Oven igniter causes small explosion

Installed a new igniter in a GE oven/range and when I turn it on it takes approx. 1.5 to 2 min to ignite the gas. When it does the broiler sounds like it explodes. I was wandering if the igniter needs to be in a certain position in order to lit the gas.

Sounds like the ignitor is worn or mispositioned or the gas mix is wrong.  Could also be a worn burner.  Don't do this yourself unless your fire insurance is up to date.

What causes a loud bang from oven?


If you hear a loud bang the SECOND time you try to light an oven, it means you've just had a small explosion when the gas from the FIRST try ignited outside the heating tube. I would have a professional check your oven before using it again.

Delayed oven ignition


see the next steps and proceed with common sense:God bless you

Fuel Type
If this is a new installation make sure the gas valve has been properly adjusted for the type of gas. Lp and natural gas use different orfices and pressures. A conversion kit is available.

Burner
The burners may need to be cleaned. There are small holes that allow gas through holes that are ignited by the igniter. These holes can become clogged up. You can usually clean these with a toothpick or small wire, watch the video. If it is the oven burner and you have a small flame or it does not stay lit check the video on troubleshooting a gas range.

Gas Valve
The gas valve rarely fails but this can. If the gas burners are clean and the gas valve is properly adjusted replace the gas valve. This should be done by a professional. Leaks can be very dangerous and also the gas pressure needs to be adjusted for the type of fuel you are using.

My GE oven takes a long time to lite. When it finally does there is a small explosion sound. I already replaced the ignitor 2 weeks ago. It worked fine for about 1 week and now I have the same problem...


If the gas valve is opening in a reasonable amount of time then the problem isn't with the igniter and you don't need to bother testing amp draw... Could be a number of things, clogged burner ports near the igniter, incorrect air/ gas ratio, incorrect igniter position (too far away from the burner), incorrect gas pressure. If you can, watch the burner when it lights from a safe distance and see if both sides are igniting at the same time or if it just builds up gas until BOOM! Ha ha, hope you figure it out, be careful.

The oven gas does not come on? Top and Broiler does. Oven igniter does glow


If your oven won't bake, check these:

Bake igniter
Other causes
Bake igniter Usually when an oven won't bake, it's because the bake igniter is weak or burned out. The igniter is a small, round or rectangular device, that's about 1 inch by 4 to 8 inches. It's near the burner itself.

The burner is the tube-type device the gas flows through before it's ignited. It has many small holes on the sides to let the gas, when ignited, form a long, low flame. If the igniter is weak, if it glows red but doesn't get hot enough, or if it's burned out, the gas doesn't flow to the burner and the burner won't ignite. If this is the problem, you may need to replace either the igniter or the gas safety valve. Usually the igniter is to blame.

Other causes Other reasons that your oven may not bake are:

  • The clock settings are incorrect (if you have timed baking or a self-cleaning oven).

  • The thermostat is defective.

  • The safety valve that prevents accidental gas flow is defective.

  • The selector switch is defective.

Oven door blows open during lighting sequence


Hi CL,

This is a common complaint and, luckily has a simple solution. I'll start with the solution and (if you're interested in the "why" of it) conclude with the cause.

First (solution)... your oven igniter has failed.

Second (cause)... Your oven utilizes a "glow" type igniter. In order for it to glow, electricity is applied and the current flowing through it causes it to get very, very hot. This electrical current is monitored by a device called a safety valve. This valve is programmed to open up main gas flow to the burner manifold after the igniter "flows" 2.6 to 3.2 amps.

Igniters are tricky little guys. Unlike a light bulb (which is either good or it's bad) igniters get "weak". So what happens is the igniter gets to 2.5, then to 2.59 then to 2.62, then back to 2.5 amps. It goes up and down. But the 2.62 amp "flow" was enough to open main gas, but not enough to ignite it. So there it goes... up and down. All the while the main gas is opening and closing, but not being ignited. This gas accumulates. Then finally, the igniter reaches it's ignition temperature.

That's when you get the explosion. The "whoosh".

It's not that difficult to replace the igniter. Yours is a part #WB2X9998 and can be purchased at a local appliance parts retailer or ordered online.

PULL THE OVEN OUT SLIGHTLY, REACH BEHIND IT AND UNPLUG IT!!!

Tools required:
1.) 1/4" socket or nut driver
2.) Flat or Phillips screwdriver
3.) Pliers
4.) Wire cutters
5.) Wire strippers

Remove the racks and then remove the "floor" panel of the oven. Then remove the diverter panel/burner baffle. Basically, your goal here is to disassemble the bottom of the oven. You may need to pull the lower drawer out.

After you have gained access to the igniter...you'll see that it's attached to the main manifold with two 1/4" screws (take note of its' position and how it's mounted to the manifold, the new one has to be mounted exactly the same). Word to the wise, here... use a little bit of liquid dish soap on the threads BEFORE trying to un-screw these. This will lubricate the threads and keep them from stripping. If you don't heed this warning and they strip? You'll have to grind them off in order to get the igniter removed.

Wire cutter time... snip the 2 white wires about 3" from the base of the old igniter. Wire stripper time... strip those 2 wires about a 1/2".

Now the old igniter is out. Pull out your new igniter. Cut any extraneous stuff off the END of the wires then strip them about a 1/2". Now mount the new igniter to the manifold (where the old one came from). Now take one wire (doesn't matter which one) from the new igniter and twist it to one of the wires you cut and stripped while removing the old igniter. Then use one of the ceramic wire nuts (included with your new igniter) and twist it on the exposed wires clock wise. Make sure there is NO WIRE EXPOSED after doing this. If there is, remove the wire nut and cut a small amount of you twisted wire pair off.

ALL OF THE EXPOSED WIRE SHALL BE INSIDE THE WIRE NUTS.

Do the same thing for the other wire. Now tuck all of the extra wire away. At this point, you're ready to test your handywork! Set it to bake and watch her light up (without the explosion tis time)!

All that's left to do now is rebuild the lower oven, grab a coolada and get some cookie dough. I'll be over at 6:00 for snacks :-)

REmove bottom panel from stove. shut gas off for at LEAST 5 min. Longer is better. Then placel open flame above gas nozzle, slowly turn to ignite posiiton. After it is lit, wait 30 seconds and turn to on positon.
If by chance this model doens't have a knob for this, then turn gas valve off for 5 min, let fumes evaporate, light flame, place over nozzle, turn gas on.replace bottom oven panel slowly.
