Re: oven heats up then switches off
There is an overheat stat in the oven which turns it off if overheating. the causes are several.
1 - oven thermostat is faulty and oven is reachingf too high a temp.
2 - there is a second fan in the casing to keep the casing cool.
3 - this second fan is turned on by a fan start stat which may be faulty and is not starting the cooling fan
4 - the overheat stat itself is faulty.
it is a bit difficult to narrow it down from afar. get back to me if you want

When you go into self cleaning both of your burner element peak at there max temperature, well above 500 degrees F.
1.) Oven Element - Over time the elements will fail. Turn the upper element on. Inspect for sparking where there may be a crack in the element. Turn the upper element off, inspect for any cracks.
If there are no cracks then you lower element is fine.
2.) Each of your ovens have a independent thermocouple. Both may have failed due to the extreme heat. Oven thermocouples will fail on older units.
3.) Lets go to the source. You have what is called a infinite switch in your oven. This switch controls your oven temperature. If this switch fails then your oven will not work.
Ok, lets assume you or a friend are good with tools. With a multi-meter set to the lowest Ohms, In the back of your oven there is a sheet metal cover. Remover the cover, disconnect the two contacts on each thermocouple, and Ohm them out. (Power Off at your breaker box first) You should get a reading of '0' Ohms, anything else the thermal couples are bad.
But, I tend to believe, You have a bad infinity switch. You can also Ohm this out as above with a reading of '0' Ohms.
This component is about $35.00 USD.
If I were still working for Sears Home Services I would charge you $350.00- $450.00 for this service call. Send me your model number and let me see what you have. firstname.lastname@example.org.
Hello- This is a brand new model, but it works the same as the rest. Heat is produced by the elements. The fan has an element that glows when heating the air. --Convection oven glass gets hotter than normal fanless models.-- This is all normal operation of the oven. To ensure full life of oven, avoid using the 'self-clean' feature. Techs call this the 'self-destruct' cycle. Please reply to this post if info is helpful- have more if needed- Thanks- Ed
You may have one leg of power that is out. First turn off the breakers, then back on. Check it to see if it is better. Then check the wiring from the receptacle, to the plug, to the back of the oven. Look inside the back of it and see if you see any fuses. They could be blown as well. If you are getting some heat (red) then it is an indication of a wiring or fuse problem. Now, one last thought here, if you turn it to high heat does it heat up faster? This one lead it to be in the control switch. Let me know how you do.
Hi, If your electric oven is not heating then you probably have a bad heating element in your oven. This is not that hard to fix yourself... Check out this tip that I wrote about the Oven not heating problem..
1. Faulty thermostat. 2. Faulty thermal cut out switch. (controls power to cooling fan). 3. Faulty cooling fan (not fan inside oven).
Test thermostat by setting thermostat to low temperature like 60 oC. If oven gets much hotter then its a faulty thermostat. To test cooling fan and thermal switch take oven out and remove top or rear panels to expose components. When oven gets hot the cooling fan should turn on. If it doesn't then check to see if there is a mains voltage present. If mains current exist but fan is not turning then replace fan. If mains voltage is not present then its the thermal switch.
Pull the bottom of the oven off. You will see 2 to 4 screws that hold the panel on. The ignitor is under there. Look at the ignitor carefully for breaks. I say carefully as the ignitor is very easy to break.
We have the same problem with our oven, AEG B2190-1.It started on on Christmas day[worst day of year]gets up to temperature after 10-15 minutes cuts out everything switches off until the oven has cooled down, The oven is only 18 months old. We have been told that it is a thermostat problem.
