Electrolux Range Error Code E54

E54 indicates a break detected in the temperature sensor circuit for the right rear surface unit. The control is not receiving a valid signal from that sensor, so it shuts down the affected burner. This can be caused by a loose connector, a failed sensor, or damaged wiring between the sensor and the generator board.

When E54 is active, the right rear surface unit is generally disabled by the control system as a safety precaution. Other burners on the range may continue to function normally. It is best to avoid attempting to use the affected burner until the fault is diagnosed and repaired.

Repair costs depend on what component has failed. If only a connector needs to be reseated, costs are limited to a service call fee, typically in the range of $75 to $150. A replacement temperature sensor is generally a lower-cost part, while generator board replacement is more expensive and can bring total repair costs into the $200 to $500 range or higher depending on labor rates in your area.

A knowledgeable DIYer can start by checking that the sensor harness connector is firmly seated at the generator board, which requires accessing the internal components of the range. If the connector is secure and the fault persists, testing the sensor for continuity and inspecting the wiring for damage are the next steps. Replacing the sensor or generator board typically requires some disassembly and comfort working with appliance electronics.

Cycling power to the range by unplugging it or turning off the circuit breaker for a few minutes may temporarily clear the fault display, but if the underlying sensor break or wiring problem still exists, the code will return when the unit powers back up and runs a self-check. A reset alone will not fix the root cause.
