Code 12 reports excess combined current on the ambient heater and both fans.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so 12 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
The current measured for the ambient heater, PC fan and FC fan is higher than expected.
What code 12 reports
Too much electrical current is flowing, the fridge has found, through its low ambient heater and the pair of fans. It is the reverse of code 11, where the current is too low.
The manual’s sequence
The 6-way connector at the power module is checked by a technician.
The connector is reterminated.
Only then is the module replaced.
The code covers the three loads at once, so it does not name one failing fan or heater. If just one part is to blame, it has a code of its own in the manual: the heater is 14, the PC fan 16, the FC fan 18.

What owners should and should not do
Live wiring sits inside the cabinet when current is the problem, so panels stay on and connectors stay untouched. The only owner move is to cut the power for a few seconds, which restarts the self-test. If the code is back, stop.
The alarm is silenced by a control button, though the code returns once eight seconds of ordinary display have gone by.
A code 12 that keeps returning is worth a call to (310) 872-1939 for Fisher & Paykel refrigerator repair in Los Angeles. Quote the model number and code, and say if a fan was noisy or buzzing before the alarm.
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.
