The short answer
A Fisher & Paykel refrigerator showing a fault code or ignoring its settings is reporting a condition rather than announcing a dead board, and boards are the least common cause. Record the code and the compartment temperatures first, then rule out the door switch, the sensor and the supply, because each of those makes the control behave exactly like a failed one.
Causes, ranked for this Fisher Paykel refrigerator
- A sensor reading out of range — Why: The board acts on what its sensors report, so a failed or disconnected sensor produces a fault code and wrong behaviour while the control itself is working perfectly.
- Door switch or its wiring — Why: A stuck switch tells the control the door is open, which suppresses cooling functions and raises alarms, and the wiring runs through a hinge that flexes at every opening.
- Supply problems rather than the appliance — Why: A shared socket, an extension lead or a dropout resets the control mid-operation, which reads as a board that loses its settings.
- A condition the code is correctly reporting — Why: Codes for defrost, fan or temperature faults name a real problem elsewhere; clearing the code without reading it discards the only diagnostic information you had.
- The control board itself — Why: Last. Boards do fail, but every cause above imitates one and each is far cheaper to investigate, so this is a conclusion rather than a starting point.
What to check, in order
- photograph the code and note exactly when it appears. — Because: the code is the diagnosis and a reset erases it permanently.
- measure both compartments with an independent thermometer. — Because: it establishes whether the appliance is actually failing to cool or only complaining.
- check the door switches by watching the interior light and any alarm. — Because: a stuck switch produces control-like behaviour and is quick to eliminate.
- confirm the unit is on its own socket with no extension lead. — Because: supply dropouts reset a control repeatedly and look exactly like a dying board.
Checks you can safely do yourself
- Photograph the display, write down the code and record when it appears relative to door openings, defrost or filling the unit. — Tools: a phone camera — Time: several minutes
- Put an independent thermometer in each compartment and read them after several hours rather than immediately. — Tools: two appliance thermometers — Time: an afternoon, mostly waiting
- Open and close each door slowly, watching the interior light and any alarm to confirm the switches respond. — Tools: none — Time: several minutes
- Confirm the unit is plugged directly into its own socket, and check the breaker for that circuit. — Tools: a torch — Time: several minutes
- Only after recording everything, switch the unit off at the breaker for a few minutes and back on to see whether the code returns. Stop here: sensors and boards need a meter. — Tools: none — Time: several minutes

Safety

Kill power at the breaker before touching any wiring or removing a cover, and never chip frost inside with a metal tool, because the liner and the evaporator behind it puncture easily. If a code appears alongside a burning smell or a tripping breaker, stop using the appliance and treat it as an electrical fault.
Where the owner fix ends
Recording the code, measuring temperatures, checking doors and confirming the supply are owner work. Call a technician when a code returns after a power cycle, when a compartment misses the safe temperatures quoted above, and when settings will not hold on a confirmed clean supply, since sensors, harnesses and boards all need metering.
