Code 3: all temperature sensors are above the normal resistance range at once.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so 3 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 resistance of every temperature sensor is outside the normal range, above 45K ohms.
Sensor codes usually name a single sensor, but code 3 covers the lot. Every temperature sensor reads outside its proper range, over 45K ohms. The remedies in the manual lead to the shared connector and to the power module, never to an individual sensor.
Remedies, in the manual’s sequence
Primary: inspect the 6 way RAST connector on the power module.
Secondary: reterminate that connector.
Tertiary: fit a new power module.
Putting 45K in context
A thermistor table in the manual begins at -30 degrees C, where a sensor ought to show roughly 25.17K ohms, and finishes at 50 degrees C with 0.9106K ohms. Warmer means lower resistance. A reading above 45K falls beyond the cold edge of the table, miles from what a healthy freezer sensor reports.
Leave it to a technician
The connector sits on the power module. Owners can mute the alarm with a button and jot down the blinking LED pattern; there their part ends.
Codes alongside this one
Code 4: every sensor again, but with readings below 660 ohms.
Code 1: a power module that did not pass its self-test at the last start-up.
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.
