Fisher & Paykel ActiveSmart Refrigerator Code 22: Second Fresh Food Sensor Cold

What Code 22 means

On original E-series ActiveSmart refrigerators such as the E522BRXU, Code 22 means the second fresh food sensor, PC2, reads above 45K ohms, shown as PC2 sensor cold. That is an open reading from the sensor or its wiring. The control loses part of its picture of the fresh food compartment. The LCD or beep pattern shows the code. The accuracy of the readings suffers.

Common causes of Code 22

PC2 sensor unplugged or broken
Damaged wire to PC2
Loose connection at the power module

✓ One safe check you can try

1. Unplug the refrigerator for five minutes and restart. 2. Make sure food does not block the fresh food vents. 3. Check the door seal closes completely. 4. If Code 22 stays, call us. Avoid opening the doors often. Note anything odd about shelf temperatures so we can pass on what you saw before the visit.

! Why to stop there

The sensor wiring runs behind the liner.
A false cold reading can make the control run warmer than you set.
We test the sensor and the connection, with a written quote first.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Why is it called PC2?

It is the second sensor in the fresh food compartment, alongside the main PC sensor. It is one of two sensors in the fresh food area. Ask us about it.

Will the fridge still cool?

Usually yes, because the main sensor keeps working, but accuracy can suffer. The fridge usually keeps cooling, though shelf temperatures may drift a little. A few degrees of drift is common.

What is replaced?

The PC2 sensor or its connection. The price is in writing first, and our work has a 30-day workmanship warranty. The price is in writing before work begins.
