Maytag Cooktop Error Code LOCKED LED

On a Maytag cooktop, the LOCKED LED illuminating at power-on with no elements selected indicates a checksum failure on the control board. This means the board's internal memory data is corrupted or invalid. It is not a user-activated lock condition. The control board must be replaced to resolve the issue.

When the LOCKED LED error is active due to a checksum failure, the control board has not initialized correctly. You should not attempt to use the cooktop until the board is replaced, as the controls may not respond predictably or at all.

Repair costs depend on the specific control board required and whether you hire a technician. Control board parts for cooktops generally range from $100 to $300 or more depending on the model. If you use a professional repair service, expect to add labor costs on top of the part price, typically bringing the total into the $200 to $500 range.

The only repair for this error is replacing the control board. There are no wiring connections, sensors, or burner components to test since the failure is internal to the board itself. A confident DIYer comfortable with appliance disassembly can complete this repair, but if you are unsure, a qualified technician is recommended.

No. Because this error results from corrupted data stored inside the control board's memory, cycling power or performing a reset will not restore valid data. The LOCKED LED will return every time power is applied until the control board is replaced.
