Kitchen Gas Appliances - Oven Gas Odor

Strong odor of gas from the oven. After setting the temp. of the oven the glow bar glows yellow and the burner ignites. Once the oven cycles and reaches the set temp. The glow bar goes out and the burner goes out. Before the burner relights from the yellow glow bar there is a strong odor of gas. What would be causing this? :(

Hello Cathie. Welcome to my Gas Appliances forum and our Do-It-Yourself Web Site.

The most common reason is resrticted and or clogged ignition ports. Ignition ports are the tiny holes or a slot {Ports} where the burner gas exits the burner tube.

Next most common reason is the burner does not light completely around both side of the burner. Basically the same reason as above. These ports are called "cross-over" ports.

Cross-over ports, {holes and or a slot} which allow the gas to cross over to the opposite side of the burner are clogged, blocked and or restricted.

A wire brush, old tooth brush or similar like tool will clear the obstructions. In some cases, the entire burner tube has to be removed to complete this task, while at other times, working carefully, so as not to bang the glow bar, the task can be completed successfully.

In your specific case, the burner most likely has a cross-over slot.
The slot expands slightly once warm since the aluminum expands. In doing so, it becomes self restricting. A possible cure is to use a thin hacksaw blade and clear the slot but not enlarge it or replace the burner.

TIPS:
#1
If the burner is in a compartment area visable through a closed oven door, with the door closed, turn on the oven, wait till the burner lights and notice if the burner lights on both sides.

#2
If it does not light on both sides and the burner is made of iron, where the flames stop is the problem spot.

#3
If the cross-oven port is restricted or clogged on a round aluminum burner, the burner may have a slot or holes on the top or bottom side of the burner nearest the glow bar or at the end farthest from the hot surface igniton bar and or coil.

Suggestions:
Read the manufacturers online web site for product information, problem possibilities, causes and solving methods, part locations, disassembly, reassembly methods, repair proceedures, and instructions, pictorials and schematics, which may be available online.

Retail parts dealers can also help determine what the possible problem may be. Bring the make, model and serial numbers and stop in at the store. The info will help to determine the possible problem causes. Parts dealers are listed in the phone book under appliances.

Hi again,
Thanks for your reply and help. I did what you suggested. I removed the glow bar in order to remove the burner. After inspecting the burner, there didn't seem to be any blockage. However, I cleaned it anyway using a tooth brush. The cross over slots seemed unobstructed as well. The cross over slots are located at the far end of the burner. (away from the glow bar)
After doing all this. I put everything back together and tried the oven. :( After setting the temp. the glow bar turned yellow, the burner didn't ignite and there is a strong odor of gas. :eek: So I shut the oven off.
I search the internet for the manufacturer but didn't find what I needed.
What else can i do :confused:

Hi: Cathie

Thus far you have done well with your attempt to correct the problem based upon your well described reply. The problem is now my problem by which I mean in regrads to offering you other helpful suggestions and advice. HUMMMMM.

Another possiblity is the glow bar. It may be allowing the gas valve to open and gas to pass but not really be hot enough to ignite the gas. Happens on some occasions but often is rather rare. In this case, having the local appliance parts store test the ignition bar may be worth while.

Another rare but often possible problem could be the postion of the ignitor in relationship to the burner. Too far or too close and this problem occurs, unless the ignitor happens to be bracketed on top of the burner.

Ignitor bars or coils bracketed on the side are sometimes prone to mis-alignment. Even if it does not appear to be or seemingly appear to be possible.

Correctional brackets are available to correct this problem but so can simply slightly bending the existing bracket.

It's also possible the gas valve itself is defective. By this I mean opening up much too soon, as in well before the ignitor is pre-heated to ignition temperature and or the fuse to the ignitor and gas valves is too weak, etc.

To determine all these potential problems takes time, effort and work. Usually a trained service agent is required and worth the fee so as not to have a potential problem of delayed ignition.

Delayed ignition, by the way, is the industries term for the problem your describing. It has the potential to cause a fire and or explosion. Explosion which can break the ovens door glass viewing pane and damage internal parts of the appliance.

FYI:
Use caution with the appliance during any normal oven useages and or during attempted diagnostic checks & repairs until you can be positively assured the condition is corrected.

Regards & Good Luck

This is a common problem and is often caused by a defective oven ignitor. And yes an ignitor can glow and still be defective.

Delayed ignition is more common to occur on initial oven start up but does happen after the oven reaches temperature as well. Since the oven burner ports are not plugged and causing your symptom, replacing the ignitor will likely solve your problem.

Hi there! I came across my post to you from last year. I thought I would give you an update on our stove. After replacing the glow bar we have had no other problems with the stove. We have had a number of great meals come out of the oven cooked to perfection.
However I must say I have discovered an invaluable tool. I have used other forums that you offer to get educated on other projects a home owner encounters.
Thankyou for being there to answer my questions.:p
