When you light the pilot, are you holding it down for 30-60 seconds. When you release the pilot button, does the pilot flame stay lit? Or does it only go out when you turn the knob to on position. Make sure the pilot flame is heating the end of the thermocouple and that it's a strong blue flame, not a lazy yellow pilot flame. Make sure the tip of the thermocouple is not burn't off, which usually happens with lazy yellow pilot flames. Replace thermocouple is nothing else works.

SOURCE: pilot light goes out after when unit turns off

Either you have a weak gas valve that will have to be changed or thir may be a partial blockage in the vent system or crack in heat exchanger. Does the flame change when the blower comes on? If so, crack! Check the venting system to make sure it is getting good fresh air and no exhaust is being sucked back in.

Why doesn't old Sears Gas heater turn on consistently?


If the pilot light is too small a flame, or the thermocouple sensor is too far away, it won't light. I suggest you find the small screw that adjusts the pilot light flame size, and increase it slightly. Quarter turn CCW.

I have a VC Wonderfire model 2610. The pilot flame is perfect blue on both sides... however, when I hit the switch for the main burner to come on...the pilot goes out... any ideas ???


You may have moved the safety sensor or pilot flame tip. The pilot light heats a wire. The wire is the safety sensor. The wire has to be clean and in the pilot flame near the flame tip.

At 300F after half hour, pilot and main gas burner was going off. When re-lit would stay on only 5 minutes thereafter. Had the thermopile changed(bought locally- not original from Imperial but identical),...


Hi there.
The thermostat will only shut down burner flame but not pilot flame.
Try tightening all wiring connections.
By using an ohm meter, check the continuity across the hi limit terminals when the pilot goes off, your hi limit may be tripping prematurely causing pilot flame to shut down.
Regards.

Pilot light goes out when gas turned on


I am assuming that you are saying that after you have pushed the pilot knob down and the pilot lites and stay lite and then you turn the knob to turn it to ON the pilot goes out...... Then the Gas Valve is bad and will have to be replaced....... Or if you are saying that the pilot goes out when the burners come on then you may need to replace the Thermocouple because the main burner flame is pulling the pilot flame off of the thermocouple and it is weak and will shut the gas off.... Or You could have a cracked heat exchanger that when the burners are on and then the blower comes ON and is blowing the flame around and blowing the pilot flame off of the thernocouple......which will shut the gas off....and then you will need a new furnace or New Heat Exchanger...... These are the most common problems Hope this helps.....

The pilot light goes out. When I go to re-light the pilot and turn the temp for vacation to medium the flame goes out again.


The pilot light jet may have got a little bit of dirt or grit in it which is preventing it from keeping alight. Try probing the jet with a fine piece of wire to see it the blockage can be dislodged. You may have to unscrew the jet to clear it by blowing air through it. Make sure gas is turned off first before removing any parts.

The pilot light also has a thermocouple that allows gas to the pilot light while the flame is burning. If flame goes out it shuts gas off to the pilot jet. The thermocouple is bypassed by a switch during the initial ignition and once the thermocouple warms up after a minute or two of holding in the bypass switch, it should maintain the pilot. If, after cleaning, the pilot light keeps going out, it would seem that your thermocouple is faulty and needs to be replaced

THE flame from the pilot should shoot past the thermo-couple and heat this up and make a small amount of mili- amps to prove the pilot light is lit. ..So if the flame doesn,t go past the thermo-couple it won, make mili-amps or its tme to change out the thermo-couple, They only cost lest than $8:00 and you can change it!

Pilot goes out


If the pilot won't stay lit, the thermocouple may be loose or faulty, the pilot orifice may be clogged, or the pilot light's flame may be set too low and needs to be adjusted. You can clear a clogged orifice with a piece of thin wire, such as a bread tie with the paper stripped off of it. Be sure to turn off the gas to the furnace first! Also shut off the switch or circuit breaker that controls power to the furnace. Just poke the thin wire into the tiny orifice where the pilot flame normally burns to knock off any ash or debris. Some pilots have a flame adjustment screw for adjusting the flame. To adjust this, refer to your owner's manual. Normally, this is simply a matter of turning the flame adjustment screw to achieve a full, steady 1 1/2-inch to 2-inch flame that doesn't have any yellow in it.
