nA
Liebherr nA on a fridge-freezer: freezer warmed during power cut
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
On Liebherr fridge-freezers, nA means the freezer got too warm during a power failure or interruption. Press Alarm to see the warmest temperature reached, check the food, never refreeze anything that has thawed, and make sure the plug and fuse are fine.
Safety first
Stop and check this first
- Do not open panels or touch the cooling circuit: the refrigerant is named on the rating plate, and any leak or repair is a job for customer service.
- Liebherr is clear that spoiled food must not be eaten and thawed food must not be refrozen after an nA warning.
Safe checks you can perform
- Read the warmest temperature with the Alarm button
- Check the food and do not refreeze it
- Check the plug and the socket fuse
- During a long outage, protect the frozen food
Leave these tasks to a qualified professional
- Do not attempt this professional task: Temperature measurements if nA returns without outages
- Do not attempt this professional task: Electrician check of the socket circuit
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Temperature measurements if nA returns without outages
What they doIf nA keeps appearing when the power has not failed, an authorised Liebherr technician checks that the compressor and fan start and measures the real temperature in both compartments over a cycle.
They must show youthe measured freezer and fridge temperatures and the compressor running.
In writingthe code seen, the measured temperatures, any part replaced and the test result.
Electrician check of the socket circuit
What they doWhen the socket fuse trips or power fails only at that outlet, a qualified electrician inspects the circuit and the voltage reaching the fridge-freezer.
They must show youthe voltage measured at the socket and the state of the fuse or breaker.
In writingthe measured voltage, the cause of the cut found and what was repaired.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Read the warmest temperature with the Alarm button
- Who:
- you, using the Alarm button on the fridge-freezer panel.
- How:
- with nA on the display, press the Alarm button once. For about 60 seconds the display shows the warmest temperature the freezer reached during the outage, then it returns to the current freezer temperature. Pressing Alarm again clears that reading early.
- Result that matters:
- you know how warm the freezer got, so you can decide which food needs checking.
- If the reading stayed below freezing:
- still check the food as Liebherr instructs.
- If the reading went above freezing:
- treat anything soft as thawed.
- Evidence to keep:
- photo of the display showing the warmest temperature before it disappears.

Check the food and do not refreeze it
- Who:
- you.
- How:
- open the freezer and go through the food item by item. Liebherr asks you to check its quality, not to eat anything spoiled and not to refreeze anything that has thawed. Close the door as soon as you are done so it can cool down again.
- Result that matters:
- doubtful food removed and the door shut again.
- If packs are soft or the frost on them has melted:
- do not refreeze them.
- If all the packs are still frozen solid:
- leave them inside and watch the temperature fall.
- Evidence to keep:
- a list of what you threw away or used up and the date of the outage.

Check the plug and the socket fuse
- Who:
- you, without taking anything apart.
- How:
- make sure the fridge-freezer plug is fully pushed into the wall socket and that the fuse or breaker for that circuit has not tripped. If the appliance was off, switch it on with its On/Off button and confirm the temperature display lights up.
- Result that matters:
- the appliance powered and its display lit.
- If the plug was loose or the fuse had gone:
- fix it and wait for the temperature to drop.
- If the fuse trips again:
- stop resetting it and have an electrician check that circuit.
- Evidence to keep:
- photo of the fuse board and the plug after checking.

During a long outage, protect the frozen food
- Who:
- you.
- How:
- while the power is still off, keep the appliance closed. If the outage lasts, Liebherr suggests placing dry ice on top of the food or moving it to another working freezer. Do not refreeze anything that has thawed.
- Result that matters:
- frozen food protected for as long as the outage lasts.
- If power comes back soon:
- keep the door shut and check the food with the Alarm button.
- If the outage goes on for a long time:
- move the food to another freezer.
- Evidence to keep:
- start and end time of the outage, if you know them.

What it means
The Use and Care Manual for the Liebherr HC 1011/1060 HC 1001/1050 integrated fridge-freezer (document 7082698-00) says nA shows when a power failure or power interruption let the freezer temperature rise too high over the last hours or days. Once power returns the appliance keeps its last setting. Pressing Alarm displays the warmest temperature reached for about 60 seconds. Newer Liebherr models show the same event as a symbol instead. Seeing nA does not, on its own, prove that the compressor or any other component is faulty.

Symptoms and causes
Probable causes · in order
- Mains power cutCommon
A supply interruption stops the compressor and the freezer warms up; Liebherr flags it with nA once power is back.

- Loose plug or blown socket fusePossible
The manual lists a plug not properly inserted in the wall socket and a faulty socket fuse as reasons the appliance stops working.

- Appliance switched off for a whilePossible
If the fridge-freezer was off for hours or days, the freezer loses cold just as in a blackout and the warning appears afterwards.
