    I have a gas craft gas heater and once I take my hand off the heater level knob that you press to ignite the heater turns off. Thanks

    I have a pyrox 303 gas heater that will not stay on after you take your finger off the ignition button most of the time. You can get it going eventually and it may be fine for ages then it will turn itself off. Then the whole process starts again.

    I also have a similar problem. After starting the heater and removing your finger from the LPG supply starter button the flame goes out. Any solution to this problem?

SOURCE: I have an old gas

Old heaters that have a "standing" pilot light that burns all of the time use a device called a thermocouple. The thermocouple sits in the flame of the pilot and when heated by the pilot, produces a very small amount of electricity (approx 30 mV) which the heater interperets as proof that the pilot is burning and indicating that it is okay to turn the main burner on. The thermocouple is a part that wears out and when it fails causes the exact problem that you are describing.

your pilot has dust in it. Use a drinking straw and blow air across (not into) the pilot opening. this will remove the small particles of dust that are stopping up the membrane inside the opening. THis will make your pilot flame bluer and hotter and keep the thermocouple hot enought to produce enought magnetism to hold the gas valve open.

Hi and welcome to FixYa, I am Kelly.

What you are experiencing is the lack of a signal from the thermocouple to the gas valve. I.e. the thermocouple is not passing heat information at all. This is caused by either a defective thermocouple, a dirty mating area where the thermocouple connects to the gas valve or... an improperly positioned thermocouple that is not "in the flame" with the pilot lit.

  • First make sure the FIRE end of the thermocouple is in the flame when lit. (reposition if necessay)
  • Next disconnect the thermocouple by unscrewing the fitting on the top of the gas valve. (No gas will come out) Clean the metal mating area as best you can and then re-install the thermocouple. Just a good snug fit. Once you feel it come snug add 15 degrees of tightening motion with a wrench.
Attempt to light the pilot... wait 45 seconds to 1 minute while holding the pilot button down before letting it up. If it stays lit.... GOOD JOB. If it goes out the next step is to replace the thermocouple. If after replacing the thermocouple it does not stay lit the remedy is to replace the gas valve. There are no short cuts and the sequence of repairs is just as I stated in order.

You can remove your old thermocouple and walk in to almost any appliance parts supply or Plumbing and heating supply to purchase the correct thermocouple without a part number. They will match it up with yours.

Thanks for choosing FixYa,
Kelly

SOURCE: HI there,Gas Heater has been

This heater has a safety system: the gas valve has a thermostat that closes it automatically when the flame goes out. This system uses a sensor that needs a bit of time to heat up and trigger the safety - keep the valve's button pressed for about 10 seconds after lighting the flame to allow the sensor enough time to heat up.
If even after 10 seconds the flame shuts down after you lift the finger from the button then the safety system is defective and it will have to be replaced. Because this is about gas the repair must be performed by a pro. Luckily this is a simple job and the part isn't very expensive - all shouldn't cost more than $125.

The piolet light will not light. If I turn the


You may have a plugged orifice in the pilot tube assy. If you have any way of getting to the orifice with compressed air, and blow back, it may dislodge it, if it is plugged. If possible, carefully remove pilot tube at valve end first, so that if it is debris in there, it blows clean of the tube, so it won't clog again. Otherwise you'll have to remove complete assy. Another thing to try as well, is to shut valve off, loosen fitting at valve for pilot tube, AND MAKING SURE NO FLAME OR SPARK ANYWHERE IN THE AREA, take a spray bottle with dish soap and water mixed (bubble tester) and then spray at pilot fitting when it is loose, and push pilot, to see if any bubbles appear, indicating gas flow. If no flow there, then I'd get a new gas valve.

I have DCS FSF-40N fryer. the piolet doesn't stay on when I release my finger it goes off I tried to change the gas valve from different brand and I only replaced small part where the electrical wire is...


You must first check to see if your pilot flame is good. If it is too weak, or not impinging properly on the thermopile, it will not stay lit. If the pilot flame is ok, the problem could be that the thermopile is weak. using a millivolt meter, test the voltage across the thermopile while the pilot is lit (you may need someone to hold the button down while you do this). You will also need to disconnect the thermopile's leads from the control while you do this. You should get about 750 millivolts across the thermopile while the flame is on it (let it heat for a while to stabilize). If your reading is too low, your thermopile may be shot and needs to be replaced. That is of course only if your flame is proper. That voltage is needed (or close) to keep the magnet open so it will stay lit when you let the button go.

PILOT LIGHT WILL NOT LIGHT


the thermocouple not only keeps the pilot on but lets the gas valve know its okay to open on a call for heat, remove your thermocouple and clean it with a fine grit sandpaper and if this doesn't work replace it all together.

How flem sensor works in furness


After you hearthe click from the ignitor your piolet will light. the flame sensor (mounted next to the piolet (tip in the flame) ) will sence the heat from the piolet sending a milivolt siginal back to the ignation board. once the board knows there is a piolet and the system is safe the main valve will open igniting the burner trays.

Pilot light wont lit up


Change The Thermostat Cause If Your Getting Gas But The Water Heater Doesn't Detect The Heat It Will Close The Valve. When Lighting You Hold The Button Down For About 30 seconds so the thermostat will detect flame and stay lit. Check To Make Sure The Thermostat Is Where It Should Be. Heres A Picture Of What It Will Look Like.
