Freezer shows F18 and may not recognize internal accessories such as ice maker (if fitted)

Safety first: Unplug the freezer before working near the ice maker or accessory modules.

Steps:

• 1. Verify accessory presence: Ensure the freezer is actually equipped with the accessory (e.g., ice maker) that F18 refers to.
• 2. Inspect harness: Locate the wiring to the accessory (often in the upper compartment) and check for damage or loose plugs.
• 3. Check connectors: Disconnect and reconnect the accessory connector to clean contacts.
• 4. Module substitution: If wiring is intact, the accessory module (e.g., ice maker) may be defective and require replacement.
• 5. Control board: If a new accessory module does not resolve F18, the main control board's accessory interface may be faulty.
