IceKing ice maker shows E7; unit may start but quickly stops ice production.

Safety first: Unplug the ice maker before reaching near the evaporator or moving parts.

Step-by-step checks:

• 1. Locate the ice thickness probe: On many IceKing models, a metal or plastic thickness sensor hangs near the evaporator plate where ice forms and is harvested.
• 2. Inspect alignment: Ensure the probe is positioned correctly according to the user manual—usually just touching or slightly above the ice surface when a slab forms.
• 3. Clean mineral deposits: Use a soft cloth and a food-safe descaler or vinegar solution to remove scale from the probe. Rinse and dry thoroughly.
• 4. Check mounting bracket: Verify the probe bracket is not bent or broken. A loose bracket can cause incorrect readings and E7 errors.
• 5. Inspect wiring: Follow the probe wires back to the control board. Confirm the connector is secure and wires are not damaged.
• 6. Replace sensor if needed: If cleaning and realignment do not clear the error, replace the ice thickness sensor assembly.

When to call a technician: If the evaporator area is heavily iced over or difficult to access, or if you are unsure of the correct probe position, a technician can adjust and calibrate the sensor.
