Psycho oven keeps shutting down
Posted 16 August 2005 - 03:28 PM
So here I am gas oven won't heat on bake, but broil works fine. I get to looking around and I can tell that since one works and the other doesn't it must be something in the bottom burner which I associated with bake because I am smart like that. So I figure this little glowing thing isn't getting hot enough go out to sears parts central and buy me a new one, damn thing was $73 including tax. Guy gives me the lecture about not toughing the ceramic looking part, great it is sort of surrounded by a metal cage, like I was really going to pry that open just to mess with the complicated looking part.
So I take like 4 layers of sheet steel out of the bottom of the oven to get to the little glowy thing some come out the bottom some come out the top. I change it no big deal. Then I turn the gas and power back on and try the bake works like a charm. Well I thought it worked like a charm it glows REAL bright the gas comes on and makes fire, fire good before no fire. However my wife bless her heart has put up with me changing the part took me a month to get motivated, cooked with it tonight. She said if you leave it on it will go off after a few minutes.
Of course I don't believe her so I have to check it out for myself. Sure enough I hit the bake button on the electro display 350 and bake again. I see the glow through the cracks in the bottom of the oven hear the gas and viola we have heat. Things look great, I wait. It got up to 185 then the whole damn oven shut down. The clock and all so something happened when it got hot that shut down the power to the oven, and that is where I am now.
I am fairly confident that I diagnosed the original problem of the ignitor coil having gone bad, and I assume that now something is overheating and shutting the oven down, but I don't have any idea what. I used to be a automotive sheetmetal worker and I thought I had done a good job in disassembly and reassembly, but maybe I put something in wrong.
Any help would be appreciated, I feel like a bonehead to call a repair guy now that I have screwwed it up myself.
Thanks in advance

sorry I know how critical that 1 is

It also sounds like the problem is a blown thermal fuse. Can't be sure without looking at the wiring diagram for your range, which is cleverly hidden inside your range-- the pots drawer is a common hiding place. Get it, post a legible and properly oriented copy here.

Unplug the range, open the control panel and get it stable so you can poke around in there with your meter, then plug it back it to make the reading. You're looking for 120v wrt neutral in the wire labeled "L" on the ERC board.

I know that sounds moronic, but I wanna make sure, just looking at it I have taken off like all the screws that are easy to get to in that area and it is still rock solid.

Lemme multi test it.

Just wanted to make sure that I clarified that I do get display, until about 3 minutes after turning bake on.

Ok, I'm suspecting some heat-related wire connection problem. These are notoriously difficult to track down. I would start at the "L" wire on the ERC and work backwards to the first wire harness connector that I saw depicted on the schmatic. Wiggle it, jiggle it, take it apart and reconnect it. Then try running the oven again.

I used my normal method of firmly twisting all of the wires clockwise seperately, then clockwise together then screwwing the wirenut on clockwise as well. I don't know if that is how you are supposed to do it just how I have always done it, but then again I have never done work on an oven before. Think I might have messed those up?
I also wondered whether the polarity of the device would make a difference, however I could see no markings on either coil to indicate so I guessed.

I am gonna let it run for another 20 minutes before putting it together. Thanks to all your help, I'll throw some beer money in.
