Safety: Unplug the unit and allow it to cool before servicing. Surfaces near the condenser may be hot.

Improve ventilation: Ensure the Hoover ice maker has the recommended clearance on all sides and is not installed in a confined cabinet without airflow.
Clean condenser: Remove dust and lint from the condenser coil with a brush and vacuum. This is critical for proper heat rejection.
Check condenser fan: Confirm the fan runs whenever the compressor is on. If not, follow the condenser fan diagnostic steps and replace if necessary.
Inspect high‑temp sensor: Some models use a thermal sensor or thermal fuse attached to the condenser or compressor. Check for continuity (for fuses) or correct resistance (for sensors). Replace if open or out of spec.
Reset error: After correcting airflow and component issues, unplug the unit for 10 minutes to reset the control. If E13 returns quickly, further diagnosis of the control board and sensors is required.

E13 error, unit shuts down due to over‑temperature condition inside cabinet
