Electrolux Range Error Code E52

E52 indicates a break or open circuit detected in the temperature sensor for the left rear surface unit. The control system is not receiving a valid signal from that sensor, which prevents the burner from operating safely. The fault points to the sensor itself, the wiring harness, or the connector at the generator board.

You should avoid using the left rear burner while this fault is active, as the control system cannot accurately monitor that surface unit's temperature. Other burners on the range may still function normally depending on how the control system handles the fault. Operating a burner without functional temperature sensing creates a risk of uncontrolled overheating.

If the issue is just a loose connector, there is no parts cost involved. Replacing a surface unit temperature sensor typically costs in the range of $20 to $80 for the part, depending on the model. If the generator board itself is the cause, board replacement can range from $150 to $400 or more, and professional labor charges will add to the total.

A knowledgeable DIYer can start by checking whether the sensor connector at the generator board is fully and correctly seated, which requires no parts and no special tools. If the connector is secure, testing the sensor with a multimeter for continuity or correct resistance is the next step. Replacing the sensor or harness is a moderately involved repair, and working near the generator board on an induction range involves high-voltage components that require caution.

Power-cycling the range by disconnecting it from power for several minutes may temporarily clear the displayed code, but the error will return as soon as the control system re-checks the sensor circuit and finds the open condition. A reset does not address the underlying wiring or sensor failure, so a proper diagnosis is needed to resolve the fault permanently.
