Electrolux Cooktop Error Code 8

Error code 8 indicates that the cooktop has detected a fault in the left rear (LR) cooking zone control sensor or the On/Off key sensor. These sensors are part of the left side Touch Control Board assembly. The cooktop flags this code when the sensor circuit produces an out-of-range or missing signal. Diagnosis starts with checking the wiring and connectors before considering board replacement.

It is not advisable to continue using the cooktop while error code 8 is active. The fault indicates the LR zone or On/Off sensor is not functioning correctly, which could cause unreliable zone control or prevent the cooktop from turning off properly. Discontinue use and address the fault before resuming cooking.

If only a cable or connector is at fault, repair costs are minimal and may only involve a service call fee, typically in the range of $75 to $150. If the left side Touch Control Board requires replacement, the total cost including parts and labor generally falls between $150 and $350 depending on the specific model and local labor rates. Getting a diagnostic estimate before authorizing repairs is recommended.

A knowledgeable DIYer can begin by checking all cable connections to the left side Touch Control Board for looseness or damage, which requires no replacement parts. If connections are secure and the error persists, replacing the left side Touch Control Board is the next step. Board replacement involves working inside the cooktop and disconnecting power first, so comfort with appliance disassembly is recommended.

A power reset, such as turning off the breaker for one to two minutes and restoring power, may temporarily clear the error if the cause is intermittent, such as a loose connection or residual moisture. However, if the left side Touch Control Board sensor is genuinely defective, the error code 8 will return. A reset alone is not a repair and should be followed by a full diagnostic check.
