Thermador Cooktop Error Code E0339

E0339 indicates a program execution error in the microcontroller of the right ADB induction module. This means the processor chip that controls the right side induction burner has failed to run its operating program correctly. The cooktop disables the affected zone to prevent unsafe operation. A power reset is the recommended first step to determine whether the fault is temporary or hardware-related.

When E0339 is active, the right induction zone is disabled by the cooktop's control system, so that burner will not generate heat. The remaining zones may continue to operate normally. It is not advisable to continue using the appliance in a faulted state without diagnosing the underlying cause, as repeated microcontroller faults can indicate a worsening electrical condition in the module.

Replacing an induction module involves working with high-voltage components and requires disassembling the cooktop, which carries a serious risk of electric shock if not done correctly. Induction modules store charge and must be properly discharged before handling. This repair is best performed by a qualified appliance technician with experience on induction cooktops. Attempting this repair without proper training and tools is not recommended.

A reset will clear the error if the fault was caused by a temporary condition such as a power surge or a brief voltage disruption. Disconnect the cooktop from mains power for at least 30 seconds, then reconnect and test the right induction zone. If the error returns immediately or after a short period of use, the fault is likely a hardware failure within the right induction module and will not be resolved by resetting alone.

Repair costs vary depending on whether the fault is a simple wiring issue or requires replacing the right ADB induction module. A service call and diagnostic typically runs in the range of $100 to $200. If the induction module needs replacement, parts and labor combined can range from $300 to $700 or more depending on the specific model and local labor rates. Getting a technician diagnosis before ordering parts is strongly recommended.
