In this article we will discuss most common oven error codes with ovens made by Frigidaire/Elctrolux. I will show you how to diagnose and fix them depending on the fault code.
All Electronic Oven Controls (EOC) have ability for self diagnosis. When an oven fails, usually it will stop working and show on the display an error (fault) code which corresponds to a specific problem. Actually there are only two major parts which, if anyone of them failed, could cause most of error codes. These parts are: Electronic Oven Control (EOC) and oven temperature sensor. Frigidaire used the name RTD sensor or RTD probe, where RTD means “Resistance Temperature Detector” instead of oven temperature sensor.
If the error code shown on your oven display leads to a possible problem with oven temperature sensor, start the troubleshooting from testing the temperature sensor resistance. This part is usually located on the back wall in the upper part of the oven cavity but it can be easy tested from the EOC. Locate the two pins in the plug at the EOC that are connected to the sensor. Measure the resistance between the wires connected to these pins. The normal reading at the room temperature is supposed to be about 1100 Ohms.
If the reading is incorrect, remove the sensor from the oven and check its resistance at the sensor. If the reading at the sensor is the same as reading at the EOC plug, the sensor is defective. If the reading at the sensor is correct, the wiring between the sensor and the control is defective.
If the reading is correct, the EOC would need to be replaced.
The vast majority of oven controls, used by different manufacturers, consists of two separate parts – the electronic control board and the user interface device (keypad or touchpad). Frigidaire incorporated keypad into the electronic control board for most of the models and used just a faceplate or overlay which is adhered to electronic control board. It can be easily determined by the model number, usually located on the frame behind the bottom drawer or on the oven door frame. Use the “Search by the model number” link bellow to see if your range has a such part. If it does, I would recommend to order both of them because it’s very hard to remove faceplate and reattach it without damaging the part.
NOTE: Before you will proceed with any tests, disconnect power for at least a minute. If fault returns when power is reconnected, continue the troubleshooting. If the oven problem is intermittent you must do the tests when the oven is malfunctioning.
Older products will show only two digits F-codes, but on ranges manufactured beginning in 2004 many of EOC’s will have expanded three digit fault codes. There are probably over 50 different error codes but in this article we will review only the most common ones.
F1 or F10 – Runaway temperature.
If these error codes shown while the oven is in day time mode, the EOC would need to be replaced. Otherwise check the oven temperature sensor (RTD sensor) as described earlier and replace if necessary.
Most of the EOCs incorporated power relays among all other components while some of ovens use a separate power relay board to simplify design and lower cost of production. You can determine it by visual EOC inspection and/or by the wiring diagram for your oven (if it is available). If there are some relays on it, replace the EOC. If there are no relays on the EOC, check the parts list (Search by the Model number) for the relay or power board. If there is a such part, replace it. I’ll be glad to help you if any problems with the diagnostic. Just leave a comment on the bottom of the page. In such situation I’ll need the complete model number of the oven.
F11 – Shorted keypad.
If fault returns after reconnecting power, replace the EOC.
F3 or F30 – Open/shorted sensor (RTD probe) connection.
Check the temperature sensor resistance as described previously. If the reading is incorrect and the wires and plugs between the sensor and the EOC are good, replace the temperature sensor (RTD probe). If the sensor and wiring are good, the EOC would need to be replaced.
F4 or F31 – Shorted sensor (RTD probe) connection.
Check the temperature sensor resistance as described previously. If the reading is incorrect and the wires and plugs between the sensor and the EOC are good, replace the temperature sensor (RTD probe). If the sensor and wiring are good, replace the EOC.
F8, F9 or F90 – Lock motor switches improperly positioned.
Check the lock motor and the switches for continuity. If there is something wrong, replace the door lock assembly. Check the wiring between the EOC and the lock motor and switches. If the lock motor, switches and wiring are good, the EOC would need to be replaced.
