Fisher & Paykel active smart fridge keeps beeping for no apparent reason, while door closed

perhaps the reed switch (the magnetic switch to tell the PCB the door is open/closed).

With F&P fridges, the amount of beeps will indicate the error code which relates to which component is faulty.

check the thermostat setting for the compartment
it may not be set low enough so the alarm goes off when the compartment temperature reaches or exceeds that setting
some fridges have a system whereby if the door is open too long then it notifies the user to close the door

Does the beeping start immediately or does it follow the designed timing as stated on page 12 of the manual? You would have to check with the manufacturer to see if the feature can be disabled. Page 12 of Fisher Paykel Refrigeration User Guide ManualsOnline com

Your fridge is telling you there is a fault, i'd say one of the 2 fans are not working. If everything is freezing in the bottom of the food compartment then the upper fan is faulty. You have to remove the shelves & remove the rear panel, the fan is in the shute at the bottom, remove, repair the broken wire or replace. Make sure unit is unpluged.

Do you see any ice buildup on the back wall of the freezer or behind it?

well you could try to unplug it for about 10 minutes or more to reset it. if not the door button has probably gone bad

Generally either the fridge of freezer internal fan motor isn't working. The beeping is telling you there is something wrong. You can check this with a strong magenet on the door switch. Leave one door closed and put the magenet on the door switch and the light will go off. Then feel the back of the internal wall and see if you can feel air movement. Then check the other compartment the same way.

will need someone with the correct diagnostic equipment to tell you whats wrong

If the cabinet is warm inside it is a failed circulation fan, failed defrost causing the evaporator to freeze up, or it needs a refrigerant gas top up.

Beeping is just an alarm. It may be because of the more serious issues listed above but can also be caused by a failing door gasket, the door being left ajar (kids are famous for this) or the door has been left open too long deciding what to have for dinner.

I hope that answers all 8 of you :>D

I would reset the module. Open the fridge door, keep the freezer door closed, then press the mode button (located on the display panel. This will re initiate the electronics
