Fisher & Paykel Freezer 12 Error Code

Code 12 mirrors code 11, but with excess current. The power module adds up the draw of the LAH heater, the PC fan and the FC fan, and finds it above the expected amount.

Which parts?

Three: the heater that works at low ambient temperature, the fresh food fan and the freezer fan, all metered as one group. Under this code the manual does not name the culprit among them. For that you look to codes 14, 16 and 18, which pick out the heater, the PC fan and the FC fan one by one when any of them pulls too much.

Service order in the manual

1. Inspect the 6-way fan/LAH RAST connector at the power module.
2. Reterminate it.
3. Finally, fit a new power module.

How to read the pattern

The number appears in binary on the LEDs. Each lit LED has its value and the values are summed. In the manual’s own sample, 2 and 16 give 18, so code 12 is whichever pattern totals twelve.

Timing of the reading

Powering up, or closing a door while powered, starts a self-test of 20 seconds. A door opened during that window can alter what the display shows. Keep the doors shut, give it time to settle, and take the code from the display after the test ends.

Is the alarm a hazard?

No hazard is described in the manual, only an audible alarm, a blinking bottom LED and the pattern. Because this is a fault of excess current, though, it makes sense to leave the unit unplugged if you notice heat, a burnt smell or damaged wiring, and to tell the person you phone.

Close relatives

• Code 11: under-current for those three loads.
• Code 14: the heater by itself, over-current.
