Kenmore gas oven

I have a six year old gas oven that almost explodes when you turn it on. It has been taking longer and longer to preheat and now when I turn it on the oven makes the boom sound after being started a few minutes. I now leave the door to the oven open so the door does not blow open. Any ideas as to what I can do myself to fix it? THANKS

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

The condition you described is commonly refered to as delayed ignition. A serious condition which must be corrected.

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

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.

Ignition 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.

An 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.

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.

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.

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

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.

Another possible cause is the glowing hot surface ignitor is too weak to provide enough of an ignition source. Replacing the glow ignitor should resolve the problem. Cleaning the burner is also suggested while in the process of replacing the ignitor.

I also own the exploding Kenmore stove, mine is a 362, blew the door open, burnt my Wife's arm and bruised her leg. Kenmore has never herd of this before, ya, right. I've contacted the consumer protection agency and filed a complaint about this potentially dangerous device, I've asked for a full investigation as there are dozens of complaints about Kenmore's exploding stoves. I would not play around with this, you are basically using a cannon, here is the link to the consumer protection agency, file a complaint with them, God only knows when one of their bombs go off and it kills some one!

Hello: omtunion. Welcome to the Do It Yourself web site and the Gas Appliances forum topic.

Glad you joined and are willing to offer some helpful advice. Problem is, this post is dated 2003. Member whom posted it is likely long gone. Possible other members with a similar or like oven problem may read it and gain some helpful info from your post. Not as likely as with a newer posted thread but possible. Thanks.
