Jenn-Air Cooktop Error Code E9

E9 on a Jenn-Air cooktop means the coil temperature sensor has been detected as defective. The cooktop uses this sensor to monitor the heating element's temperature during operation. When the sensor signal is missing or out of range, the control board logs E9 and disables the affected cooking zone. Replacing the magnet pad or element assembly is the standard repair.

Disconnecting power temporarily may clear the displayed code, but the E9 error will return if the underlying sensor or element fault has not been corrected. A power reset alone is not a repair. The defective component, typically the magnet pad or element assembly, must be replaced to resolve the fault permanently.

Repair costs vary depending on the specific parts needed and whether you hire a professional technician. The magnet pad or element assembly is the most likely part required, and parts costs can range from roughly $50 to $200 or more depending on the model. Adding professional labor, total repair costs typically fall in the range of $150 to $400. Getting a diagnosis from a certified technician can help confirm which components need replacement before purchasing parts.

Yes, a knowledgeable DIYer can address this error by disconnecting power, replacing the magnet pad or element assembly, and carefully reassembling all parts and panels before restoring power. It is critical to ensure the unit is fully reassembled before operating it. If the error persists after replacing the element assembly, the wiring harness or control board may also need to be inspected.

You should not attempt to operate the cooktop while E9 is active. The error indicates the temperature sensor for that cooking zone is not functioning, meaning the cooktop cannot safely regulate heat on that element. Continued use without a working temperature sensor could create an overheating risk. Disconnect power and complete the necessary repairs before using the unit again.
