GE Oven Error Codes: Complete List with Fixes

GE ovens and ranges use an Electronic Range Control (ERC) board to manage all cooking functions — bake, broil, convection, self-clean, and probe cooking. When the ERC detects a component failure, sensor anomaly, or safety violation, it halts the operation and displays an F-code (fault code) on the display panel. GE uses an F-number system where the number corresponds to a specific failure category. This guide covers every GE oven error code with real part numbers, diagnostic procedures, and repair costs.

How GE Oven Error Codes Work

GE ovens display error codes in the F-number format (F0 through F9, plus FD). The ERC board is the brain of the oven — it receives input from the keypanel, reads temperature from the oven sensor (RTD probe), controls the heating elements or gas valves via relays, and manages the door lock motor for self-clean cycles.

Important safety note: Unlike washers and dryers, oven error codes can indicate immediate fire or safety hazards. F2 (over-temperature) and F4 (shorted sensor) can both result in uncontrolled heating. If you see either code, disconnect power at the breaker immediately.

GE SmartHQ diagnostics (WiFi models): Newer GE ranges with WiFi Connect can push error codes and cooking history to the SmartHQ app. Open the app, select your range, and tap "Appliance Health" for stored fault codes and temperature sensor logs.

Service Mode entry: On most GE ranges, simultaneously press and hold the Bake and Broil buttons for 3 seconds. The display enters diagnostic mode. Use the temperature UP/DOWN arrows to scroll through stored error codes. Press the self-clean button to run individual relay tests.

Basic reset procedure:

1. Turn off power at the breaker for 2 minutes (GE ERC boards require longer resets than other appliances).
2. Restore power. If the code does not return, the fault was transient.
3. If the code returns immediately on power-up, the component has failed and needs replacement.

F0 — Stuck Keypanel

The F0 code means the ERC board detects a continuously pressed key on the control panel membrane. The board cannot determine which function the user intends, so it locks out all operations.

Common causes:

• Keypanel membrane delamination from steam or spill exposure — stovetop boil-overs send moisture up behind the panel
• Grease buildup around button edges creating phantom presses
• Ribbon cable connector between keypanel and ERC corroded or loose
• ERC board input matrix fault (rare)

How to fix:

1. Power cycle at the breaker for 2 minutes. If F0 clears, moisture was likely the cause. Run the oven at 200 degrees F for 30 minutes to dry out the keypanel area before replacing parts.
2. Press each button individually to find the stuck key. Pay attention to buttons near the front edge that are most exposed to steam.
3. Isolate the fault: Remove the back panel to access the ERC. Disconnect the keypanel ribbon cable from the ERC board. Restore power. If F0 clears with the keypanel disconnected, the keypanel membrane (part WB27X32103) is at fault. If F0 persists, the ERC board (WB27X31900) has failed.
4. Clean the ribbon cable connector before replacing parts — corrosion on the pins mimics a stuck key.

Part cost: Keypanel overlay (WB27X32103) costs $50–$100. Ribbon cable (WB27X25555) costs $15–$30. ERC board (WB27X31900) costs $150–$300. Professional repair runs $180–$400.

F1 — ERC / Keypanel Needs Replacement

The F1 code indicates the ERC has detected an internal keypanel communication fault that it cannot resolve. Unlike F0 (which identifies a specific stuck key), F1 means the ERC cannot identify which key or function is failing.

Common causes:

• Keypanel membrane failure — multiple key areas have degraded
• ERC board communication circuit failure
• Ribbon cable damage (cuts, corrosion, bent pins)
• Both F0 and F1 in history indicates the ERC board itself is failing

How to fix:

1. Power cycle at the breaker for 2 minutes.
2. Disconnect the keypanel ribbon cable from the ERC. If F1 clears with the keypanel disconnected, replace the keypanel (WB27X32103). If F1 persists, the ERC board (WB27X31900) needs replacement.
3. If both F0 and F1 appear in the code history, start with the ERC board — the keypanel scanning circuit on the board has failed, and a new keypanel will not fix it.

Part cost: Keypanel (WB27X32103) costs $50–$100. ERC board (WB27X31900) costs $150–$300. Professional repair runs $200–$400.

F2 — Oven Over-Temperature

The F2 code is a critical safety alert — the oven temperature has exceeded the maximum safe threshold (typically 650 degrees F during normal baking or 1,000 degrees F during self-clean). The ERC immediately cuts power to the heating elements.

Common causes:

• Oven temperature sensor (RTD probe) failure — reading falsely low, causing the ERC to keep heating (part WB21X5301)
• Bake or broil relay on the ERC stuck closed — the relay welded shut from arcing, continuously energizing the heating element
• Heating element grounded to the oven cavity (sending current to ground instead of through the element circuit)
• Runaway self-clean cycle (sensor failure during the 900+ degree F cleaning cycle)

How to fix:

1. Cancel any active cycle and open the oven door to ventilate heat.
2. Disconnect power at the breaker immediately. F2 is a fire safety code — do not attempt to continue using the oven.
3. Test the oven sensor: After the oven cools, access the sensor probe at the top-rear of the oven cavity. Disconnect the sensor connector at the back of the range. Measure resistance: a healthy GE oven sensor reads approximately 1,080 ohms at 70 degrees F, rising to approximately 1,600 ohms at 350 degrees F. If resistance reads open (infinite) or very low (under 500 ohms), the sensor has failed.
4. Check the relay: If the sensor tests normal, the bake or broil relay on the ERC may be stuck closed. With the oven off and power disconnected, you can sometimes hear a stuck relay by shaking the ERC board gently (a loose rattle indicates freed relay contacts — but it will stick again). Replace the ERC board.

Part cost: Oven sensor (WB21X5301) costs $15–$30. ERC board (WB27X31900) costs $150–$300. Professional repair runs $120–$380.

Warning: F2 is a fire safety code. Do not continue using the oven until repaired. Keep the breaker off until diagnosis is complete.

F3 — Open Oven Sensor (RTD)

The F3 code means the oven temperature sensor circuit reads open — the ERC is getting no temperature data from the sensor. Without temperature feedback, the oven cannot heat safely.

Common causes:

• Broken sensor element (part WB21X5301) — the platinum RTD wire inside the probe has fractured
• Disconnected sensor plug at the back of the range
• Broken wire in the sensor harness (part WB27X25555) — especially where it passes through the oven cavity wall
• Thermal fatigue from self-clean cycles (the sensor operates at 900+ degrees F during self-clean)

How to fix:

1. Check the connector first: Power off at the breaker. Access the back of the range. Locate the oven sensor connector (2-wire plug). Reseat it firmly. If the connector was loose, restore power and test — a loose plug is the most common cause.
2. Test sensor resistance: Disconnect the sensor plug. Measure resistance: expect approximately 1,080 ohms at room temperature (70 degrees F). An open reading (OL/infinite) confirms the sensor has failed.
3. Trace the wiring: If the sensor reads normal at the sensor itself but open at the ERC connector, the wiring harness has a break. Flex the harness while measuring resistance to locate the break point.

Part cost: Oven sensor (WB21X5301) costs $15–$30. Sensor wiring harness (WB27X25555) costs $20–$40. Professional repair runs $100–$250.

F4 — Shorted Oven Sensor

The F4 code indicates the oven sensor reads very low resistance (near zero), meaning the sensor element is internally shorted or the wiring has a short circuit.

Common causes:

• Sensor element internally shorted — the platinum RTD wire has degraded
• Wire insulation damage where the sensor harness passes through the oven wall, causing wire-to-wire or wire-to-ground contact
• Moisture contamination in the sensor connector

How to fix:

1. Power off at the breaker. Disconnect the oven sensor plug.
2. Measure sensor resistance: a shorted sensor reads near 0 ohms or very low (under 200 ohms at room temperature). Normal is approximately 1,080 ohms at 70 degrees F.
3. If the sensor reads normal when disconnected, the wiring harness has a short to ground. Inspect the harness for damaged insulation, especially at the oven wall pass-through.
4. Replace the sensor or repair wiring as indicated.

Part cost: Oven sensor (WB21X5301) costs $15–$30. Professional repair runs $100–$250.

Note: A shorted sensor causes the ERC to read falsely high temperature, so the oven may refuse to heat or heat erratically. Replace promptly — prolonged operation with a shorted sensor can damage the ERC board.

F5 — ERC Board Internal Failure

The F5 code is the ERC board self-diagnosing its own internal failure. No amount of keypanel, sensor, or wiring troubleshooting will resolve F5 — the board itself must be replaced.

Common causes:

• Internal relay failure on the ERC
• EEPROM or microcontroller fault
• Power surge damage to board components
• Component aging (electrolytic capacitor dry-out)

How to fix:

1. Power cycle at the breaker for 5 minutes. If F5 returns immediately, the ERC has failed.
2. Visually inspect the ERC board: remove the back panel and look for burnt components, swollen electrolytic capacitors, cracked solder joints, or discoloration around the relay areas.
3. Replace the ERC board (WB27X31900). This is a model-specific part — verify your full model number before ordering. GE, GE Profile, and Cafe variants often look identical but have different firmware and relay configurations.

Part cost: ERC board (WB27X31900) costs $150–$300. Professional repair runs $250–$500 including diagnosis and programming.

F7 — Stuck Function Key

The F7 code specifically indicates a stuck function key on the keypanel — similar to F0 but the ERC has identified the fault as being in the function button area (bake, broil, self-clean, etc.) rather than the numeric keypad.

Common causes:

• Function button membrane delaminating — heavy use of bake/broil buttons wears the membrane contact layer
• Grease film from stovetop cooking migrating to the keypanel surface
• Ribbon cable partial contact (bent pins or corrosion affecting specific function key traces)

How to fix:

1. Press each function button firmly — if one feels mushy, stuck, or different from the others, it is likely the faulty button.
2. Clean the keypanel surface around all function buttons with a damp cloth.
3. Disconnect the keypanel ribbon cable and power on. If F7 clears, replace the keypanel membrane (WB27X32103).
4. If F7 persists with the keypanel disconnected, the ERC function key input circuit has failed — replace the ERC board.

Part cost: Keypanel (WB27X32103) costs $50–$100. Professional repair runs $130–$300.

F8 — ERC Relay / Board Failure

The F8 code indicates a non-recoverable internal relay or component failure on the ERC board — similar to F5 but typically associated with the power relay section of the board rather than the control logic.

Common causes:

• ERC relay welded shut or burned open from power surges
• Board component failure from Sacramento summer brownouts or lightning events
• Transformer failure on the ERC power supply section

How to fix:

1. Power cycle at the breaker for 5 minutes. If F8 returns, the ERC has failed.
2. Inspect the ERC board for visible damage — burning around relay areas, swollen capacitors, or transformer discoloration.
3. Replace the ERC board (WB27X31900). If both F5 and F8 appear in code history, the board suffered catastrophic failure.
4. Install a surge protector on the range circuit to prevent recurrence — Sacramento summer brownouts are a common trigger.

Part cost: ERC board (WB27X31900) costs $150–$300. Surge protector costs $30–$60. Professional repair runs $250–$500.

F9 — Door Lock Circuit Error

The F9 code means the oven door lock motor has failed to engage or disengage, or the door lock switch is not reporting the expected position. This code typically appears during or after a self-clean cycle.

Common causes:

• Door lock motor failure (part WB14T10093) — the motor that drives the lock mechanism
• Lock position switch failure — the switch that confirms lock/unlock status
• Wiring fault between the lock assembly and ERC
• Mechanical jam in the lock mechanism from carbon buildup (common after self-clean cycles)

How to fix:

1. If the door is stuck locked: Do not force it open. Wait for the oven to cool completely (can take 1–2 hours after self-clean). Once cool, power cycle at the breaker. The lock motor should attempt to unlock.
2. Manual release (if power cycle fails): Unplug the range. Remove the top panel. Locate the lock mechanism at the front of the oven. There is a manual release lever — push it to disengage the lock.
3. Test the lock motor: With power disconnected, disconnect the lock motor plug. Measure motor resistance — expect 20–50 ohms. If open, the motor has burned out.
4. Test the lock switch: Check continuity in both locked and unlocked positions.

Part cost: Door lock assembly (WB14T10093) costs $40–$80. Professional repair runs $120–$280.

FD — Meat Probe Shorted

The FD code indicates the meat probe circuit is shorted — either the probe itself has failed or the jack receptacle inside the oven is contaminated.

Common causes:

• Grease buildup inside the probe jack receptacle — the number one cause
• Meat probe internally shorted from heat damage or cable kink (part WB20X10025)
• Jack receptacle contamination from self-clean cycle residue

How to fix:

1. Remove the meat probe from the oven jack.
2. Clean the jack: Use a dry cotton swab to clean inside the probe jack receptacle. Grease and carbon deposits create a conductive path that mimics a shorted probe.
3. Test the probe: Measure resistance across the probe terminals at room temperature — expect approximately 50,000 ohms (50k). Near-zero resistance means the probe is internally shorted.
4. If no probe is inserted and FD still appears, the jack receptacle (part WB24X29252) has internal contamination or a failed contact. Clean with electrical contact cleaner first; replace if cleaning fails.

Part cost: Meat probe (WB20X10025) costs $15–$35. Probe jack (WB24X29252) costs $20–$40. Professional repair runs $80–$150.

Additional GE Oven Considerations

Double ovens: GE double ovens can show separate error codes for upper and lower cavities. The display typically prefixes the cavity (U for upper, L for lower) before the F-code. Each cavity has its own sensor and may have separate relay banks on the ERC. Diagnose each cavity independently.

Gas ranges: Gas GE ranges display the same F-codes as electric models, but the heating circuit includes the gas valve solenoids and igniter rather than electric elements. F2 on a gas range typically points to the oven sensor (not the gas valve) since the gas valve cannot overheat the oven by itself — it requires the sensor/ERC loop to regulate temperature.

Convection models: Convection ranges have an additional convection fan and, on some models, a convection heating element with its own thermal fuse. If the convection fan stops but the oven otherwise works, the convection motor or thermal fuse has failed — this may not trigger an F-code but results in uneven cooking.

Frequently Asked Questions

Q: How do I reset my GE oven after an error code? A: Turn off the breaker for 2 full minutes (GE ERC boards need a longer reset than most appliances). Restore power. If the code returns immediately, the component has failed and needs replacement. For intermittent codes that appear during self-clean, wait for complete cool-down before resetting — residual heat causes false sensor readings.

Q: Why does my GE oven show F3 during self-clean but not during normal baking? A: Self-clean cycles push the oven to 900+ degrees F, which stresses the temperature sensor at the limit of its operating range. A sensor that works fine at normal baking temperatures (300–500 degrees F) can fail at self-clean temperatures due to thermal fatigue. The platinum RTD element develops hairline fractures that only open at extreme heat. Replace the sensor (WB21X5301, $15–$30).

Q: My GE range blinks F2 and smells like smoke. What should I do? A: Disconnect power at the breaker immediately. F2 means over-temperature — the oven exceeded the safe limit. The smoke may be from food residue burning at abnormal temperatures or from an overheating component. Do not restore power until a technician verifies the sensor and relay are functional. This is a fire safety issue.

Q: Are GE oven parts covered by warranty? A: GE provides a 1-year full parts and labor warranty. The glass cooktop surface (on smooth-top ranges) has a 5-year limited warranty against cracking from thermal stress (not impact damage). No extended warranty applies to the ERC, sensor, or heating elements beyond year 1 without a GE Protection Plan.

Q: Can I replace the ERC board myself? A: Physically, yes — it is typically 4–6 screws and several wire connectors. However, ERC boards are model-specific and some require programming for your specific range configuration (gas vs. electric, single vs. double oven, convection options). Ordering the wrong board or failing to program it correctly results in a non-functional oven. Professional installation ensures correct part matching and programming.

When to Call a Professional

• F2 (over-temperature) — This is a fire safety code. Do not use the oven until a technician confirms the sensor and relays are functional.
• F5 / F8 (ERC failure) — Board replacement requires correct model matching and may require programming.
• F9 with door stuck locked — If the manual release does not work, a technician can safely access the lock mechanism without damaging the oven cavity lining.
• Gas valve or igniter issues — Any work on gas components should be performed by a licensed technician. Gas leaks are life-threatening.
• Multiple F-codes simultaneously — Indicates ERC failure or major electrical event requiring professional assessment.
• Any burning smell from the control panel area — Disconnect power immediately.
