How to Fix / Troubleshooting
Safety first: Disconnect power before testing the lock circuit.
- 1. Inspect the door lock assembly: Remove the front panel or gasket clamp to access the lock. Check for signs of overheating or melting.
- 2. Test lock coil resistance: Use a multimeter to measure the coil resistance and compare with Toshiba specifications. A very low resistance or short indicates a failed coil.
- 3. Check wiring harness: Follow the harness from the lock to the main PCB. Look for pinched, cut, or burnt wires. Repair or replace as needed.
- 4. Verify correct replacement: If the lock was recently replaced, ensure it is the correct Toshiba part number and wired correctly.
- 5. PCB diagnosis: If the lock and wiring are good, the control board's lock driver circuit may be damaged and should be replaced by a professional.
