Constant Gas odor

Sometimes theres too much air in the line. A better connection from tank to stove may help, or your running low on propane. Try cleaning the burners with an old toothbrush removing built up sut. Your flame should burn blue, not yellow. Hope it helps!

has to be an internal leak in the ovens tube

Hi Bunny.
Now, about your oven.
If you spilled some juice into the oven on Thanksgiving. It will be dried up by now. However the lower burner in your oven should have a shield over it so that juice doesn't get onto the burner.
If the oven is now working properly in bake mode, then the same burner will work in self-cleaning as well. Whenever you turn on a gas appliance you will smell an an oder for just a moment.
Here is the reason. Gas is odorless naturally. The gas company intentionally puts what is called an "ODORANT" into the gas so that anyone can smell a leak. Sometimes, they put too much oderant in and they get quite a few phone calls about leaks. Of course, when there is a real leak, they can also find out about it and take care of before there is any danger.
Your caution in not listening to your son's advice is wise. "Just do it" applies to Nike shoes, and sports. When it comes to safety with regard to natural gas, electricity, or any fuel (like gasoline) "Just do it" can be just fatal. Remind your son of that.
I hope I've helped you. If you have any more questions of me, you are very welcome to contact me through this site.
Best Regards,

Hi,

There could be a couple things that would cause your symptoms, I will do my best to try and explain each one.

First off I am assuming from your dialog that everything is cooking the same on the top and in the oven, the times are the same the flames on the top burners look or sound no different. If this is the case the repair outside would not have a direct bearing on a 'problem' but it could cause the odor. Here is why...

Natural gas has no odor a chemical called Mercaptan is added to the gas to make a leak easier to detect. The amount of Mercaptan is regulated closely so it all is consumed in the flame. If there is too much you will get an odor from the flame.

The Mercaptan can line the inside of the piping that feeds gas from the regulator to the range. Working on the pipes can break loose some residue that may have a stronger presence of odorant causing you to smell it for some time. It will eventually go away.

The second thing that could cause this odor is if you have done any remodeling in the home, paint fumes, stains, oils many other chemicals can mix with the gas and cause this Mercaptan to not be burned up all the way and create an odor.

I hope this helps

if this is fairly new, there is a hot surface ignitor near the back of the burner in the bottom part of the oven. This can go bad. There is a connector that can be pulled apart where the ignitor meets the wiring harness. Ohm out the ignitor or have someone with a meter ohm it out. There should be resistance and not open. If open the ignitor should be replaced. If you have a broiling element, turn that on. If the broil element comes on then the ignitor is almost for sure the problem.

There is a problem with the regulator or the thermal bulb you need to call a repairman in to replace it, if you have a gas smell it is allowing the piolet light to have gas comming out and not lighting this is DANGROUS do not put it off get it looked at right away. This can kill you.

You gas oven uses a glowbar to both regulate and ignite the gas entering the oven. If this glowbar is faulty, it might let some gas into the oven but it is not hot enough to ignite the gas. That is why you are smelling gas. I would suggest to start by replacing the glowbar (and if this is not the solution, simply return the part for a refund). The part you are looking for can be found online here: http://www.partselect.com/PartDetail.aspx?Inventory=470129&SourceCode=1

It is quite easy to replace. Simply remove the free-standing pan on the bottom of the oven, unscrew the existing glowbar, remove the back cover from the stove and trace the two wires that belong to the glowbar and unplug them. Thread the two wires from the new glowbar through the opening and reconnect to the plugs at the back of the stove. Screw in the new glowbar and test. Most oven ignition problems are caused by faulty glowbard. Good luck.

you may need new coupler on pilot system

I've had ignitors fail that way, they don't always just burn into an open circuit. I'd advise replacing it. 

i think you probably have a weak ignitor. does the ignitor glow orange?
if it does, or i should say when it does, just tap lightly on the gas valve and see if that causes the gas to flow into the burner and then light.
you can use the handle of a screwdriver to tap with and it wont need to much force.
if this does work, then just replace the ignitor. when they get weak they will glow, but wont draw enough current thru the gas valve to allow it to open. your valve does get voltage but it opens when enough current draw opens the bi-metal portion of the valve to allow gas to flow.
