Electrolux Cooktop Error Code 3

Error code 3 on an Electrolux cooktop signals a defect in the left front zone control circuit or the On/Off key sensor on the touch panel. The cooktop's control system has detected an abnormal or missing signal from the left side touch control board. This can be caused by a wiring fault or a failure of the board itself.

It is not recommended to continue using the cooktop while error code 3 is active. A defective zone control or On/Off sensor can cause unpredictable behavior, including the inability to properly turn off a cooking zone. Discontinue use and address the fault before operating the appliance again.

If the issue is limited to a loose connection, there may be no parts cost involved, though a service call typically ranges from $75 to $150 depending on your area. If the left side touch control board requires replacement, parts and labor combined can range from $150 to $350 or more depending on the specific model and local labor rates. Getting a diagnosis from a qualified technician before purchasing parts is advisable.

A knowledgeable DIYer can start by inspecting and reseating the cable connections to the left touch control board, which requires removing the cooktop top panel or access cover. If connections are secure and the error persists, replacing the left side touch control board is the next step. Working inside the cooktop involves electrical components, so always disconnect power at the breaker before beginning any inspection or repair.

Disconnecting power at the breaker for several minutes and restoring it may temporarily clear the display, but if the underlying fault in the left touch control board or its wiring remains, the error code will return. A reset alone will not fix a defective board or damaged cable. The physical cause must be diagnosed and corrected for the error to clear permanently.
