How to troubleshoot an E9 error on a GE induction cooktop
Steven E / Wednesday July 24, 2024
Even the most advanced appliances can encounter problems over time, and one such challenge that GE induction cooktop users may encounter is the E9 error code.
But don’t worry — we’re here to help you troubleshoot and resolve the error code without an expensive service call or technician.
If you find out that you need any replacement parts for your GE cooktop while you’re troubleshooting, you can enter your model number at AppliancePartsPros.com to order them. Most orders arrive in just two business days, and we have thousands of free guides to show you how to install your new parts.
Important: The error code information 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 E9 error mean?
The E9 error typically signifies a problem where either the rate of temperature increase is too rapid or an open sensor is detected within the cooktop’s system. This may happen if the cookware heats up quickly and the sensors detect an abrupt temperature rise. It can also occur if the cookware being used isn’t compatible with the induction cooktop. Since induction cooktops require cookware with magnetic properties, incompatible cookware that doesn’t make proper contact with the cooktop’s surface can lead to rapid temperature changes that may trigger the error.
Another potential cause is a bad RTD (Resistance Temperature Detector) sensor. This means that a sensor within the cooktop’s system isn’t providing the expected readings.
In some cases, the E9 error can be triggered by overheating of the cooktop’s electronics. This can happen if there are blockages or obstructions in the ventilation system.
Pro tip: You can recall stored error codes in your cooktop by pressing the Timer on/off and Control Lock buttons at the same time for 10 seconds. Error codes will appear in the display window for the element that has a problem.

Safety precautions
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 eliminating any risk of electric shock.
- If the appliance has recently been used, give it plenty of time to cool down before working on it.
- 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.

First checks
- Check the cookware you’ve been using on the induction element. Make sure it’s compatible and has magnetic properties.
- Make sure that you’re not using an oversized or inappropriate pan that might cause rapid temperature increases.
- Check the vents on the cooktop to make sure there aren’t any blockages that could hinder proper heat dissipation. If you find any dust or debris, remove it.
How to troubleshoot the E9 error
Follow these steps to find out what’s causing the E9 fault code on your GE induction cooktop.
- Make sure the cooktop is disconnected from the power source.
- Use a screwdriver to carefully remove the external screws from all four sides of the burner box.
- Lay a towel down or prepare a padded surface for the glass surface to be set on.
- Gently lift the glass surface off the burner box. Be very cautious during this step to avoid damage to the glass. Place the glass on a towel or padded surface to prevent scratches.
- Access the terminated element wires that are connected to the generator board. Use your screwdriver to loosen the screws holding these wires in place.
- Carefully lift the element connectors from the generator board.
- Remove the heating elements from their locating pegs.
- Remove the screws holding the shield to the generator modules and slowly lift the shield partway. If there are any ground wire connections, detach them carefully. Then, lift the shield off the cooktop.
- Set a multimeter to resistance mode and use the probes to test the sensor connection to the generator board. You should get a reading of about 1k Ohms on the sensor at room temperature. If the RTD sensor shows a resistance outside of the normal range (plus or minus 10%), the sensor will need to be replaced. (Some models may only make the sensor available with the element as an assembly.)
If the sensor tests within the normal range, the element can also be tested for resistance. The element should read less than 1 Ohm of resistance at room temperature. If it’s outside of that range, it should be replaced.
If the sensor and element both pass testing, then the control board should be replaced as a last resort.
