Freezer displays E6 and the compressor does not run or stops shortly after starting.

Critical safety warning: The compressor and inverter circuitry operate at mains voltage and can store charge. Unplug the freezer and wait several minutes before touching any components. If you are not experienced with high-voltage electronics, contact a professional.

Steps:

• 1. Verify power supply: Confirm the outlet voltage is within Toshiba's specified range using a multimeter. Low or unstable voltage can trigger E6.
• 2. Access electronics: Remove the rear lower cover to access the compressor, inverter module (if equipped), and main PCB.
• 3. Check wiring: Inspect the harness between the main PCB and inverter module, and between the inverter and compressor terminals. Look for loose plugs, burn marks, or melted insulation.
• 4. Inspect inverter board: Look for obvious damage such as burnt components or bulging capacitors. If present, the inverter board should be replaced.
• 5. Resistance test of compressor windings: With the unit unplugged and inverter disconnected, measure resistance between compressor terminals (for 3-phase inverter compressors, all three readings should be similar and not shorted to ground). Abnormal readings indicate a faulty compressor.
• 6. Replace components: Replace a defective inverter module or main control PCB with Toshiba-approved parts. Compressor replacement should be done only by certified refrigeration technicians due to refrigerant handling requirements.
