Electrolux Cooktop Error Code E72

E72 indicates a low voltage output from the 12V power supply on the filter circuit board inside the 3-cook-zone induction module. This internal voltage rail is required for the module's control and generator circuits to operate correctly. The cooktop shuts down when this voltage drops below the required level. E72 is the same fault condition as error code E32 on these units.

No, the cooktop should not be used while E72 is active. The error indicates that a critical internal power supply is not functioning within specification, and the unit locks out operation as a protective measure. Attempting to force the cooktop to operate under this fault could risk damage to additional components.

Repair costs vary depending on which components need replacement and local labor rates. If only connections need reseating, cost is limited to a service call fee, typically in the range of $75 to $150. If the filter circuit board or generator circuit boards need replacement, parts and labor combined can range from $200 to $500 or more depending on parts availability and the technician's rates.

The first step, checking and reseating all cable connections on the filter circuit board, is something a confident DIYer can attempt after disconnecting power to the appliance. However, if connections are not the cause, the repair requires identifying and replacing the filter circuit board or generator circuit boards inside the induction module, which involves working with internal electronics and is best handled by a qualified appliance technician.

A power reset by switching off the circuit breaker for 30 to 60 seconds may temporarily clear the display, but E72 will return if the underlying hardware fault is not resolved. Because the code points to a physical component failure or connection problem, resetting alone is not a fix and the fault will reappear during operation.
