Vintage Magic Chef Oven Operation Primer

I have a 66 Tradewind with the original Magic Chef range/oven. I have had it for 2 years and never have used the oven- I tried one time to light it but I was not successful. My daughter went camping with us and wanted to cook something in the oven. I had to tell her that the oven did not work, so she will need to go to plan B.

I looked at the owners manual and tried to start the oven up, but I was not able to. Part of the problem was the instructions in the manual. The section pertaining to lighting of the constant pilot and the adjustment of the pilot is partially wrong. The words in the manual state "Open pilot valve (A), light constant pilot (B) with match and adjust pilot valve (A) by reducing flame on constant pilot (B) until yellow tip disappears." The problem is that pilot valve (A) is a shutoff valve. It can not be used to adjust the flame. The adjustment screw is below the shield at the back of the oven and is accessed through a hole in the shield. See photos below.

Basically, I was able to get the oven working by taking the gas jets apart, cleaning them out using solvent and compressed air, and then lighting them and adjusting the flame using the adjustment screws. The sequence and location of valves and adjustment screws can be viewed on the following link.

I hope this helps other folks get their magic chef ovens to operate.

Which pilot lights? There are 2 pilots- the constant pilot and the heater pilot. The constant pilot stays on all the time and is used to light the heater pilot. The heater pilot heats the thermocouple which then allows the main burner assembly to operate. You may want to look at the pictures I put in the link above.

They are both working. I'm not sure what your photos are showing. I will go take some pics of mine.

Thank for the help

I turn the heat cont knob on and only see one flame. It lights right up. Am I doing something wrong?

The heater pilot "heats" up the thermocouple (tc) which sends an electrical signal to the main gas valve saying that it is safe to open. Then the heater pilot flame ignites the main gas valve flow. Sounds like you may need a new thermocouple. Look at figure 7b from the owners manual. Also look at the photos below showing the constant pilot tube- it is the larger of the pilot tubes that has a couple of tiny holes at the end that you can not see. The heater pilot tube is smaller and has 3 holes plus a longitudnal slot. Take a phillips screwdriver and remove the screw holding the thermocouple in. Then take a small wrench and remove the other end of the thermocouple at the back wall of the oven. Take the tc to a hardware store and get a matching type. They are cheap because most older gas appliances use them. Once you replace the tc you should hear the main gas valve open and the heater pilot should ignite the main burner. If the main burner flame is not strong enough you may need to clean the main concentric gas jet (see photos) or adjust the jet.

In looking at your photo, I don't see a flame coming from the constant pilot. I assume this means that you had to light the heater pilot with a match or lighter. The purpose of the constant pilot is that you light it when you are using the stove and then it ignites the heater flame when you turn the oven on. For the constant pilot to come on you must open a valve and then light the pilot. The first photo below shows the constant pilot while the second photo shows both pilot flames. However this has nothing to do with the main burner not coming on. This appears to be a thermocouple problem.

Great Info

Hey Dan

Thanks for the great info. It is very helpful. I was to warm in inside my AS to to get any work done today. I going to check things out in the morning. You are right I did light the pilot with a match. I am planning pulling it apart as you suggested. I let you know how things work out.

Thanks for the post: I have a '64 Magic chef, and have gotten the burners to work but not the oven. There is some gas coming out of the pilot under the oven but it won't stay lit, maybe the thermocouple is shot? The pilot on the rangetop won't light at all, but the burners work. I thought perhaps the PO (original owner) may have turned off the range pilot to save gas, and wondered if there is a way to do that, maybe cranking all the way down on a pilot adjustment? Is the manual you mention part of the AS Owner's manual? I'll have to get one. Is it possible to replace the thermocouple in the under-range pilot? Do you think it might be that the pilot is gummed up, and there is a way to take it out and clean it the way you described?

Thanks

Peter

Update: the range works now, and with the instructions, figured out how the range worked. The primary pilot was getting gas but was sputtering. When I got it to work, I turned on the range and the secondary pilot lit, and then the range. Once it's on, the oven worked prefectly, repeatedly. I took the primary pilot tube out of the oven valve and alternated solvent and compressed air through it, dried it and re lit it- pilot works. We're making lasagne in it next weekend when we go camping! Thanks for all your help!

thanks for this thread..my 66 Overlander oven has the same problem
But where is ha gas valve you show in the photos? Behind the oven? I may be missing it, and that could be my main problem.

Mine is under the burner cover on the top. The top lifts off and you will see the valve.
