How to Fix / Troubleshooting
Safety first: Disconnect power before working on the door lock. Do not force the door open.
- Check for mechanical issues: Inspect the door strike and hinge for damage or misalignment that prevents full engagement with the lock.
- Access lock assembly: Remove the door gasket retaining band and unscrew the Midea door lock. Pull it out carefully.
- Inspect connectors: Ensure all lock connectors are firmly attached and wires are intact.
- Replace lock: If the lock does not click or hold when the cycle starts, or if continuity tests fail, replace the door lock assembly.
- Control issue: If a new lock does not resolve E30, the main PCB input circuit may be faulty and require professional service.
