GE Cooktop Error Codes: Complete List with Fixes

GE cooktops — induction, radiant electric, and gas models with electronic ignition — each have their own control systems and error codes. Induction cooktops, in particular, use sophisticated electronics with multiple sensors per burner zone. When the control board detects a fault, it displays an error code on the burner indicator or central display. This guide covers every GE cooktop error code across all cooktop types with real part numbers and step-by-step fixes.

How GE Cooktop Error Codes Work

GE cooktops use different control architectures depending on the type:

Induction cooktops have the most complex electronics — each burner zone has its own inverter board that converts household AC power to high-frequency AC that generates a magnetic field in the cookware. A master control board coordinates all zones and monitors temperatures, current draw, and user input. Error codes on induction models are the most frequent.

Radiant electric (glass-top) cooktops use a simpler relay-based control board that switches heating elements on and off based on the selected power level. Error codes are less common but indicate relay failures, sensor issues, or element problems.

Gas cooktops with electronic controls have limited error codes since the gas burner itself is simple, but the electronic ignition module, spark electrode, and flame sensor can generate fault codes on models with digital displays.

Service Mode entry (induction models): Touch and hold the Power and Lock buttons simultaneously for 5 seconds. The display enters diagnostic mode showing stored fault codes and zone status.

Service Mode entry (radiant electric): Varies by model. Most use a two-button hold combination specific to the control panel layout. Refer to the tech sheet (taped inside the junction box cover or behind the access panel).

F1 — Control Board Communication Error

The F1 code on GE cooktops indicates a communication failure between the master control board and one or more zone inverter boards (induction) or between the control board and the touch panel interface.

Common causes:

• Inverter board failure for a specific zone (induction cooktops)
• Communication ribbon cable between touch panel and control board disconnected or damaged
• Master control board failure
• Power surge damage to communication bus ICs

How to fix:

1. Power cycle at the breaker for 2 minutes. Communication glitches from power fluctuations often clear with a full reset.
2. Identify the affected zone: If F1 only appears when a specific zone is selected, that zone's inverter board has likely failed. On GE induction cooktops, each zone has a dedicated inverter module mounted under the glass top.
3. Check connections: Disconnect power. Remove the cooktop from the counter (typically secured by clips or screws from below). Inspect all ribbon cable and wire harness connections between the touch panel, master board, and zone inverter boards. Reseat any loose connectors.
4. Test individual zones: Restore power and test each zone individually. A zone that generates F1 when activated has a failed inverter board. Zones that work correctly have functioning inverters.
5. Replace the failed inverter or master control board as indicated by the diagnostic results.

Part cost: Zone inverter board costs $80–$150. Master control board costs $120–$250. Touch panel assembly costs $60–$120. Professional repair runs $200–$400.

F4 — Overheating / Thermal Shutdown

The F4 code indicates the cooktop has detected excessive temperature either at a burner zone, on the glass surface, or at the control electronics. The cooktop shuts down the affected zone or all zones as a safety measure.

Common causes:

• Cookware left on a zone at high power with no contents (dry heating)
• Excessive ambient temperature under the cooktop from poor ventilation
• Failed zone temperature sensor (thermistor)
• Inverter board overheating from blocked cooling fan (induction models)
• Control board overheating from confined installation space

How to fix:

1. Let the cooktop cool down. F4 on induction models triggers a thermal lockout that only resets after the temperature drops below the safe threshold. This can take 15–30 minutes.
2. Check ventilation: GE induction cooktops require clearance underneath for the cooling fan. If the cooktop is installed over an oven with reduced ventilation (drawer oven, storage drawer), the electronics overheat during extended use. Verify that the ventilation requirements in the installation guide are met.
3. Listen for the cooling fan: GE induction cooktops have an internal fan that runs during and after cooking. If you never hear the fan, it may have failed. Access the fan (underneath the cooktop) and check for obstruction or motor failure.
4. Test the zone thermistor: Disconnect power. Access the temperature sensor for the affected zone (mounted under the glass near the zone coil). Measure resistance — expect approximately 100k ohms at room temperature for NTC thermistors used in GE cooktops. Open or shorted readings indicate failure.

Part cost: Zone thermistor costs $15–$35. Cooling fan motor costs $30–$60. Professional repair runs $150–$300.

F6 — Pan Detection Error (Induction Only)

The F6 code appears exclusively on GE induction cooktops. It means the zone cannot detect compatible cookware — the induction coil is energized but no magnetic coupling is established.

Common causes:

• Non-induction-compatible cookware (aluminum, copper, glass, ceramic without magnetic base)
• Cookware too small for the selected zone (the pan must cover at least 60 percent of the zone diameter)
• Pan bottom warped or not flat against the glass (air gap prevents magnetic coupling)
• Zone coil failure or broken ferrite core
• Pan detection sensor (current sensor) failure

How to fix:

1. Verify cookware compatibility: Hold a magnet to the bottom of your pan. If it sticks firmly, the cookware is induction-compatible. If the magnet slides or does not stick, the pan will not work on induction.
2. Check pan size and condition: The pan bottom must be flat (no warping) and must cover at least 60 percent of the zone marking on the glass. A 6-inch pan on an 11-inch zone will trigger F6.
3. Test with known-good cookware: Use a cast iron skillet (the most reliably induction-compatible material) to test the zone. If the zone works with cast iron but not with other pans, the cookware is the issue.
4. Zone coil test: If F6 appears with verified compatible cookware on a specific zone, the coil or current sensor for that zone may have failed. This requires professional diagnosis with the cooktop removed from the counter.

Part cost: Zone coil assembly costs $100–$200. Current sensor costs $20–$40. Professional repair runs $200–$400.

F7 — Voltage Error

The F7 code indicates the control board has detected incoming voltage outside the acceptable range. GE induction cooktops require a stable 240V AC supply; radiant electric cooktops also use 240V.

Common causes:

• Household voltage too low (below 210V) or too high (above 260V)
• Loose wire connections in the cooktop junction box
• Corroded terminal block contacts
• Breaker providing inconsistent voltage (worn contacts)
• Sacramento summer brownouts causing voltage sags during peak demand

How to fix:

1. Measure incoming voltage: At the cooktop junction box (or at the outlet for plug-in models), measure voltage between the two hot legs. Normal reading is 228–252V AC. Below 210V or above 260V triggers F7.
2. Check the breaker: GE cooktops require a 40-amp (induction) or 30-amp (radiant) dedicated 240V circuit. Toggle the breaker off and back on. If the breaker feels loose or warm, have an electrician replace it.
3. Inspect the junction box: Disconnect power. Open the cooktop junction box and check all wire connections. Tighten any loose wire nuts or terminal screws. Look for discoloration or heat damage on the terminals, which indicates arcing from a poor connection.
4. Voltage regulator (chronic): If your area has frequent voltage fluctuations (common in Sacramento during summer), consider a whole-house voltage regulator or a dedicated line conditioner for the cooktop circuit.

Part cost: Terminal block costs $15–$30. Junction box wire repair is labor-only ($50–$100). Professional electrical diagnosis runs $100–$200.

F9 — Touch Panel Error

The F9 code indicates the touch panel (capacitive touch sensor) is malfunctioning — registering phantom touches, not responding, or sending corrupted signals to the control board.

Common causes:

• Liquid on the touch panel surface — water, oil, or food residue creates false touch signals
• Cracked glass surface allowing moisture under the touch sensor layer
• Touch panel control IC failure from power surge
• Ribbon cable between touch panel and control board damaged

How to fix:

1. Clean the surface: Wipe the entire cooktop surface with a clean, dry cloth. Cooktop cleaner residue can create conductive films that interfere with capacitive touch sensing.
2. Check for cracks: Inspect the glass surface under good light for hairline cracks. Even microscopic cracks can allow moisture to reach the touch sensor layer, causing erratic behavior. A cracked cooktop glass must be replaced entirely — it is a safety hazard.
3. Power cycle: Turn off the breaker for 2 minutes. A power cycle resets the touch panel controller IC.
4. Inspect the ribbon cable: Disconnect power and remove the cooktop from the counter. Check the ribbon cable between the touch panel and the master control board for damage, corrosion, or loose connections.

Part cost: Touch panel assembly costs $60–$120. Glass surface replacement costs $200–$500 (model-dependent). Professional repair runs $150–$350.

Additional GE Cooktop Error Codes Quick Reference

• F2 — Zone over-current. The inverter board detected current draw exceeding the safe limit. Usually indicates a failed inverter board IGBT transistor or shorted zone coil winding. Professional repair required.
• F3 — Zone sensor open. The temperature sensor for a specific zone reads open (infinite resistance). Check sensor connection and replace if resistance is out of spec. Costs $15–$35 for the sensor.
• F5 — Cooling fan failure (induction). The fan speed sensor detects zero RPM when the fan should be running. Check fan motor and wiring. Fan motor costs $30–$60.
• F8 — EEPROM error. The control board's memory chip has corrupted data. Power cycle first; if F8 persists, replace the control board.
• E1 — Flame failure (gas cooktops with electronic controls). The flame sensor does not detect a flame within 8 seconds of ignition. Check spark electrode gap, flame sensor, and gas supply.
• E2 — Ignition failure (gas cooktops). The igniter sparks but gas does not reach the burner. Check gas valve solenoid and supply pressure.
• LOC — Control lock active. Not an error. Press and hold the Lock button (or designated button pair) for 3–5 seconds to deactivate.
• HOT — Surface hot warning. Not an error — the glass surface is still above 150 degrees F. Wait for cool-down before cleaning.

GE Cooktop Diagnostic Mode

Induction models: Touch and hold Power + Lock for 5 seconds. The display shows stored error codes for each zone (Zone 1 through Zone 5, if applicable). Use the + and - touch controls to scroll through the code history. Zone-specific codes help isolate the failed inverter board.

Radiant electric models: Service mode varies by model. Common entry: hold two opposing zone power controls simultaneously for 5 seconds. Some models require accessing the tech sheet behind the cooktop access panel for the specific button combination.

Gas models with electronic panels: Hold the ignition and timer buttons for 5 seconds. Electronic gas cooktops have fewer diagnostic features since the gas burner system itself is predominantly mechanical.

Frequently Asked Questions

Q: How do I reset my GE cooktop after an error code? A: Turn off the breaker for 2 minutes, then restore power. Most cooktop error codes clear after a full power cycle. For induction models showing F4 (overheating), you may need to wait an additional 15–30 minutes for the electronics to cool down before the reset takes effect. If the code returns immediately after reset, the component has failed.

Q: Why does my GE induction cooktop show F6 with my stainless steel pans? A: Not all stainless steel is induction-compatible. Only stainless steel with a magnetic (ferritic) base layer works with induction. High-quality stainless steel cookware from brands like All-Clad and Demeyere use a magnetic base specifically for induction compatibility. Test with a magnet — if it sticks firmly to the bottom, the pan is compatible. If it slides or does not stick, the pan lacks sufficient magnetic material.

Q: My GE radiant cooktop has a hot element that will not turn off. Is this an error code issue? A: A stuck-on element is a relay failure on the control board — the relay welded shut from arcing. This is a fire safety issue. Disconnect power at the breaker immediately. This may or may not generate an error code depending on the model. The control board must be replaced.

Q: Are GE cooktop parts covered by warranty? A: GE provides a 1-year full parts and labor warranty. The glass cooktop surface has a 5-year limited warranty against thermal cracking (not impact or scratch damage). Induction inverter boards and touch panels are covered only during the first year. No extended warranties apply beyond year 1 without a GE Protection Plan.

Q: Can I install a GE induction cooktop over a wall oven? A: Yes, but only over GE-approved wall ovens that provide adequate ventilation clearance. The induction electronics generate heat that must dissipate downward. Installing over a non-approved oven or over a storage drawer with insufficient clearance causes chronic F4 (overheating) codes. Verify compatibility in the GE installation guide for your specific cooktop model.

When to Call a Professional

• F2 (zone over-current) — Indicates inverter board IGBT failure. High-power electronics (4,800W per zone on large induction elements) require professional handling. Risk of electrical shock from stored capacitor charge.
• F4 with adequate ventilation — If overheating persists after confirming proper installation clearances, an internal component is failing.
• F7 (voltage error) — Electrical supply issues require a licensed electrician for diagnosis and correction.
• Cracked glass surface — A cracked cooktop is a shock hazard (especially induction) and must be replaced. Glass replacement requires removing the cooktop from the counter.
• Gas burner issues (E1/E2) — Gas valve and ignition system repairs should be performed by a licensed technician.
• Multiple zone failures — When two or more zones show errors simultaneously, the master control board has likely failed.
