Top burners often wont light if oven is already lit
Top burners wont light if oven is lit first.Igniters click , smell gas , no flame. Sometimes will light if you turn to lowest heat setting. Burners light normally with oven off . Oven is more frequently not coming up to temperature , say 200-250 degrees when set to 400. Sometimes , rarely , the burner will seem to blow itself out if you put it on a higher setting. The only repair was a new oven igniter @ 4 years ago.

Re: top burners often wont light if oven is already lit
Hello and welcome, If your range has electronic igniters, then you seem to have one or more bad igniters on top of the range if you have a pilot range then you have a gas restriction or clogged orifice tube. Even if they make the click noise while trying to light they may not get hot enough to draw the gas on a constant speed!
This will need to be diagnosed hands on at your location. But this is the fault!

the burners inside your oven by removing the access panel in the front
of the oven or by opening the broiling drawer, depending on your
if the pilot itself is lit, since some ovens have a small flame on the
pilot at all times that then grows and extends to the burner when the
oven is turned on. The lack of a pilot flame indicates the oven
thermostat is malfunctioning or there is a problem with the gas hose.
Check the pilot itself to see if it is clogged with debris or grease
that could be preventing the flame from staying lit.
if the pilot flame will grow if it is lit by turning on the thermostat.
If the pilot flame doesn't extend, the thermostat itself likely needs
replacement. If the flame is extending but the gas valve is not
opening, the safety valve could be dirty or defective. The flame should
be blue in color. A yellow flame indicates the pilot is dirty and is
not burning hot enough to get the main burner to ignite.
the burner on the top of the oven with a match if the igniter doesn't
appear to be effective. If it lights manually but will not light
automatically, the igniter is likely faulty. Do not do this if there is
a heavy smell of gas in the kitchen, since there could be a risk of a
fire. In that circumstance, turn the oven off, ventilate the room and
call a technician.
for any sounds of gas hissing or a clicking sound indicating the oven
is trying to turn on. If there is no response from the oven at all, the
gas may not be functioning properly and will need to be examined by a
technician for safety purposes
You may have an issue with not getting enough gas. Also it could be that the igniters are bad. Have a local repairman check it out, you dont want to mess around with a gas system without knowing what your doing just for safety sake.
You have to identify the thermocouple by the flame. Some units run sparks constantly to insure that tha flame stays lit. If you see the thermocouple bulb by the flame it is bad and needs replaced (he may have bypassed it also let me know) http://www.vikingrange.com/MEDIA_CustomProductCatalog/m10110_viking_primer_2005.pdf
It would be helpful if you have a multi meter. Sorry you are having trouble with the repair man. I hope I can talk you through this but if he has made a mess it could be 10 times more work for you. Txtooltime@aol.com
If you have a burner lit and gas build up, strong smell etc., my advice would be to stop using the oven immediately! You no way gas should come out, build up, to the point you smell it, Especially while a burner is lit. Dangerous condition.
It sounds like somebody bypassed the flame sensor on the oven, no oven should ever release gas for more than a couple seconds if there is no ignition. This oven is very dangerous and should not be used until it is looked at by a professional.
I have fix that problem before, the oven heat is soficating the top burners, you will have to adjust top burners with the oven on, so that they will light by them selfs.Or put a shield under the cook top section on the back, so that the heat will not come to the burners where they get the oxigen.
I just installed one in my house. I found that when you start the lower (gas) oven you need to turn the dial all the way on to 500*, push the knob in (you should hear the igniters clicking), then even when you see flames coming out of the burner, continue the ignition for 10 to 15 seconds. It should continue to stay lit thereafter.
It is normal for all 4 burners to spark at same time. Often burners won't light even when you can see the spark at them because the burner is dirty. Take a pin and clean out all the holes in rim of burner. Also look for small cracks in white part of igniter. If cracked it must be replaced.
