Re: burners well not light up right and pilot lite is...
Two possibilities: This is a stove orificed for propane and connected to natural, or the regulator ( a squarish shaped thing in the line under the cooktop) has a problem and is limiting gas flow way below normal. In the first case you just got the stove, in the second it has worked fine until the sudden change.

Pilot flame has to hit the thermocouple. If pilot is dory flame.will be weak and not reaching the thermocouple that tells the oven there is a flame and opens the burner. If the pilot is strong and no gas to burner than that thermocouple. ( 100% safely valve is worn out) replace that and you are good
If you light your pilot light, hold in the button and then when you release it and the pilot light goes out, generally you need a new thermocouple. Gas repairs can only be undertaken by a qualified gas technician so you can't do this job yourself.
The thermocouple is a safety device that recognises that the pilot has a good flame and is enough to ignite the main burners. The thermocouple open that valve to the burner.
In limited circumstances the thermocouple doesn't need replacing, either the shield that aims the flame to the thermocouple has become dislodged, or the pilot jet is a little blocked by debris. Either way, having the appliance serviced by a qualified gas fitter is the way to go. I am sure you will have seen news stories about explosions caused by gas leaks and faulty appliances.
The flame sensor is attached to the pilot light. It's down on the right side of the burner tray and usually has an orange wire attached. The flame sensor lets the heater know that the pilot light has been lit and it's okay to open the main valve.
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.....
You have a bad flame sensor or a bad burner graound... the gas valve porves the flame by passing a very small current through the pilot flame... yes flame does conduct electric...if the sensor is dirty or bad or the ground wire to the burner is corroded the gas valve does not sense the current and "see" the flame.
Hello, Your right side burners probably have small vertical lighting holes that are clogged where the pilot lights the burner. Use a sewing needle to poke each hole clean. While you're at it, poke clean the horizontal burner holes just to make sure they are not clogged either. Are there also little tunnels from the burners to each pilot flame? Make sure those are clean inside and attached properly on each end. The pilot flame should be approx 3/8" tall. Compare the working pilot flame to the non-working pilot flames and adjust as necessary. Each pilot has a small aluminum tubing running to it, the adjustment screw will be on this tube. You'll just need a small flat head screw driver to turn it counter-clockwise to increase flame. Hope this helps. Let us know if we can be of further assistance. Douglas
There are actually two pilot lights to light, (maybe three) Under the top there would be the old style flash back tubes leading from two burners to a pilot. This small flame stays lit while the gas is on. When you turn a burner on some gas flows back through the tube and flashes or lilghts the burner. When you turn the gas on there is always gas through the pilots, unless shut off with the little set screws if you follow the lines. From the factory these are on and open. Small set screws also adjust pilot flame size. THe other pilot for the oven is down by the main burner. There is a small cap tube from the gas valve to a holder just under the burner. This is where it is lit.......... There is another line to the thermostat when you lturn it on that opens more gas to increase the pilot to a biggger flame to open the gas valve burner assembly. .Also ranges usually come set for natural gas, and you have to do spud adjustments, regulator, air flow only if you want to change to lp...... Put a new flex line on, and be careful with gas...........
