Question about Ovens

1 Answer

My Magic Chef gas oven is flashing F3 and beeping. The model # is CGR3740ADW. I think that means a bad sensor, but how do I figure out which sensor and how to replace it? If I had some diagrams or something I could probably figure it out.

There is only one sensor. Look inside the oven on the top right or left rear. The sensor is about 3 inches long,metal and about the size of a thin pencil. It will be held in by one or 2 screws. Unplug the range. Remove the sensor and disconnect the wires. Use a volt meter set for ohms. It should read 1100 ohms plus or minus 50 ohms. If it reads more or less replace it.
If you have no meter just replace the sensor. It is bad if the control says it is bad.

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.

F2 flashes and beeps. What does it mean?


F2 usually means that for an unknown reason, the oven temperature has exceeded a preset threshold.
Check the sensor bulb in your oven, it could be bad or your thermostat is not working properly.

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 cleaned my oven. When the cleaning was finished the oven started beeping with an "F3" message... Please help!


Hi


Thanks for using FixYa. Error F3 in your range/oven means oven temperature sensor circuit failure. To resolve this issue you’ll have to check the oven temp. sensor circuit if the reading is more then 1100ohms then it should be replaced however, if the rating is fine then it is the Electronic Range Control (ERC) that has gone bad & should be replaced. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

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.

Contune to beep F-1 flashes


f-1 codes are usually a temperature issue. you should try ohm'ing out the temperature probe you should have about 1260 ohms. if you are off by 40 ohms then replace the temperature probe. if it is close then you may have a bad control.
