Whether you are in possession of a stove or a gas oven or a kitchen free installation, if fitted with a safety valve and this is bad, when are you going to release the tap knob, the flame will go out.
The flame goes out – Thermocouple.
Most of the time, when the defect responsible for the number one is the thermocouple.
the flame goes out
Take for example a stove, each knob has under him a faucet that shuts off the gas, and every tap brings the gas to the stove correspondent.
When you press the knob and turn it around, the gas flows and the spark ignition is turn on the stove, then the flame goes to heat the thermocouple, which is located right next to the stove.
The thermocouple is connected to the tap and warming energizes the valve mounted inside the tap, in doing so leaving the gas passage open.
If the thermocouple fails, the valve of the tap is energized and when are you going to release the knob and the valve will close the gas flow with the result that the flame will go out.
The flame goes out – Replace the thermocouple.
Get the thermocouple, close the gas, turn off the electricity and removing the work surface.
Always use gloves, the sheet metal is very sharp and cutting is a snap.
Usually the thermocouple is fixed with a nut at the burner cup on one side and screwed to the valve on the other side and can be removed with a wrench size 8.
There are various types and may be fixed in other ways, to understand what tools you need to disassemble the first floor you just watch the thermocouple purchased.
Find spare parts for any appliance at an authorized service center, you will need to get the model and in some cases even freshman and industrial code before heading into the store.
I usually phone to avoid a ride in a vacuum, so if you do not have the part in stock I do it to order.
I suggest you also get the grout again, when you go to remove the piano work tends to come off and is in poor condition.
Before remounting the work plan tries to turn on the stove to see if it works, be careful not to take the power.
The flame goes out – Causes.
If the thermocouple is not bad, the reasons for which the flame extinguishes are five:
1) The shaft of the tap does not arrive correctly at the stroke end;
2) The thermocouple is loose.
3) The faucet valve is faulty.
4) The flame heats the thermocouple well.
5) The faucet is faulty.
The flame is extinguished – Tree faucet.
It usually happens when the stove is new and the ramp (tube) to which are connected the taps is slightly crooked.
Consequently the tap is too low and the knob on instead of completely crush the shaft of the tap is prevented by the work plan.
To verify, pulls the handle and squeeze the shaft of the tap for a few seconds if the flame goes out equally this is not the reason, if it stays on you just shim with a paper ball knob.
In this way will be more elevated and will not be stopped out by the plan work.
The flame goes out – Thermocouple loose.
In other cases it happens that the thermocouple is loose or from a part of the tap or in the final part of the piece, the visible part.
In both cases will need to disassemble the work plan and tighten or the part that is screwed to the tap or the nut that the stops at the burner cup.
These two cases are more frequent when the hob is new, so if you are in warranty does not put us hands and call for service.
The flame goes out – faulty valve.
If you came to this point means that you have already tried to replace the thermocouple and the flame goes out the same.
The valve is positioned inside the tap, when it is not defective remains energized and closes the passage of the gas.
I recommend this work only the most experienced and proceed with extreme caution, however, you will go to work on the faucet and if you mess something may leak gas.
If you decide to proceed with the responsibility is yours.
To replace it you will need to remove the work surface, turn off the gas, turn off the power, disconnect the thermocouple from the tap and unscrew the nut with a wrench.
Inside you’ll find the valve that will simply show and replaced, so everything comeback.
In some cases damage as a spare the whole faucet, you should remove the valve from the faucet again and put it on the old one is easier than replacing the entire faucet.
Before closing a prepared glass with dish soap and just a dash of water, mixed with a strong brush to create a foam that you’re going to move on the part of the faucet you have removed.
Open the throttle and see if bubbles form, if nothing happens you can put it back together, but if you see the bubbles swell means that you do not have reassembled in the correct way the faucet.
Dries the foam and try to turn on the stove, if all went well the recovery plan of work.
The flame goes out – The thermocouple does not heat well.
Especially in gas ovens may happen that the minimum is set incorrectly and the flame does not touch the thermocouple heats up well does not intervene security, then the flame goes out.
In this case you will need to adjust the idle speed by turning a small screw located on the faucet, you should see it by removing the knob.
In other cases, the minimum is set well but the thermocouple is defective and causing the shutdown of the oven.
Especially in the new ovens may happen that the thermocouple is positioned poorly and is too far from the burner, just slightly bend the bracket that is attached to the burner.
If you are covered by warranty not get their hands and call the technician.
The flame goes out – Tap defective.
When the tap is defective must not be to insert the valve and let the shaft of the tap when the flame is extinguished.
Hardly is the entire faucet to be defective but it happens too, so if you tried to change the thermocouple is that the valve and the burner shuts down anyway, you’ll have to replace the entire faucet.
