What E0244 means on a Thermador cooktop

Error code E0244 on a Thermador induction cooktop indicates a communication failure between the microcontroller and the ASIC (Application-Specific Integrated Circuit) located on the power board. The ASIC is a dedicated chip responsible for managing the high-frequency switching and power delivery functions of the induction module. When the microcontroller cannot establish or maintain a reliable data exchange with this chip, the control system flags E0244 and disables the affected induction zone to prevent uncontrolled operation.

This type of communication fault is typically internal to the power board assembly itself. The signal lines between the microcontroller and ASIC are part of the same board circuit, meaning the failure is almost always a hardware-level issue within the power board rather than an external wiring or sensor problem. Causes can include component-level failures on the board, solder joint degradation from thermal cycling, or corruption of the ASIC's internal logic due to voltage transients or overheating.

Because the fault originates within the power board's integrated circuitry, the standard diagnostic path is direct replacement of the power board. There is no field-level repair procedure for the ASIC or microcontroller communication pathway itself. Technicians should confirm the error is not caused by a loose board connector before condemning the board, but in most cases the board must be replaced to restore normal induction module operation.

Common causes of E0244

  1. 01

    Failed power board ASIC or microcontroller

    Part replacement

    The ASIC or microcontroller chip on the power board has failed internally, breaking the communication link. This is the most common root cause and requires full power board replacement.

  2. 02

    Degraded solder joints on the power board

    Part replacement

    Repeated heating and cooling cycles can cause solder joints connecting the ASIC or microcontroller to crack and lose continuity. Visual inspection may reveal hairline fractures around chip leads, though many cracks are not visible without magnification.

  3. 03

    Voltage transient or power surge damage

    Part replacement

    A power surge can corrupt or permanently damage the ASIC's internal logic, triggering a persistent communication fault. If the error appeared after a power event, the board is likely damaged.

  4. 04

    Loose or unseated board connector

    Wiring / connection

    A connector linking the power board to the rest of the control system may have worked loose over time. Inspect and firmly reseat all connectors to the power board before replacing it.

Frequently asked questions about E0244

What does E0244 mean on a Thermador cooktop?
E0244 indicates a communication failure between the microcontroller and the ASIC on the induction module power board. These two chips must exchange data continuously for the induction zone to operate safely. When that communication breaks down, the cooktop logs E0244 and disables the affected zone. The fault is internal to the power board assembly.
Can I fix E0244 myself, or do I need a technician?
Resolving E0244 requires replacing the power board, which involves working inside a high-voltage appliance. Induction cooktops retain dangerous voltage levels even after being unplugged. Most homeowners should have a qualified appliance technician handle this repair to avoid risk of electric shock.
Will resetting the cooktop clear the E0244 error?
A power reset by unplugging the cooktop or cycling the circuit breaker may temporarily clear the display, but the error will return if the underlying power board fault remains. E0244 reflects a hardware failure, not a software glitch, so a reset is not a fix.
Is it safe to use my Thermador cooktop while E0244 is active?
The cooktop disables the affected induction zone when E0244 is active, which prevents uncontrolled heating on that zone. You should not attempt to bypass or ignore the fault. Continued use of other zones is generally possible, but having the cooktop inspected and repaired promptly is the recommended course of action.
How much does it cost to repair a Thermador cooktop showing E0244?
Repair costs depend on the specific power board part and local labor rates. Parts alone for an induction power board typically range from $150 to $400 or more depending on the model, with professional labor adding another $100 to $250. Getting a quote from a Thermador-authorized service provider before committing to the repair is advisable.
