IceKing ice maker will not power on, display is blank or shows E1 shortly after startup.

Safety first: Unplug the ice maker from the wall outlet before removing any panels. Do not work on live circuits.

Step-by-step checks:

• 1. Verify power supply: Plug a lamp or known-good device into the same outlet to confirm the outlet has power. If there is no power, reset the breaker or use a different outlet.
• 2. Inspect power cord and plug: Check the IceKing power cord for cuts, burns, or kinks. Ensure the plug fits firmly in the outlet. Replace the power cord if damaged.
• 3. Access the control compartment: Remove the rear or side service panel (depending on model) using a screwdriver. Locate the main control PCB (usually behind the display or near the compressor compartment).
• 4. Check harness connections: Gently press all multi-pin connectors into the control board to ensure they are fully seated. Look for bent pins, corrosion, or signs of overheating.
• 5. Inspect board fuse: Many IceKing control boards have a small glass or ceramic fuse. If it appears blackened or the filament is broken, the fuse is blown. Only replace with the same rating and investigate for shorts before powering on.
• 6. Look for board damage: Examine the PCB for burnt spots, bulging capacitors, or cracked solder joints. Any visible damage usually means the board must be replaced.
• 7. Test restart: Reassemble panels, plug the unit back in, and power on. If E1 returns immediately and power supply is confirmed good, the main control PCB is likely faulty and should be replaced.

When to call a technician: If you are not comfortable testing live voltage or replacing a control board, contact a qualified appliance technician. Incorrect handling can cause electric shock or further damage.
