Unit powers on but does not start ice making; fans and compressor do not run.

Safety first: Unplug the unit before removing panels. Avoid touching compressor terminals.

Steps to diagnose no start:

• Check for error messages: Look at the display for any codes like ICE FULL or ADD WATER. Resolve those first.
• Reset the unit: Turn the power off, unplug for 10 minutes, then plug back in and press power to start a cycle.
• Listen for relays: When starting, you should hear a click from the control board as the compressor relay engages. No click may indicate a bad relay or board.
• Inspect board: Remove the panel to access the main control board. Look for burnt spots or swollen components near the compressor relay.
• Check capacitor (if present): Some Silonn models use a compressor start capacitor. If it is bulged or leaking, it should be replaced.
• Replace board or capacitor: If the relay is not energizing and sensors are OK, replace the control board. If the relay clicks but the compressor hums and trips, replace the start capacitor.

When to call a professional: Compressor start issues can be complex; if unsure, contact a technician.
