Disclaimer: The error code information provided in this article is based on general service manuals and may not apply to your specific appliance model. While we strive to offer helpful advice for DIY appliance repairs, variations in models and configurations can lead to differences in troubleshooting steps, error codes and part replacements. For the most accurate guidance, we strongly recommend consulting the technical sheet for your specific appliance model.

What does the F9 error mean?

The F9 fault code typically indicates an issue with the lock-sensing switch during the high-heat self-cleaning mode or regular cooking cycle. Specifically, it means the door latch is showing unlocked when it should be latched while the oven temperature is above approximately 915°F (the runaway set point). Or, the door latch may be showing that it’s locked during a normal cooking cycle when the temperature is at a regular temperature.

There are two potential causes:

• The door lock motor is attempting to activate the lock, but the latch sensor is falsely signaling that it’s already in the locked position.
• The latch sensor is mistakenly switching to the unlock state when it should show locked due to a high runaway temperature.

Safety tips

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by preventing any risk of electric shock.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• Shut off the gas supply to prevent any gas leaks while you work.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.
• Consider wearing safety glasses and/or a dust mask when working with chemicals, dust or a large amount of debris to prevent irritation or injury.

How to troubleshoot the F9 error code

Follow these steps to troubleshoot & resolve an F9 fault code on your gas GE range.

Step 1: Inspect the door latch assembly and switches

Since the F9 pertains to the oven door latch, our first focus should be thoroughly inspecting and testing the latch parts.

1. Turn off the range and unplug it from the outlet.
2. Shut off the gas supply to the range.
3. Check the door latch hook and slots for any damage or binding that could prevent it from locking. Look for any obstructions around the latch that may block or restrict latch movement. If you find any debris, clean it out.
4. Activate the lock/unlock mechanism through a full cycle and watch it as you do this. Listen for sounds or signs of sticking, grinding, or binding.
5. Detach the oven door.
6. Set a multimeter to the continuity setting.
7. Use the multimeter probes to check the electrical continuity of the latch switches and motor windings.
8. Check the meter reading during each test. The motor winding resistance should be about 3 kΩ. Locked switch contacts should have continuity (closed circuit when locked). Unlocked switch contacts should have no continuity (open circuit when locked).

If you get out-of-specification readings during any test, replace the affected part(s) with new OEM parts.

Step 2: Reset the oven control board

After you’ve checked the door latch assembly, you can try resetting the oven control board.

1. Shut off power to range for at least 5 minutes at the breaker panel or fuse box. This should clear any random error codes from the board.
2. Restore power to the range and test the self-clean mode again. If the F9 fault code persists and all other parts are functional, then the control board is likely the cause and should be replaced.
