If you’re encountering the FD error code on your GE gas range, it’s typically related to an issue with the meat probe, preventing the oven from operating as expected. Thankfully, there are straightforward troubleshooting steps to help you resolve the problem and get your oven working again.
What is the Meat Probe in a GE Range?
In some GE gas range models, especially the higher-end ones, a meat probe is included to monitor food temperature during cooking. This metal probe, inserted into meat or other dishes, functions as a temperature sensor.
Inside the probe is a thermistor—a device that changes resistance in response to temperature changes. Connected to the oven control board through a wiring harness, the thermistor sends resistance data as food temperature rises, allowing the control board to detect when the target temperature has been reached.
When the probe is at room temperature and disconnected from the oven, its thermistor shows a steady resistance level. If the resistance is outside this normal range, it often signals that the probe is faulty.
Why the FD Error Code Appears
The FD error code generally signals that the oven control board is detecting unusual resistance from the meat probe, suggesting a “probe failure” error. Here are common reasons for the FD code:
- Defective Meat Probe: If the probe is damaged, it may provide incorrect resistance readings outside the standard range of 30 kOhms to 50 kOhms.
- Wiring Harness Issues: Short circuits, damaged insulation, or broken wires in the harness can lead to inaccurate resistance readings.
- Oven Control Board Failure: If both the meat probe and wiring are in good condition, the control board itself could be the cause.
Essential Safety Tips
When performing any appliance maintenance, prioritize safety to prevent injuries or damage. Here are some important precautions:
- Disconnect Power: Always unplug the appliance or switch off the circuit breaker before beginning any work to avoid electric shock.
- Allow Cooling Time: If the oven was recently used, give it time to cool before handling any parts.
- Turn Off Gas Supply: Shut off the gas line to avoid potential leaks while working.
- Avoid Rushing: Take your time to avoid accidental damage or injury; precision is key.
- Work in Adequate Lighting: Ensure you have a well-lit workspace to see and access parts clearly.
- Organize Your Workspace: Keep the area free from clutter, and ensure children and pets are kept away.
- Keep Hands Dry: Don’t work with wet hands or in a damp environment to reduce electrical risks.
- Refer to the User Manual: Check your appliance’s manual for specific safety guidelines related to maintenance.
- Handle Parts Carefully: Avoid using excessive force when handling or removing parts to prevent damage.
- Wear Insulated Gloves: Protect your hands from sharp edges and metal parts.
- Avoid Direct Contact with Exposed Wires: If you need to handle wires, use insulated tools or gloves to prevent electric shock.
- Document Connections: Take photos or make notes of wiring before disconnecting anything, to help with reassembly.
- Use a Multimeter with Caution: If unfamiliar with multimeter testing on live wires, avoid attempting it to prevent short circuits or injury.
How to Troubleshoot an FD Error on a GE Range
1. Test the Meat Probe
- Unplug the range from the power outlet and shut off the gas supply.
- Set a multimeter to resistance mode (Ω).
- Touch the multimeter probes to the outer shaft and the tip of the meat probe connector.
- Check the resistance reading, which should be between 30-50 kOhms at room temperature.
- If the resistance is outside this range, replace the probe. If the probe passes, proceed to the next step.
2. Remove the Lower Oven Door
- Open the oven door fully.
- Locate the hinge locks on each side of the door and lift them up. A small flathead screwdriver may be needed.
- Close the door slowly to a 45-degree angle, letting it rest on the hinges without fully closing.
- Lift the door up and out to unhook it from the hinges and remove it.
3. Locate and Detach the Meat Probe Outlet
- Find the outlet for the meat probe wiring harness on the lower left side of the oven’s interior wall.
- Remove the two Phillips-head screws securing the outlet.
- Detach the outlet from the oven wall.
4. Inspect the Probe Wire Harness
- Examine the meat probe wire harness for insulation damage, disconnected wires, or potential areas where it could touch hot components.
- If any damage is found, replace the harness. Since GE usually does not provide separate meat probe harnesses, you may need a universal replacement that’s compatible with your oven.
5. Replace the Control Board (If Necessary)
- If the probe and wire harness are both in good condition, but the FD error code continues to appear, replace the control board as a final troubleshooting step.
When to Consider Professional Help
While many FD error issues can be resolved with simple troubleshooting, there are times when professional assistance might be the safer or more efficient choice. Here’s when to consider calling an appliance repair expert:
- Persistent FD Error: If the FD error continues even after inspecting or replacing the meat probe and checking the wiring harness, the problem may be linked to the oven control board or another complex internal component. Diagnosing control board issues often requires specialized tools and expertise.
- Lack of Necessary Tools: Some repairs require specific tools, such as multimeters for testing resistance, which may not be on hand. Without the right equipment, it can be challenging to accurately identify and fix the issue.
- Electrical or Gas Concerns: If you’re uncomfortable working with electrical wiring or gas connections, it’s best to consult a professional. Mishandling these components can pose safety risks, especially if you’re unfamiliar with appliance repair.
- Warranty Coverage: If your GE gas range is under warranty, attempting repairs yourself may void the coverage. Check the warranty terms before proceeding; a certified technician may be able to handle the repair at no additional cost.

Conclusion
Wrapping up, dealing with an FD error on your GE gas range might seem tricky, but with these steps, you can often pinpoint and fix the issue yourself. Remember to check each component carefully, from the meat probe to the wiring and control board.
And if things get complicated or you’re unsure, don’t hesitate to call a professional—it’s worth ensuring your range is safe and fully functional. Hopefully, with a little troubleshooting, you’ll have your oven back up and running in no time!
