When baking in top oven for any period of time my oven will start beeping with an F4 blinking on the oven temp screen? What is it trying to tell me?

I would try to cancel it out.. and restart it..if it wont clear, slide the stove out and unplug it or trip the breaker in the fuse box..retry..

This can be an issue with the thermocouple in the oven, but it must be acting up to test it and make sure that is the problem.

F4 usually relates to a temperature sensor fault. Meaure the temp sensor at ambient temp and it should measure approx. 1K . If it doesn't, then replace. However, and a big however, I've seen frequent faults such as these where the control board is at fault. The proper procedure is to verify the sensor though first before replacing control board.

HI. an F-2 during a baking cycle is the result of an out of control oven temp that has reached Temperatures above 615F-630F

If this actual over temperature condition occurred, Look for welded relay contacts on bake or broil relays. If this happens, replace oven control (also called clock or ERC).

If no over temperature condition occurred, Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace sensor if found defective.

Remember: Oven control (ERC) measures resistance of sensor circuit , not actual oven temperature.

The temperature sensor is bad. The broil element will work even if the temp sensor is bad but the bake element will not. If you measure the resistance across the contacts on the sensor, it should be around 20 ohms, if it is much higher (1000+), then it is bad and should be replaced. It is just as easy to replace as the elements and looks like a small pencil sized rod in the inside top of the oven. Let me know how this works out for you.

HI thanks for your question. A common problem with gas ovens is that the oven will not get hot enough. and the part that's at fault is the ig niter. replace the ig niter. thanks the appliance doc. please rate my answer. thanks.

you can calibrate you oven try presiing and holding the bake button for 3-5 secs. it should beep and put a 00 in the display. using the temp up or down arrows you should be able to adjust ther temp to a max of 35 degrees + or -. after setting to desird 25 presss start and that setting will be ingrained in the memory forever(or until you change it again)power failure will not effect it either . of that doesnt work gimme the modle and ill ck further

Your husband is correct, kind of. You should not try self clean again until you get the oven repaired. You have a temp sensor going out. I doubt that the oven actually got too hot, most likely the resistor in the sensor is failing as it heats up and giving a false temp reading.Since the lower oven was operating at the time, it is probably the sensor in the lower oven. Don't use it for baking until you get it repaired. It will go out completely and shut down both ovens. You should be able to get a new sensor for around $30 and they are not hard to replace.

The oven won't set your house on fire during clean mode if the cabinets were built with the correct air space and dimensions, but they do get very hot, about 800 degrees F. Most ovens give no trouble during the clean cycle, but if there is any weak components in the electronics system it will show up then. It will give you less trouble over time if you don't use the self clean mode and just manually clean it.

Sears Kenmore Electric Wall OVen, Mod.#9114012192 purchased in 1993. Set oven for 425 degrees, reaches set temperature, stays on about 10 minutes and temp. display goes out and oven starts cooling down. Will not stay on desired temp.to cook. Can you tell me what my problem is? Thanks. Doug.

f4 means it has a shorted oven temp. sensor and will need to be replaced.
