Question about Ovens

1 Answer

Heat Sensor Could you tell me what causes a heat sensor on an oven to go out. I have a Magic Chef Model #CER3540AAA and recently got the F3 error code. My landlord is refusing to repair it and saying that it happened due to something I did. Could you please just give me a list of reasons on why it would go out. Thanks!

Your landlord just doesn't want to pay for it, regardless of how the failure happened. Any kind of sensor except a thremocouple is prone to failure because of the high heat to which it is exposed. Since handling the tiny output of a thermocouple requires a more sophisticated circuit to derive temperature from its surroundings, the sensor is likely a special kind of resistor called a thermistor designed to change its resistance value in concert with the changes to which it is exposed and these are a lot more likely to fail than the thermocouple.   
I don't know your range but the sensor itself is probably not expensive but I don't know how much disassembly is needed to replace it.
Calling a dealer with a service department could get you a ballpark number on the total cost related to that specific model.
The part that seems to be what you need for that model can be viewed here:

    The link still works but the data I entered, namely your model number ( CER3540AAA ) and the word 
    ' sensor  ' have expired so I cannot supply you with an immediate link, you will have to make those entries on the page that comes up.
    If you notice, it displays a warning that the session has expired.


    Try it again with those entries -

Service Code F-3


Hello,
The error code's F3&F4 are codes that mean their is a problem with the oven tempature sensor and that sensor is uncappable of telling the control board what the temp. is in the oven. This is what the sensor looks like,oldtech2332_20.jpgTo check the sensor,unplug it and place meter leads into the white plastic plug at the end and check for between 1060-1100 ohms of resistiance when its good.

The F3 error code means that the sensor is shorted so if it indeed is shorted the meter reading will show ZERO ohms resistiance instead of the 1060-1100 of a good one.

The F4 error code is for sensor that has a open circuit,so instead of the 1060-1100 of a good it the display on the meter will show infinate resistiance ( the meter display will not change)

If on either the F3/F4 error code if at room tempature when checking the oven sensor if the display shows anything other that 1060-1100 ohms the sensor is going to be the problem and needs to be replaced.

I have a magic chef electric wall oven and it flashes an error code of F3 when I try to bake something. How do I fix it and what does it mean?


The F3 code means that the temperature sensor in the oven is not giving the signal to the oven control. This could be the result of a problem with the wiring or the wire harness between the control board and the sensor or indicate that the sensor itself has failed.

To identify the correct parts, you need to provide your oven model number. Try here: http://www.partselect.com/Magic-Chef-Parts.htm . There are other sources for parts.

I hope this helps. If you add a comment with the model number, I'll be glad to give you more specific information for your wall oven.

F3 f4 gaas oven when preheated these numbers appear it beeps and shuts off


Hi, replace the oven temperature sensor if "F2," "F3" or "F4" is displayed. "F2" indicates the oven temperature is too hot and the oven temperature sensor is suspect. "F3" or "F4" indicates the oven temperature sensor or shorted or open.

I have a magic chef range. I ran the self cleaning on the range. Now when trying to use the oven I get a F1 and a F3 code. I unplugged it for a while to reset and still have the same problem.


F1 Defective touch pad or clock (ERC) Replace touch pad or clock (ERC). Touch pad is a more common problem. Refer to F1 test at the top of this page for more information. F3 or F4 Shorted or open oven temperature sensor (RTD) Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.

What does blinking beeping F2 mean?


Hello there"
The F 2 error that you are getting is telling you that the temperature sensor is going bad and needs to be replaced the temperature sensor is what senses the ovens temperature say you have it set for 350 when it is at 350 the sensor tells the oven to stop heating up and when it gets to a certain temp below that value it will make the oven heat up again
it looks like this

Hi jmhostetler9,

This F3 that keeps flashing on your oven is caused by a shorted or open oven temperature sensor (RTD). To fix this problem check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.You may contact Sears for the replacement part at 1-800-252-1698; M-F 6:30 AM-10:30 PM - Sat 7:00 AM-9:30 PM - Sun 7:30 AM-9:30 PM - All times Central. Just get your model # ready when you call.

Hope this helps.

Thank you for using FixYa.

I have a majic chef oven, when i turn it on it beeps and flashes


Self clean on some older models can cause some issues. F-3 is a sensor error. This could have been damaged by high heat or in some cases if the sensor is ok, the control doesn't know it's there.
