This can be caused by a weak/inop hot surface igniter ,defective gas control valve or debris in the burner orfice/venturri. The gas odor is going to be caused by unburned gas due to a by-passing gas control valve or a weak igniter(not lighting the gas coming from burner) First you will need to verify that the hot surface igniter is coming on(you should see it glow in the burner compartment). If it is not glowing then you will need to verify that the wiring harness has voltage to it when the oven thermostat is on. Also check the igniter for any cracks or damage and if found then replace the igniter. If it is glowing then one thing that you can try(be very careful doing this) is to give the gas control valve a light tap with something hard like a wrench when the oven is turned on,igniter is glowing but the burner is not on. You will need to remove the broiler/storage drawer at the bottom of the oven. Once you pull the drawer out you should see the gas control valve at the back of the range. Try turning on the oven and lightly tapping the valve housing after the igniter is fully on. This may loosen up any debris inside the control valve housing that might be causing the by-passing problem. If the oven burner comes on when tapping the valve then try completely turning the oven on and back of several times. And when I say completely I mean turn it on after the igniter is not glowing and burner has shut off. This works about 30% of the time. If the burner control valve sticks again after trying this procedure then it could be the control valve and/or the hot surface igniter defective. The hot surface igniter would need to be disconnected from it's harness and tested with an OHM meter. Most igniters should have a 500 to 700 OHM reading. If you get a reading that is way off then the igniter is defective and replace it. If the igniter tests good then the gas control valve is suspect and replace it. Most appliance parts retailers will test your igniter for free. When the igniter is on it should glow very brightly. If it is dim then that is a sure sign it is bad. Also inspect the burner venturii and burner orfice for any possible debris(grease,lint ect) that could be restricting gas flow. One more thing you can try is to manually light the burner. Make sure the oven and burner compartment are COMPLETELY cleared out of gas. Then make sure there is a flame from a match or lighter right next to the burner where the igniter is located(it is best to use a long fireplace match) before starting oven. Once the flame is lit and next to the burner then turn on the oven thermostat and listen for the flow of gas. Once the flow has started the oven burner should light immediately! If the burner does not light within 2 seconds the remove the flame and shut down the oven. If the burner lights with the match then either the igniter is not hot enough to light the burner or there might be a restriction in the burner head blocking the flow of gas to the hot surface igniter...or a restriction in the venturri or orfice. You will need to be extremely careful performing these procedures! If you are smelling gas then the oven and burner compartment could fill up with enough gas to cause a delayed ignition! You could get burned or seriously injured so I advise you not to try these procedures if you are not experienced with gas appliances. You are taking your own risk trying these procedures and if you feel uncomfortable trying these then I suggest call a professional.
Hi,
Here is a tip that I wrote that will help you with that problem...
The ignitor for your burner is going bad...
Yeah, sounds crazy but it happens that way...
