Bosch Refrigerator Error Code 1011

Error code 1011 indicates an inverter fault caused by a short circuit or open circuit in the IGBT, which is the main power switching transistor on the inverter board. The inverter board controls the compressor motor, so this fault typically results in the compressor stopping and the refrigerator losing its ability to cool. The recommended first step is to replace the inverter board.

The refrigerator will not cool effectively when displaying error 1011, since the compressor is not operating. Food safety becomes a concern if temperatures rise above safe levels for extended periods. You should transfer perishables to another refrigerator and address the fault as soon as possible.

A power reset may temporarily clear the error display, but it will not resolve the underlying hardware failure in the inverter board. Error 1011 will return as soon as the refrigerator attempts to run the compressor again. The fault requires physical repair or replacement of the inverter board to be permanently resolved.

Replacing the inverter board is a task that experienced DIYers can attempt, but it involves working with high-voltage components and requires properly disconnecting power before starting. It is also important to test the compressor windings first, because installing a new inverter board onto a shorted compressor will likely damage the replacement board immediately. If you are not comfortable with electrical repairs, a qualified technician is the safer choice.

Repair costs typically depend on parts and labor in your area. Inverter board replacement parts alone generally range from around $100 to $300, and professional labor can add another $100 to $200 depending on the service provider. If the compressor has also been damaged, total costs will be significantly higher.
