

Other possible problems could be a strong draft blowing in the vent and blowing out your pilot, so make sure you have a vent cap outside. Or it could also be a blocked outside vent that is causing it to shut down, so check for blockage via a bird nest, dead bird, wasp nest, etc. Hope these help!

Let me know if you need more info or if one of these works for you! Douglas

Pilot light wont stay on. How do you adjust pilot flame? Pilot flame doesn't reach temperature sensor.


then the pilot is blocked needs cleaning out or try blowing it out with air , or undone pilot and remove pilot injector and clean it .

My patio mushroom heater lights up ok but keeps going out by itself after about 5 to 10 minutes and then can be started again inatantainiously by starting pilot light and away you go until it goes out...


Hello,
Here's a few things to check. When you light the pilot, is it a strong blue pilot flame, a weak blue flame or a lazy yellow flame? Is it heating the thermocouple enough to make it red hot after a few minutes? If the pilot is small blue or lazy yellow flame, it may be dirty and need cleaned. When the burner lights, the weak pilot flame may diminish causing the thermocouple to cool off enough to shut down the main burner. Clean the dirty pilot orifice by using a can of compressed air with attached straw. (The same canned air you use to clean computer keyboards) Blow it into the pilot assembly where the pilot flame burns out from and blow thru the air holes on the side, if applicable. You might also check the thermocouple itself to make sure the tip is not partially burn't off. It should be a smooth, rounded tip. Replace the thermocouple if cleaning the pilot orifice doesn't solve the problem. Douglas

Why does the pilot light keep going out?


Make sure your pilot flame is hitting the thermocoupler. If not then use air to clean pilot port and try again.

I HAVE A VERMONT CASTINGS RADIANCE HEATER MY PILOT LIGHT WONT STAY LIT I HEAR THE THERMOCOUPLER TRIP THE VALVE BUT THE FLAME WILL GO OUT


We had this problem and struggled with it for over a year. We finally hired someone to come in and service the stove he cleaned everything and blew a piece of crud from the pilot line. NO Problem for 2 years since.
He told me the pilot light should look strong pointed like a pencil not curved up like a candle. He removed the pilot and disassembleed the line and used compressed air.

Pilot light keeps going out


Dan, Since you just had the tank filled and the heatewr installed a tinty piece of trash could have entered the pilot orfice. Un do the lower floor panel take off the pilot assy. Blow out the small pilot orfice. Blow reverse from normal gas flow to unlodge the debre. Re asemble and light.
If this dosen't work It may be the pilot air intake is too open causing the pilot to blow itself out.If thats the case close off the air adjustment some. It will be located behind where the flame exits the pilot orfice.
