Code 6 reports the freezer (FC) sensor resistance as too low.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so 6 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Resistance of the FC (freezer) sensor is below 660 ohms, outside the normal range.
On Active Smart models, code 6 reports that the FC (freezer) sensor has a resistance under 660 ohms, outside the normal range. Treat it as the other half of code 5, which covers the same sensor reading too high.
What the manual prescribes
Primary: inspect where the sensor is connected to the power module.
Secondary: fit a new sensor.
No other step is listed for this code, and nothing is given for the owner to do.
Does it mean the freezer is warm?
Not by itself. In the manual’s table, resistance drops as the sensor gets warmer, yet the manual presents this as a sensor resistance fault. The table’s last row is 50 degrees C at 0.9106K ohms. Under 660 ohms lies past that point, somewhere a working freezer compartment would never go.
While you wait for service
Pressing any button silences the alarm, but it keeps coming back with the blinking fault pattern while the fault remains.
Should food be in danger, relocate it to a second freezer. That is just sensible, whatever code is showing.
Other sensor codes
Code 5 flags this freezer sensor when it reads high instead.
Code 4 applies when every sensor is under 660 ohms.
Code 10 is the matching low-reading fault for the fresh food (PC) sensor.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
