What E55 means on a Electrolux range

The E55 error code on an Electrolux range indicates a break or open circuit condition detected in the temperature sensor associated with the right front surface unit. This sensor is part of the induction or radiant surface element control system, where a dedicated temperature sensor continuously monitors the cooking zone to regulate heat output and prevent overheating. When the control detects that the sensor circuit is open rather than reading a valid resistance value, it triggers E55 and disables the affected burner zone as a safety precaution.

The sensor connects to a generator board, which is the control module responsible for managing power delivery to the surface unit. A "break" in this context refers to an interruption in the sensor circuit, meaning the control board is receiving no signal or an out-of-range signal from the sensor. This can result from a physically broken sensor element, a damaged or corroded connector at the generator board, or a wiring harness that has been pinched, burned, or pulled loose from its connector seat.

The first diagnostic step is to inspect the sensor connector at the generator board for proper seating and signs of corrosion or heat damage. If the connector checks out, the sensor itself should be tested for continuity. A properly functioning sensor will read a measurable resistance value; an open reading confirms a failed sensor. Wiring continuity between the sensor and the generator board should also be verified before condemning either component.

Common causes of E55

  1. 01

    Loose or disconnected sensor connector

    Wiring / connection

    The temperature sensor connector may have come loose from its port on the generator board. Reseating the connector fully is the first step and can resolve the error without any parts replacement.

  2. 02

    Failed surface unit temperature sensor

    Part replacement

    The sensor element itself may have an internal break, causing an open circuit. Testing the sensor with a multimeter will reveal an open or out-of-range resistance reading if the sensor has failed.

  3. 03

    Damaged wiring harness

    Part replacement

    The wire harness running between the right front surface unit sensor and the generator board may be pinched, melted, or broken. Inspect the full length of the harness for visible damage or areas of heat exposure.

  4. 04

    Corroded or burned connector terminals

    Wiring / connection

    Heat and moisture over time can corrode the terminals at the sensor connector or generator board connector, creating high resistance or an open condition. Inspect terminals closely for discoloration, pitting, or buildup.

  5. 05

    Faulty generator board

    Part replacement

    If the sensor and all wiring test within normal parameters but the error persists, the generator board itself may be failing to read the sensor circuit correctly. This is the least common cause and should only be considered after other components are ruled out.

Frequently asked questions about E55

What does E55 mean on a Electrolux range?
E55 indicates a break or open circuit in the temperature sensor for the right front surface unit. The range uses this sensor to monitor and regulate heat at that burner zone. When the control detects no valid signal from the sensor, it triggers E55 and disables the affected burner to prevent unsafe operation.
Can I fix the E55 error myself?
A knowledgeable DIYer can start by checking that the sensor connector is fully seated at the generator board, which requires accessing the range interior. If the connector is secure, testing the sensor with a multimeter for continuity is the next step. Wiring repairs or component replacements involving the generator board are best handled by a qualified technician.
Is it safe to use my Electrolux range while E55 is displayed?
The right front surface unit will be disabled when E55 is active, so that burner should not be used. Other burner zones may continue to operate normally depending on how the range responds to the fault. It is best to address the error promptly rather than continuing to use the appliance in a degraded state.
Will resetting the range clear the E55 error code?
Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the error display, but E55 will return if the underlying sensor break or connection problem is not corrected. A reset alone does not repair a faulty sensor, broken wire, or loose connector.
How much does it cost to repair an E55 error on an Electrolux range?
Repair costs vary depending on the root cause. If only a connector needs reseating, the cost is limited to a service call fee, typically in the range of $75 to $150. Replacing a failed temperature sensor generally adds $50 to $150 in parts. If the generator board requires replacement, total repair costs including parts and labor can range from $200 to $500 or more.
