Electrolux Cooktop Error Code E52

E52 indicates a break or open circuit in the temperature sensor for the left rear cooking element. The sensor, which should read approximately 1000 ohms at room temperature through its blue wires, is not sending a valid signal to the generator circuit board. The cooktop disables the left rear zone until the fault is resolved. The cause is typically a failed sensor, damaged wiring, or a loose connector at the board.

The left rear zone will be disabled while E52 is active, so you cannot use that specific burner. The remaining cooking zones may continue to function normally. It is not advisable to attempt to bypass the error, as the temperature sensor is a critical safety component that prevents overheating of the element.

Resetting the cooktop by cycling power may temporarily clear the error display, but E52 will return as soon as the control system checks the left rear element sensor again. Because the code indicates a hardware fault, either a broken sensor, damaged wiring, or a loose connector, a reset does not address the underlying problem. The fault must be diagnosed and repaired for the error to clear permanently.

A knowledgeable DIYer can start by checking whether the blue sensor wire connector is fully seated at the generator circuit board, which requires no parts and no special tools. If the connector is secure, testing the sensor resistance with a multimeter across the blue wires is the next step. A reading far from 1000 ohms at room temperature confirms a failed sensor, and replacing the element or the board typically requires some comfort with appliance disassembly and electrical components.

Repair costs vary depending on which component has failed. If only the element needs replacement, parts typically range from $80 to $200 or more depending on the model. Generator circuit board replacement can cost between $150 and $400 for the part alone. Adding professional labor will increase the total, generally in the range of $100 to $200 for a qualified technician.
