Fisher & Paykel Freezers F6 Error: Ice maker sensor fault
Fisher & Paykel freezer error code F6 is a low-severity fault meaning Ice maker thermistor or ice-zone sensor fault. The main freezer compartment continues to operate normally with an F6 fault. A power-cycle will clear a transient F6 fault.

Answer to continue safely
Is it safe to keep using?
Yes. The main freezer compartment continues to operate normally with an F6 fault. Food safety is not at risk. Only ice-making function is affected. Schedule repair or thermistor replacement at your convenience.
Can I reset the code?
Yes. A power-cycle will clear a transient F6 fault. If the code returns after the ice maker attempts its first harvest cycle, the thermistor or its wiring requires physical inspection and replacement.
When to stop immediately?
Stop if you notice: F6 appears alongside other fault codes such as F2 or DEF that affect main freezer cooling.
Symptoms You May Notice
F6 code on display
The control panel shows F6, indicating a fault in the thermistor monitoring the ice maker zone or ice-making compartment temperature.
Ice maker stops producing ice
The ice maker halts operation because the controller cannot confirm the ice zone has reached the temperature required to complete a harvest cycle.
Freezer compartment continues cooling normally
The main freezer compartment is not affected by an F6 fault — only the ice maker function is impaired.
Possible Causes
Failed ice-maker zone thermistor
The NTC sensor that monitors ice maker compartment temperature has failed open or short, returning an out-of-range resistance value.
DIY PossibleLoose connector at ice maker module
The wire harness connector between the ice maker thermistor and the main PCB has come loose.
DIY PossibleIce bridging in sensor location
Frost or ice has built up around the thermistor probe in the ice maker compartment, altering its reading.
DIY PossibleIce maker module fault
The ice maker module itself has a fault that affects the thermistor input circuit within the module.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle and check ice maker
Unplug the freezer for 5 minutes, restore power, and wait 30 minutes to see whether the ice maker resumes operation and F6 clears.
If ice had built up around the sensor during a defrost anomaly, a power-cycle and short run cycle may clear the fault as the ice melts.
-
2
Defrost the ice maker compartment
Turn off the ice maker, unplug the freezer, and allow the ice maker zone to reach room temperature. Dry the interior and the sensor area before restoring power.
Ice bridging around the thermistor probe is often visible as a localized frost deposit on or near the sensor body.
-
3
Inspect thermistor and connector
After defrosting and unplugging, locate the ice maker thermistor, check the connector is fully seated, and test sensor resistance with a multimeter.
The ice maker thermistor should read within a consistent range for the compartment temperature. Open circuit (OL) confirms failure.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Code persists after thermistor replacement, indicating a fault in the ice maker module circuit board
- Ice maker module requires replacement — a component that involves water line disconnection
