How to Fix / Troubleshooting
Safety: Unplug the appliance before checking wiring.
- Inspect harness: Wiggle the ice maker wiring harness gently and look for intermittent operation or visible damage. Reseat connectors.
- Check door switch: Ensure the freezer door switch reliably turns the light on/off. Replace if intermittent.
- Monitor temperature: Use a thermometer to log freezer temperature over several hours. Large swings may indicate a defrost or control issue that must be addressed.
- Replace ice maker: If wiring and temperature are stable but behavior remains intermittent, replace the Bosch ice maker assembly.
