Gas Range Oven not lighting

when the lp conversion is done , it is normally just a jet size change that is done
however the air shroud has to also be adjusted to get a clean blue burn of the flame
The just jet change results in a slightly yellow flame which is incomplete burn of the gas and that creates carbon build up at the jet and burners causing partial blockage
I would suggest that you call in an accredited gas fitter to check the problem and if necessary , clean the jets and adjust the air shroud

Tappan gas range, TGF334BCWB. I can NOT stop the broiler burner from lighting. I have unplugged the 110 power and I light top burner with a striker. However when stove is plugged in to the power the broiler burner lights and continues to burn. The oven knob is turned OFF. The only way to stop the broiler is to unplug the power.

Your gas valve would be my first guess. Is this broiler (and bake ) lit with a glow coil or spark probe that goes (goes click, click, to light)??
If spark probe, you will have to replace either gas valve or spark board.
If glow bar lights the broil but does not glow, then replace glow coil.

defective ignitor. Oven ignitors can glow and allow enough current through to open the oven gas valve but just not produce enough heat to ignite the gas immediately

The oven gas valve coil has failed Need to replace. Go to repairclinic.com and put in the model and order the coil for the valve. It controls the gas valve.

glow plug needs to draw 4 amps to open gas valve even if it red hot ...not drawing 4 amps replace glow plug

Some gas ranges may take 10 or so minutes to light.
Other than that you may have a defective glow bar ignitor.
If it glows and does not light the reistance in the ignitior has failed.

check both oven ignitor and broiler by turning the oven first, and time the time that the ignitor takes before the flame lights up, it should not take more then 60 to 70 seconds, and do the same to the broiler.the one that takes the longer passing that mark of the 70 seconds needs replacing it 's not getting hot enough to light the burner on time that's the one that passes gas with out igniting. replace that one.

it's time to replace the oven ignitor.

ck your light bulb . and ck with meter see if you geting any voltidge
