Possible Causes

Freezer compartment NTC sensor open circuit, Loose sensor connector at PCB, Damaged harness inside cabinet insulation, Faulty main PCB sensor input

How to Fix / Troubleshooting

Safety: Unplug the freezer before removing any internal panels.

Steps to address F1 (freezer sensor):

  • 1. Locate freezer NTC: In many Leisure upright freezers, the freezer sensor is behind the rear liner or clipped to the evaporator. Remove the inner rear panel if necessary.
  • 2. Inspect sensor and wiring: Look for signs of damage, corrosion, or dislodged clips.
  • 3. Test resistance: Disconnect the sensor and measure resistance at room temperature. Compare to expected NTC values. Replace if open or out of range.
  • 4. Replace sensor: Install a new Leisure freezer compartment NTC sensor, routing the cable along the original path.
  • 5. Check PCB connection: Reseat the sensor connector on the main PCB.
  • 6. Restore power and test: The F1 code should clear once the control detects a valid sensor reading.
