DIY Appliance Repair Series | FGGH3047VF Frigidaire 30" Gas Range | Error Codes

True to form, Frigidaire introduced the first oven with air fry. The feature aside, this oven is deserving of some high praise because it’s a solid unit. People love the fact that the oven temps are accurate and it regulates well. 

Not to rain on your parade, but as the unit gets used daily, problems do come up. Fortunately, they’re not deal-breakers that force you to push the range to the curb.  

Most of the issues arise from not cleaning the unit periodically. The burners and burner heads need cleaning regardless of their appearance. Heck, put them in the dishwasher if you don’t feel like cleaning them by hand. But clean them often. A gas range needs a little TLC on a regular basis. 

As for the oven, it needs cleaning, too. If you want to use the self-clean function, great! But after that finishes, be sure to follow up with some manual cleaning. As good as the self-clean function is, it can’t remove everything that must go. 

Ok, so enough about cleaning. I felt I should mention it because if you keep your appliances clean, especially the range, it will pay you back in spades with trouble free performance for years to come. Let’s get down to the reason we’re here, shall we? 

By the way, I understand this model can get confusing when troubleshooting. If that’s ever the case and you need some help, set up an appointment with us. We’ll help you through. 

FGGH3047VF Error Codes

3. If the wiring harness is good, replace the touch panel.
4. If the problem persists, replace the control assembly (UIB and touch panel).

F25 F27 The communication between the over user interface and the oven relay board cannot be initiated.

1. Disconnect power to the unit, wait 30 seconds, then reapply power.
2. If fault returns, verify connection between the oven user interface board (MACS1 or MACS2 connector) and the oven relay board (connector J3 or J4).
3. If fault persists, replace the relay board.
4. If fault persists, replace the control assembly (UIB and touch panel).

F28 F29 The communication between the over user interface and the touch panel cannot be initiated.

1. Disconnect power to the unit, wait 30 seconds, then reapply power.
2. If fault returns, verify the touch panel is connected (verify harness going to I2C1 or I2C2 connector) and is getting power from the oven user interface. 
3. If fault persists, replace the control assembly (UIB and touch panel).

F30 Open oven temperature sensor (RTD)

F31 Shorted oven temperature probe (RTD)

1. Check probe circuit wiring for possible open or short conditions.
2. Verify RTD resistance at room temperature (compare to probe resistance chart). 
3. If resistance does not match the chart, replace the RTD probe. If the problem persists, replace the oven relay board.

RTD Resistance Chart:

F33 Meat probe temperature sensor shorted or too hot.

1. The error is triggered if the meat probe sees a temperature in excess of 392°F. Make sure the meat probe was not used in such a way that it could have seen such temperature. If the tip of the probe is not inserted in the meat it will see the cavity temperature, which can be higher than 392°F (depending on the setpoint) and trigger the alarm.
2. When the meat probe is connected to the socket inside the oven cavity, if the meat probe is not fully inserted into the socket it may short the contacts and cause the error. Make sure the probe is inserted as much as it can.
3. Verify meat probe resistance at room temperature. Compared to the meat probe resistance chart. If the meat probe does not match the chart, replace it.
4. If the above steps failed to correct the problem, replace the oven relay board.

F50 A/D Out of Range: the oven relay board is unable to read the status of the switches (door, MDL).

1. Check to ensure that the connections between the door switch, MDL and temp probes are properly connected. This includes all splices and junctions. 
2. If the above step failed to correct the problem, replace the oven relay board.

F90 Motor Door Lock mechanism failure. The oven control does not see the Motor Door Lock running.

1. Disconnect power to the unit, wait 30 seconds, then reapply power. Try again to make the door lock or unlock (ex: initiate a Lockout or a Clean cycle).
2. Check if the Lock Motor is running or not. If it is not running, test the wiring between the Lock Motor and the oven relay board. If the wiring is good, check if there is 120VAC at the motor when it is expected to run to see if the failure originates from a bad motor (120VAC present but not turning) or a problem with the relay board (J20 pin 10 on the oven relay board is the output to the Lock Motor). The Lock Motor can also be tested by applying 120VAC directly to the motor (unplug it from the relay board first). If the Lock Motor does not run when 120VAC is applied replace the Lock Motor Assembly. If it is the relay board that does not provide 120VAC to the Lock Motor replace the oven relay board.
3. If the Lock Motor is running but the oven control cannot find the locked or unlocked position (ex: motor turns continuously until F90 fault code is generated) the Lock Switch needs to be verified. Check wiring between Lock Switch and oven relay board. Verify with ohmmeter if the switch makes contact properly (verify continuity with ohmmeter when the switch is pressed). If the Lock Switch is defective replace the Motor Lock Assembly.
4. If all above steps failed to correct the situation, replace the oven relay board.

F95 Motor Door Lock mechanism failure. The Motor Door Lock does not stop running or the Lock Switch sends an invalid signal.

1. The problem can be caused by a faulty Lock Switch or by a defective oven relay board. If the Motor Door Lock is always running (as if the relay controlling it is stuck closed) replace the oven relay board.
2. If the motor is not always running, replace the Motor Lock Assembly.

F96 The oven door has been detected open during a Self Clean cycle.

1. This error occurs if the door switch has lost its contact during a Self Clean cycle. Make sure the oven door closes well and fully presses on the door switch plunger when the door is locked, and no one attempts to pull on the oven door during the Self Clean cycle.
2. Test continuity of wiring between the door switch and the oven relay board, make sure the door switch is well connected. With an ohmmeter, verify the switch is closed when the plunger is pressed. If the door switch is found to be defective replace the door switch.
3. If the switch and wiring are good and the problem persists, replace the oven relay board.

F97 MDL invalid state. Relay board (OVC) sensed the motor door lock in a state it should not be in according to the user interface board.

1. Disconnect power to the unit, wait 30 seconds, then reapply power.
2. If fault persists, replace the motor door lock.
3. If fault persists, replace the oven relay board.
