Built‑in Danby ice maker shows F1 on the display; unit beeps and stops making ice.

Safety first: Unplug the built‑in ice maker and shut off water supply before servicing. Sealed system work must be done by a licensed technician.

Steps to troubleshoot F1:

• Check ambient conditions: Ensure the surrounding room temperature is within Danby’s specified range. Extremely hot rooms can cause high internal temperatures.
• Clean condenser coils: Pull the unit out (if built‑in) to access the rear or bottom condenser. Use a coil brush and vacuum to remove dust and lint.
• Verify condenser fan operation: With the unit powered (if safe), confirm that the condenser fan runs whenever the compressor is on. If the fan is not running, test and replace the fan motor.
• Inspect door/gasket (if applicable): For models with a door, check that the door closes fully and the gasket seals all around. Replace damaged gaskets.
• Monitor temperature: After cleaning and verifying airflow, allow the unit to run for several hours. If F1 returns and the ice compartment does not get cold, the sealed system (compressor, refrigerant, capillary tube) may be at fault.

Note: Sealed system diagnosis and repair require specialized tools and certification; contact an authorized Danby service provider.
