Fisher & Paykel Refrigerator Code 6: Freezer Sensor Under 660 Ohms

Code 6 is the low-resistance half of a pair. The freezer (FC) sensor reads below 660 ohms, and code 5 is the same sensor reading too high. The Active Smart service manual lists both together.

Sensor codes at a glance

What the low figure means

A thermistor loses resistance as it gets warmer. The manual’s table ends at 50 degrees C with 0.9106 kilohms, so anything below 660 ohms is lower than every temperature listed, and the control rejects it. Whether the wiring is shorted or the sensor has failed is not stated; the manual says only what to check.

Steps from the manual

1. Inspect the connection at the power module.
2. With the connection good, replace the sensor.

Worth noticing at home

• Check whether the freezer holds its temperature; ice cream and frozen meat show a problem first.
• Remember whether the alarm began at power-up or at a random moment, and pass that on when you call.
• See if code 6 stays alone on the display or alternates with other codes.

Why owners should not open it up

The freezer sensor wiring travels inside the cabinet to the power module, which carries mains-powered electronics. For code 6 the manual lists technician steps only, so nothing outside can be cleaned, tightened or adjusted. A button press silences the alarm, and cutting power for a few seconds resets it.
