Possible Causes
Upper zone NTC sensor failure, Upper zone fan not circulating air, Air duct between zones blocked, Main PCB upper zone control failure
How to Fix / Troubleshooting
Safety first: Disconnect power before removing shelves or panels.
Steps to resolve F1:
- Check airflow: Ensure that bottles are not blocking the air vents in the upper zone. Overloading can cause poor circulation and trigger faults.
- Inspect upper zone fan: If fitted, verify that the upper zone fan runs when cooling. Access it by removing the internal panel and check for obstructions or ice.
- Test upper zone sensor: Locate the upper zone cabinet sensor and measure its resistance at room temperature. Replace with a Hoover-compatible NTC if faulty.
- Clear ducts: If the cooler uses shared cooling between zones, ensure the air duct between upper and lower compartments is not blocked by ice or debris.
- PCB diagnosis: If fan and sensor are good but F1 persists, the upper zone control circuit on the main PCB may be defective and require replacement.
