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.

U can light the pilot lite,turn 2 ON it will stay lit 4 a couple of minutes then go out? If u turn the knob 2 low,med. It goes out pretty much immediately?I changed the thermocouple,blew the lines ou


Is the thermocouple secure, routed properly, no kinks, no sharp bends? Is the end of the unit properly aligned so the hottest part of the pilot flame is hitting the unit. Did you hold pilot switch in the light position for at least 30 seconds, before you set the gas valve to on? If all above OK, try this. Light the pilot using barbeque lighter once it lights keep the lighter on the t-couple for 30 seconds, then set the valve to ON and keep the lighter where it is. Once the main burner lights, remove the lighter. If the burner and pilot go off, your gas valve is bad.

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

Light pilot on Royal deep fryer. Pilot will not stay lit. Second fryer has larger pilot have no trouble keeping it lit. How can I adjust the pilot so that it will stay lit?


there is a small adjustment screw on the gas valve,turn it clockwise to increase pilot,if that does not work the vent cap on the gas regulator on the back of the unit could be stopped up,remove that cap ,clean out or replace unit can operate without it just fine.If you increase the pilot and it still wont stay lit replace the thermocouple

After heating pilot goes out . my igniter is bad so i light manually and after heating main burner shuts off and so does pilot


The thermocouple that controls the gas to the pilot light must be bad. The thermocouple, when it is heated by the pilot light keeps a valve open that keeps gas flowing to the the pilot light. This thermocouple closes the valve that supplies gas to the pilot light, this is to prevent gas from continuing to escape when the pilot light goes out. This is a safety issue, I recommend that you call a professional about this problem. You might be able to repair it your self by replacing the thermocouple but I still recommend that you have it checked by a professional.

Pilot wont light


If the pilot light goes out when you release the primer,then the thermocouple is bad.You can try to adjust the thermocouple,if it can be.It needs to be in the pilot flame.If the thermocouple is not in the flame,it will not stay lit.If you can not get the pilot to light at all,with the primer pushed down,then replace the regulator.To light the pilot light,you need to turn the dial to pilot.Then press the primer button down and hold it.The primer is either built into the turn knob,or it is a res button.Hold the primer down,and light the pilot,continue holding the primer down for at least 40 seconds.Then release the primer slowly,and if the pilot light starts to get weak,and try to go out,then push back down,and hold 30 seconds more.After the pilot stays lit,turn the knob to furnace or low,or whatever the directions say.

Pilot light won't stay lit.


Ensure that gas is getting to the pilot , or you may have a devective pressure regulator.
If gas is getting to pilot and pilot is turning off, then you need to replace the thermocouple.
The thermocouple function is to turn off the gas if there is not enough temperature, so to prevent gas leaks if the pilot light goes off.
Near to the pilot light there should a part similar to a small metal tube directly in contact with the flame. Thermocouple is wired back to the gas valve.
When the pilot is on, and temperature is steady, the thermocouple will generate a small voltage that will keep the gas safety valve open. In case the pilot light goes off, the thermocouple will cause the valve to close. When you hold the pilot light button , the thermocouple will normally reach enough temp to keep valve open.
If the termocouple is faulty, it will turn off as soon as you release the igniter button.
Replacing thermocouple is an easy repair.

Call the number listed on the owners documentation to get the replacement part.

The pilot light on my gas water heater continually goes out. I can re-light the pilot and get it going. The gas burners goes on runs for awhile. I'm assuming when that when the temp hits the desired temp...

The pilot assembly should look similar to the pic above. Depending on where you live, you may be required to hire a certified plumber to replace the parts. If not you can do it your self. Keep in mind if it's not staying lit you also need to check the thermostat and the thermocoupler before replacing the pilot assembly. There is a good chance it is just the thermocoupler going out. It is one of the first things to check when troubleshooting a pilot light problem with a gas water heater. A thermocouple determines if the pilot light is lit. If it's not lit, the gas valve fails. If that's the problem, replace the thermocouple.


  1. Shut off the gas valve on the water heater and the gas valve on the line near the heater. Remove outer and inner doors, and loosen the pilot and supply tubes and the thermocouple connections to remove the burner assembly.
  2. Step 2 Loosen the screw holding the thermocouple to the bracket. Remove old thermocouple. Bring it with you to the store to ensure you are buying the proper replacement.
  3. Step 3 Install the new thermocouple. Position the thermocouple so that the pilot flame heats 1/2 inch of the tip.
  4. Step 4 Reinstall burner assembly in the water heater. Tighten burner supply tube, pilot tube and thermocouple connections. Tighten thermocouple no more than a quarter turn more than hand-tight.
  5. Step 5 Turn on both gas valves. Check supply tube and pilot tube for leaks with soapy water. If soap bubbles, tighten connections to fix leak. Ignite the pilot light, and make sure the thermocouple tip is heating up. Replace inner and outer doors.
