GE Cooktop Error Codes



The cooktop operates a self-diagnostic mode when power is applied. The touch board has error codes that can be utilized by the service technician in order to quickly identify failed or improper operation of certain cooktop components. To access failure codes, simultaneously press the TIMER ON/OFF and CONTROL LOCK pads for approximately 10 seconds. Error codes will blink in the window of the corresponding element. The replacement of the failed component will clear the error code.

Whenever a failure code is encountered and before attempting to replace any components: 1. Turn off the power supply for 30 seconds, then reset it to see if this clears the failure code. 2. Verify proper voltage and orientation of the power supply wiring connections.

Fault Codes for Electronic Control Cooktop

User Interface

F1x: UL “On” Indicator Light/LED failure. Replace Display Board (under Touch Board)

F7x: User Interface (UI) Button Matrix Error. Replace Touch Board.

F82: User Interface (UI) Microprocessor Error. Replace Display Board (under Touch Board)

Machine Control (MC)

F6x: UI cannot communicate with Machine Control. Check wires connecting UI to MC. Replace Machine Control. Replace Display Board (under Touch Board).

F81: Machine Control (MC) Microprocessor Error. Replace Machine Control.

“x” in above chart represents a number 0-9. The number represents a failed component on the board .

Flashing “F” in the Display

If a pan is removed or moved off-center from the cooking ring during the cooking process, the control will flash “F” along with the power setting. The flashing “F” indicates that the pan is no longer detected. After 30 seconds, the element will be deactivated and the display will turn off. If the pan is returned to the surface element within 30 seconds, the flashing “F” will disappear and cooking will resume.

Error Alerts (Flashing “E”/”c” and “E” “o”)




Error alerts indicate a temporary problem that may be corrected by the user.

Clear Keypad — If the display flashes “E” alternating to “c”, the keypad is sensing continuous activation of one or more keypads. Clean or clear any obstructions on the keypad area. Obstructions may be water, food spills, a utensil or other objects. To resume cooking, touch the ON/OFF pad, then select the power level.

Over Temperature — If the display flashes “E” alternating to “o”, the cooktop sensor indicates that the induction element or electronics have overheated.

Overheating of the element is caused by placing an empty pan on the element and selecting a high power level. The element sensor detects very high temperatures (above normal cooking temperatures), turns off the power and displays the error. A second potential cause of this error is a lack of cooling air to the bottom of the cooktop, which can cause overheating of the electronics. If this situation occurs, make sure the air inlet below the cooktop is unobstructed.

Touch the ON/OFF pad and allow the cooktop to cool for 30 to 45 minutes before operation can begin again. If either of these conditions persist, call for service.

IMPORTANT: If the “E” flashes alone, without alternating to a “c” or “o”, a hardware error has occurred. Call for service.

Control Lock: To unlock the cooktop: Touch and hold the CONTROL LOCK pad again for 5 seconds. A two-beep signal will sound, and the CONTROL LOCK light will go out, indicating that the cooktop is unlocked.

DEAD UNIT: Turn off circuit breaker, wait 30 seconds, and turn circuit breaker on. Proceed to tests below.

DISPLAY CHECK: Turn burner on Level 8. All segments should light. Set 4 burners to 1, 2, 5, and 8. Check for proper digit displays. When power is fi rst applied, all the segments light in a sequence. Check for a consistent pattern, none missing or doubled up.

VERSION DISPLAY: When the power is fi rst applied, after the display test sequence, the 4-digit version number of the touch board is momentarily shown in the display.

TOUCH KEYS IN GENERAL: Keys should respond to a grounded surface on the glass of 0.350-inch diameter, which is the model for a fi nger. Keys should not respond to a grounded surface less than 0.130-inch diameter. Water, etc., on the keys may cause them to not respond correctly because of unwanted ground coupling. However, the OFF function will respond regardless of contamination. If the contamination is severe enough to completely prevent touch key response, supervisory functions will turn off the burner. Removing the contamination should restore proper key operation. After cleaning the keypad glass (ensure the keypad is clean and dry), wait 30 – 60 seconds for keypad sensitivity to stabilize. A gap or moisture between the touch board and glass will affect touch key performance. If this occurs, the glass assembly should be replaced.

Hot Surface Indicator Light On

Some Freestanding radiant ranges provide four Hot Surface Light(s) on the backsplash or on the cooktop. Some of these models have one Hot Surface Light for each burner and others have one Hot Surface Light for the entire cooktop surface. When the glass around each burner goes above 150 degrees F, the hot surface light will come on to remind you that the surface is hot. After the unit is turned off, the light will remain on until the area around the burner has cooled to below 150 degrees F. This usually takes about twenty minutes. Some units also have Burner On indicator lights. As soon as you turn a burner on, the light will come on to indicate which burner you have selected. If the Hot light has not gone off after 45 minutes to 1 hour, or the burner continues to cycle with the knob turned to OFF, disconnect power to the range at the breaker or fuse box and contact service.

GE Cooktop Troubleshooting

ProblemPossible Cause
Surface elements will not maintain a rolling boil or cooking is slowImproper cookware being used. Use pans that are recommended for induction, have flat bottoms and match the size of the surface element.
Surface elements do not work properlyCooktop controls improperly set. Check to be sure the correct control is set for the surface element you are using.
Power arc ON indicator blinkingWrong pan type. Use a magnet to check that cookware is induction compatible.
Scratches on cooktop glass surfaceIncorrect cleaning methods being used. Use recommended cleaning procedures.
Areas of discoloration on the cooktopFood spillovers not cleaned before next use.
Plastic melted to the surfaceHot cooktop came into contact with plastic placed on the hot cooktop.
Pitting (or indentation) of the cooktopHot sugar mixture spilled on the cooktop.
Unresponsive keypad1. Keypad is dirty. Clean the keypad. 2. A fuse in your home may be blown or the circuit breaker tripped. Replace the fuse or reset the circuit breaker.
Pan detection/sizing not working properly1. Improper cookware being used. 2. Pan is improperly placed. 3. Cooktop control improperly set.
NoiseSounds you may hear: Buzzing, whistling and humming. These sounds are normal.
