Magic Chef Oven flame too large?

August 14, 2015, 10:18:01 pm

Need some advice on this one...... When we lit the oven, (first time) we noticed a burnt smell within a minute or so, the oven was clean (no spills). We immediately turned it to off. After a quick inspection and finding nothing obviously wrong, we re-lit the oven and noticed the flame appeared too large. It wasnt yellow at the tip, just large enough that the blue flame touched the drip pan and spread out along the bottom of it. It appeared that the pan was going to get way too hot.
Question............ Is the flame supposed to touch the drip pan at all? Our old Wedge Wood stove in the Holiday Rambler has a long burner tube and the flame doesnt touch the pan, and has a much smaller blue flame.
This may be normal, I just am not familiar with a Magic Chef.

On any gas appliance, including a stove, the flame should never be so large that it escapes the flame spreader. It would have damaged or perhaps burned through the drip pan if you hadn't turned it off. I don't know if the thermostat valve is adjustable. It seems reasonable that it would be. I know the thermostat valve is no longer available, at least for my Magic Chef stove in my 1991 U300. I can look to see if mine has anything that appears to be an adjustment on it if you want me to.

I just pulled the oven temperature knob off the thermostat valve and saw a tiny screw just above the shaft where the knob was. I suspect that may be the adjustment you need to turn down your flame. It's already broken so it's not like you'll be out anything if you mess it up. A new stove will cost you up to $700 so I'd definitely try that screw to see if it adjusts the flame. If you find a source for a new thermostat valve please let me know because I need one too.

Actually, when I just test fired my Magic Chef I noticed that there isn't any flame spreader like a residential oven has. The flame touches the bottom of the drip pan on my oven too. I use my oven all the time and it hasn't damaged the drip pan at all. I think you've just got dust or crumbs or some kind of food spill inside your oven and the smoke will go away. Keep a close eye on it but give it a try. You've got nothing to lose because the part you need isn't available and a new stove will be expensive. It'll probably work just fine after the dust burns out of it.

What I said at the beginning that gas flames in appliances including water heaters, furnaces, stoves, or any other gas appliances, should never be so large that they escape the flame spreader is still true. It's just that this particular oven is apparently designed to use the bottom of the drip pan as the flame spreader. Typically if you switch a gas appliance from natural gas to LP gas you'll have a flame so large it escapes the flame spreader. You need to change to the correct size jets and sometimes you need to do an air adjustment too. Contact the manufacturer for instructions and to order the correct size jets... Sorry to go off topic but it's a safety thing that some other reader(s) might benefit from.

Blew out the pilot frame so many times finally turned it off for smells and safety and used a lighter for the burners

Scott,
Thanks for the reply, we just tried ours again, there is no flame spreader, like you said, just the drip pan. So I guess you are correct and it acts a a flame shield/spreader. We adjusted the small screw behind the control knob and it shut off the pilot, the screw in the middle of the knob also affects the pilot. Neither seem to reduce the size of the burner flame. We will try it again tomorrow with the pan in place and watch it closely.
thanks for the help,
Justin

Do a manometer check of the propane output. For safety

My stove seems to have two separate pilot flames in the oven. There's a small "standing" pilot that's always on if the knob is set to the pilot position, and a larger "interrupted" or "intermittent" pilot that's only on when the oven is on. It's been 25 years since I had to learn this stuff and I can no longer remember whether it's an interrupted pilot or an intermittent pilot but probably someone on here will look it up and correct me.

What happened to my thermostat valve is the main flame doesn't shut off all the way and it leaks a tiny amount of gas into the oven, just enough to poof once in a while and blow the pilot out, which can be exciting if another source of ignition is introduced to the leaking gas. I can't find a replacement thermostat valve and it's a shame to replace a $700 stove that's in nice condition just for one part, so I installed a ball valve on the downstream side of the thermostat valve to completely shut off the main flame gas. The pilot gas is unaffected because it has a separate line out of the thermostat valve. If any readers have this issue I can take photos and go into greater detail. I've been using my oven this way for months and it completely fixed the problem, as long as I remember the ball valve each time I use the oven. Maybe someday I'll find a replacement thermostat valve and I won't need the ball valve anymore. It's possible there's a generic thermostat valve that will work but I stopped looking once I installed the ball valve.

Bob, the pilot for the top burners will blow out frequently if you have the window over the kitchen sink open. I got in the habit of touching the center of the stove whenever the kitchen window has been open to see if it's still hot. If it's cold I relight the pilot for the top burners or just shut it off until I close the window again. The other windows don't blow out the pilot. I've never had the oven pilot blow out except when the main flame poofs and blows it out, even with the window open over the sink.

Scott whats the model numbers of your stove that neds the gas valve?

Scott,
Are there two separate pilot flames or just two different size flames? I have only one pilot tube to the pilot but I have noticed that after adjusting the small screw behind the control knob it stays on but not high enough to touch the capillary tube. Maybe this is normal in the "pilot on" position.
My manual that came with the coach is no help at all on this.

Absolutely correct- THIS is the place to start. Propane regulators (located on/near the propane tank) DO fail! The are under $30 and easy to replace if defective. They can also be adjusted, using a manometer.

Now, many stoves have a second regulator to further reduce gas pressure. Don't know about your model, but a schematic should show it.

There's just one pilot tube but the flame gets bigger when the oven is turned on.

The obsolete part number for the thermostat valve I need is: 7515P024-60 and it was at one time replaced by part number: W10125661 which is also unavailable.

There's a separate gas regulator under the stove top on the right.

Thanks for the info, if I can find one of those valves...... I will contact you

I never had an oven but in the old days of this forum they were quiet popular as was putting some kind of floor tile in there to help even out the distribution of heat.

Re: Magic Chef Oven flame too large?

Reply #18 – August 16, 2015, 07:33:00 pm

John, you are right about the tile and we use one in our oven in house. Make sure it is a Porcelain tile as they withstand the heat best.
Ruth was told this by friends in Mexico and she tried it and does work.

Oh wow, you really did find that thermostat valve! I don't think I'm gonna buy one though because it costs 1/3 of what a new stove would. I think I could maybe buy a good used stove for a little more than the cost of that new thermostat valve if I shop around. I like my current stove and my ball valve fix works great, I just have to remember it each time. Thanks for finding the part though. I looked all over the internet a few months ago and couldn't find it in stock anywhere at that time.

Just because it shows up on the internet, it does not mean that it is in stock. Googling the part number shoes more hits.

At the time when I was looking for the part I hadn't added the ball valve yet, so I probably would have spent $250 just for one little thermostat valve as opposed to buying a new stove. Now that I added the ball valve fix it seems silly to me to waste that much money on something like that... Funny how my situation changes my spending habits.
