Electrolux Cooktop Error Code E37

E37 indicates a break in the heat sink temperature sensor circuit within the 3-zone induction module that controls the left side cooking zones. The cooktop uses this sensor to protect the internal power electronics from overheating. When the sensor signal is lost, the system disables the affected zones and displays E37. The fault points to the generator circuit board, sensor, or the wiring connecting them.

A power reset by disconnecting the cooktop from power for several minutes may temporarily clear the error display, but E37 will return if the underlying fault is still present. Because the code indicates a physical break in a sensor circuit, the root cause must be repaired for the error to be permanently resolved. Resetting without a repair will not restore normal operation of the left side cooking zones.

Repair costs for E37 vary depending on which component has failed. If only a wiring harness or connector is at fault, costs may be relatively low, primarily covering labor. If the generator circuit board requires replacement, parts costs can range significantly depending on the specific model, with total repair bills typically falling somewhere between $150 and $400 or more when including professional labor. Getting a diagnostic estimate from a certified technician before authorizing repairs is advisable.

Resolving E37 involves accessing internal induction module components including the generator circuit board, heat sink sensor, and wiring harness. This requires disassembling the cooktop and working near high-voltage electronics, which is best handled by a qualified appliance technician. Knowledgeable DIYers who are comfortable with appliance electronics can start by inspecting the wiring harness and connector integrity before considering a board replacement.

When E37 is active, the affected left side cooking zones are typically disabled by the control system as a protective measure. You should not attempt to bypass this protection, as the heat sink sensor is a critical component that prevents the induction electronics from overheating. Avoid using the cooktop until the fault has been properly diagnosed and repaired.
