My oven will not heat up to temperature

The self cleaning features only serves to keep manufacturers in steady sales of parts. Quite simply the oven can only take those temperatures a few times until they break. The heat burns out elements, damages fans, door locks and worst of all damages control boards which are not far enough from the heat source. It sounds like your control board is fried. Try turning it of at the breaker for 15 minutes by way of a reset.

Never use the self cleaning feature as stated here

If you have been using the self clean feature, you have probably burned out or damaged the connections to the fan and the convection fan element or thermistor. NEVER EVER use the self clean feature.

About 6 times a week we see 'Self Clean' cycles that break ovens. Try removing the mains plug or turning off the breaker for an hour. If that doesn't fix it, you will need a service call on you mystery make appliance. It could be the thermostat burnt out or the control board frazzled.

Self Clean oven temperature is about 880 degrees Fahrenheit.
Self-Clean Ovens
The oven is cleaned by heat, at temperatures above normal cooking temperatures. During the cleaning cycle the oven is heated to about 880 degrees Fahrenheit (471° C.). At this temperature, food soils inside the oven decompose, leaving behind a small amount of ash.

Self cleaning ovens clean at a temperature exceeding 900 °F. The doors get way too hot to touch until they cool, but tg h ef cabinet sides and back are equipped with additional thicknesses of special high-temperature insulation. This is required for the oven to pass the clearances requirements.

If your concerned, the minimum required clearances (the required separation from the sides and back of the oven cabinet to the surrounding combustible construction) is stated in inches. Also the minimum clearance over the cooktop).

This information is specified on the listing label. The label is required to be visible after installation, that is, under the cooktop (if the cooktop cover is removable), or (more commonly), on inside the cabinet visible when you open the bottom drawer.

Ideally your oven has a 0" clearance requirement, but there may be a separation of x inches. This space must remain clear to prevent overheating combustible construction.

Never run a self cleaning cycle whilrvyour gone of sleeping. While generally safe, the danger of a fire is expediently higher during the cleaning cycle. (It may also set off your smoke alarm as the food particles burn into ash).

You may have a blown thermal fuse in series with the heating elements. If the oven exceeded the maximum allowable temperature during self-clean, the fuse will open. See this discussion:
Oven Failure After Self Clean and F1 Errors

the preheat light wont go off on my oven, and its not really hot. my oven light is on as well ,how do I turn off the preheat light

Hi, F2 error code on the Amana Oven means "Oven too hot" You have to replace Oven temperature sensor to fix it.
F3 error code means "Open or shorted oven temperature sensor". Yo also have to replace Oven temperature sensor to fix it.

Summarily, both code has to do with the temperature sensor which you need to replace...

Don't open or try to open the oven door, until it has cooled down completely. The oven heats to a very hot temperature, usually 800 to 900 degrees. The door locks itself once it gets to a certain temperature, and will not allow the door to be opened until it cools below a certain temperature. On some units, this can take hours to cool down enough to unlock. If you try to force it before the cooldown is complete, it usually results in a repair call. If it still will not unlock when it is cool, turn your power to the oven off for 20 minutes, then turn on and reset your oven controls. Sometimes you have to put the oven back into the self-cleaning cycle, and then cancel it immediately to cycle the oven door lock. If it still won't unlock, call a repair company out to service this. Good Luck, Appliance Specialists

There is nothing wrong with cleaning a self-cleaning oven. Now, I don't have experience with your speicific oven, but I do have experience with other self-cleaning ovens. The self-clean function simply heats the oven up really hot. The actual temperature varies but the oven will get hotter than the hottest temperature setting. What happens is that when it get that hot it actually burns up spilled food and crumbs. sometimes in mine I even see small flames. The oven usually requires you to lock it as well since the temperature will be so high. Eventually you have to clean out the burnt "ashes" which are basically the stuff you get on food if you burn it. So the answer to what happens if you clean the oven is that you get a clean oven, nothing else. It won't hurt the oven at all. As a matter of fact even if you use the self-cleaning feature you will eventually have to clean out the "burnt crumbs" and such by hand anyway. So self-cleaning oven are designed to be cleaned by hand as well. And you won't hurt it by doing so even if you did it every day.
