I have an older gas oven/stove top and would like to disconnect the feature that turns oven off after 12 hours

If you have the older type stove with the oven knob that has the temperature setting around the outside of the knob, then that part could be bad. It is called a thermostat. That part usually comes with sensor attached. The sensor is the long skinny looking tube that goes through a hole and into the oven.
If you have the newer type electronic stove where you program in the temperature you want, the electronic circuit board could be bad. But the electronic stoves have a over temperature protection built into the circuit board, so that would have engaged, shutting down the stove.
Either way, it is a potential fire hazard and needs to be addressed.

Hi,
That sounds like you have too high of gas pressure which keeps the oven gas valve from opening...turning on the burners lowers the gas pressure enough to allow the gas valve to open. this is a saftey feature on many gas valves.
To stop that you will need to install a gas pressure regulator which will hold back the gas pressure so the valve can open.

Here is a tip that I wrote about regulators and them failing on the low side, but it will give you and idea what I am talking about and what you need to install in the line to your range.

can you hear gas coming in when you turn the know to "ligth" if not the you may have either a bad gas valve or the safety feature has detected something wrong, and has shut the gas off to the oven. first determine if you do indeed have gas., how does the oven light, is it pilot lit, or does it have a glow plug, if its pilot lit, make sure the pilot is running. if its a glow plug, you should be able to see it glow when you turn the oven on, if its not glowing it has to be replaced (or maybe the wiring has gone bad). either way that's where to start.

Most of these new fangled gas stove feature a silicone carbide ignitor to light the oven. Older stoves used a standing pilot light. As silicone carbide ignitor age a little they tend to get weak and fail to open the gas safety vave sufficiently enough for ignition. Take a look

Hello, I found this info on the manual for your oven:

12-hour automatic cancel This safety feature prevents oven from continuing to operate if it has been left on for over 12 hours. If a cooking function continues longer than 12 hours without any options on oven control being touched, this feature turns oven off. Any time an option is touched, 12-hour automatic cancel is reset.

If you want to print up your own owner's manual, here is the Amana link. Just type in your model # and then click on the link to read it or print it up

The pilot light must be lit and stay lit before you will have any propane coming into the oven. This is a safety feature.

For safety purposes call gas technician to check your gas pipe. If stove turn off supposed not to smell gas.

do you see a bright glow in the oven area when the oven is turned on it will take 20 secs or so..If not your ignator maybe bad no gas will flow into the oven unless the ignt. is good

disconnect the wires going to the oven ignitor,turn the unit on see if its trips.if so the ignitor is shorted if not then disconnect the wires that go to the coil of the gas valve and do the same.i think either one of these is your problem.also if theres a fan in the oven do the same.

The control is automatically set to turn off the oven after 12 hours baking or 3 hours broiling should you forget and leave the oven on. If you want to remvoe this feature do the following steps: 1. Press and hold, at the same time, the BAKE and BROIL buttons for 3 seconds, until the display shows "SF". 2. Press the DELAY START TIME button. The display shows "12Shdn" for 12 hour shut off. Press the DELAY START TIME button again. The display will show "no Shdn" for no shut off. 3. Press the START button.
