Electrolux Cooktop Error Code 18

Error code 18 indicates that the RF zone control circuit or the On/Off key sensor on the right side of the cooktop is reporting a fault. The cooktop's control system has detected an abnormal or missing signal from that sensor zone. This can be caused by a wiring issue or a failed Touch Control Board. The cooktop may disable cooking zones until the fault is resolved.

It is not recommended to continue using the cooktop while error code 18 is active. A defective On/Off key sensor or RF zone control could affect the cooktop's ability to properly detect control inputs, which may lead to unintended behavior. Disconnect power to the unit and have the fault diagnosed before resuming use.

Repair costs depend on whether the fix requires only reseating or cleaning connections or involves replacing the right side Touch Control Board. If board replacement is needed, parts and labor typically range from around $150 to $400 or more, depending on the specific model and local labor rates. Getting a diagnostic estimate from a technician before authorizing parts is advisable.

A knowledgeable DIYer can start by checking the cables and connectors leading to the right side Touch Control Board, since a loose or corroded connection is the first item to rule out. If the connections are intact and secure, the repair requires replacing the right side Touch Control Board, which involves working inside the appliance with the power disconnected. If you are not comfortable accessing internal components, a qualified technician should perform the replacement.

Cycling power to the cooktop may temporarily clear the display, but error code 18 will return if the underlying fault, such as a bad cable connection or a defective Touch Control Board, has not been corrected. A reset does not repair damaged components or loose wiring. The fault must be properly diagnosed and repaired to prevent the error from recurring.
