My gas oven will light most of the time properly and every so often it will seem to light partially and I smell gas. The electric flash starter is red and hot and the gas is coming out but will not light. Is there anything that I can clean or adjust to work properly? Model # 790.71672100 Serial # VF12801326

Re: Kenmore Gas Range
The igniter needs to be replaced. I had the exact same thing happen to
my oven. The igniter would glow, but after tested, it did not have
enough amperage to actually ignite the gas, so the gas kept running
with no ignition

Most of these new fangled gas stove feature a silicone carbide ignitor to light the oven. Older stoves used a standing pilot light. As silicone carbide ignitor age a little they tend to get weak and fail to open the gas safety vave sufficiently enough for ignition. Take a look
Doubt that the glow plug is bad. Gas only needs about 1100 degree F. to ignite using the glow plug method. It really seems as if there may be no gas getting to the burner. If there is no flame, you should be able to smell gas. If there is no gas smell, then I would look for the obvious such as: is the gas turned on?, Does the gas valve on the unit have a safety that is tripped? and so on. A new gas valve may be in order but make sure that it is receiving the proper voltage when the glow plug is on. Lastly, there may be a safety that is malfunctioning. If the unit does not light within a given time, the safety will "Lock Out" the unit so the place doesn't fill up with gas.
Hope this helps and good luck.
When you smell gas...is it all the time? If so, this is dangerous. If it only happens when you're trying to start the oven, no problem. Push the red button and hold it while lighting the pilot. Hold for 30 REAL seconds more. Release. The pilot should stay lit. If not, get a service tech.
The gas regulator valve would also be my first guess. It seems to not be allowing enough gas into the system. When the top is on, only a small amount of fuel is required, and when properly mixed with the air all is well, but when you also put on the oven, the regulator won't allow enough gas into the system, so it's "burning lean". I'd get it fixed before it pulsates so bad that it actually blows out the flames and you're left with a propane smelling dangerous house.
