Frigidaire Oven Error Codes Frigidaire has expanded its product line since then to include a variety of different kitchen appliances, including the Frigidaire oven. The Frigidaire error code system for the oven only has two error codes, F1 and F3. Each code corresponds to a particular kind of malfunction and shows on the display screen as soon as the oven’s memory detects an error. Push the “Clear Off” button to clear the screen and stop the alarm, and reprogram the oven. If the code remains, repairs are necessary.
Frigidaire Oven Error Code Solutions
F1 Error
The F1 code indicates a control failure. Try pressing a key to see if it displays on the screen. If not, the keypad may have shorted and requires replacement. If the keypad is fine, there is perhaps a problem with the internal checksum, or computer data; disconnect the power for 30 seconds and reconnect it. If the code remains, you must replace the electronic oven control, or EOC for short. If the F1 code appears when the oven is running, it means that the oven senses an overheating condition. Use an external thermometer to check the temperature inside the oven. If it is accurate, it means that either the temperature sensor probe or the control relay has malfunctioned. Disconnect the power, and inspect the sensor probe, replacing it if necessary. If the oven is actually overheating, replace the EOC. If the oven is allowed to overheat, the resulting damage will possibly be so extensive that the entire oven may require replacement.
F3 Error
The F3 error code implies an oven probe malfunction. The problem is most likely an open or shorted resistance temperature detector, sensor probe or wiring issue. In fact, if the RTD sensor probe is open, the display may show an F1 error code, thinking there is an overheating problem. Inspect all of the wiring involving the RTD sensor probe, keeping an eye out for shorts and open conditions. If the wiring appears fine, test the RTD resistance at room temperature with a multimeter and compare it to the probe resistance chart on the appliance’s service data sheet. If the reading is off, replace the sensor probe.
| Fault Code | Likely Failure Condition/Cause | Suggested Corrective Action |
F10 F11 F12 F13 | Runaway Temperature. Shorted Keypad. Bad Micro Identification. Bad EEPROM Identification/Checksum error. | 1. (F10 only) Check *RTD Sensor Probe & replace if necessary. If oven is overheating, disconnect power. If oven continues to overheat when the power is reapplied, replace EOC. Severe overheating may require the entire oven to be replaced should damage be extensive. 2. (F11, 12 & 13) Disconnect power, wait 30 seconds and reapply power. 3. (F11, 12 & 13) If fault returns upon power-up, replace EOC. |
F30 F31 | Open probe connection. Shorted Probe connection. | 1. (F30 or F31) Check resistance at room temperature & compare to **RTD Sensor resistance chart. If resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor wiring harness between EOC & Sensor Probe connector. 2. (F30 or F31) Check resistance at room temperature, if less than 500 ohms, replace **RTD Sensor Probe. Check for shorted Sensor Probe harness between EOC & Probe connector. |
F90 F91 F92 F93 F94 | Maximum oven door unlock time exceeded. Maximum oven door unlock attempts exceeded. Maximum oven door open time exceeded. Maximum oven door lock time exceeded. Maximum oven door lock attempts exceeded. | 1. (F90, 91, 92, 93 & 94) Check the wiring between EOC & Lock Motor Micro Switch. 2. (F90, 91, 92, 93 & 94) Replace the Motor Door Latch assembly if necessary. 3. (F90, 91, 92, 93 & 94) Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor Cam. 4. (F90, 91, 92, 93 & 94) Check to see if Lock Motor Coil is open. If open, replace Lock Motor Assembly. 5. (F90, 91, 92, 93 & 94) Lock Motor continuously runs – if Micro Switch is open, replace Lock Motor Assembly. 6. (F92, 93 & 94) Check oven door Light Switch – if open, replace Switch. 7. If all situations above do not solve problem, replace EOC. |
| Code | Cause – Condition | Suggested corrective action |
| F10 | Control has sensed a potential runaway oven condition. Control may have shorted relay, RTD sensor probe may be bad. | Check RTD sensor probe and replace if necessary. If the oven is overheating, disconnect power. If oven continues to overheat when the power is reapplied, replace the EOC. |
| F11 | Shorted key: a key has been detected as pressed ( for a long period ) will be considered a shorted key alarm and will terminate all cooking activity. | Press clear key. If the fault returns, replace the keyboard ( membrane ). If the problem persists, replace the EOC. |
| F13 | Control’s internal checksum may have become corrupted. | Press clear key. Disconnect power, wait 10 seconds and reapply power. If fault returns upon power up, replace the EOC. |
| F15 | Controller self check failed. | Replace the EOC. |
| F30 | Open RTD sensor probe or wiring problem. NOTE: OEC may initially display an F10 thinking a runaway condition exists. | Check wiring in probe circuit for possible open condition. Check RTD resistance at room temperature ( compare to probe resistance chart ). If resistance does not match the chart, replace the RTD sensor probe. Let the oven cool down and restart the function. If the problem persists, replace the EOC. |
| F31 | Shorted sensor probe or wiring problem. | Check wiring in probe circuit for possible open condition. Check RTD resistance at room temperature ( compare to probe resistance chart ). If resistance does not match the chart, replace the RTD sensor probe. Let the oven cool down and restart the function. If the problem persists, replace the EOC. |
| F62 | Missing zero-cross signal | Replace the EOC. |
| F90 | Door motor mechanism failure. The controller does not see the motor rotating. | Press clear key. If clear key does not eliminate problem, turn off power for 30 seconds, then turn on power. Check wiring of lock motor, lock switch and door switch circuits. Unplug the lock motor from the board and apply power ( L1 ) directly to the lock motor. If the motor does not rotate, replace lock motor assembly. Check lock switch for proper operation ( do they open and close, check with ohm meter ). The lock motor may be powered as in above step to open and close lock switch. If the lock switch is defective, replace motor lock assembly. If all above fails to correct the situation, replace the EOC in the event of a motor that does not rotate. |
| F95 | Door motor mechanism failure. The motor does not stop rotating. | Press stop key. Turn off power for 30 seconds then turn power on. If the door lock motor never stops rotating, or if the F95 error comes back again, verify wiring of the motor. if wiring is good, replace the EOC. If the problem persists, replace the motor latch assembly. |
| NOTE: Generally speaking F1X implies a control failure, F3X an oven probe problem, and F9X a latch motor problem. |
