Short answer: the Panasonic NR-CY55CGKAU can make sense if you want a wide, freestanding French-door refrigerator and find a well-maintained unit at a sensible price. For an honest capacity comparison, use its official 494 L rated volume—not the 551 L figure used in Panasonic marketing and some listings. The model is discontinued or no longer available through the retailers identified for this review, so warranty status, parts access, door clearance and actual cooling performance matter more than its feature list. Panasonic lists ECONAVI sensing, inverter control, Prime Fresh+ soft freezing, Blue Ag treatment and a Fresh Safe crisper, but there is no independent laboratory evidence here to verify claimed energy, hygiene or food-life benefits.
What is the Panasonic NR-CY55CGKAU?
The NR-CY55CGKAU is a freestanding refrigerator with a black-glass exterior, two upper refrigerator doors and lower freezer storage. Panasonic describes it as a “551L French Door Refrigerator,” while the operating instructions identify the appliance’s rated volume under AS/NZS 4474:2018 as 494 L. Those figures describe different labeling conventions, so buyers should not treat them as two separate compartments or add them together.
Its layout is aimed at households that want refrigerator food at eye level and a broad freezer section below. The cabinet is substantially wider and taller than a typical top-freezer appliance, and the black-glass finish is a visual feature as well as a practical consideration: fingerprints and door clearance are easy to overlook when inspecting a used unit.
How much usable capacity does the NR-CY55CGKAU really have?
Use 494 L as the primary comparison figure. Panasonic’s 2019 operating manual gives the rated volume as 494 L, split between 356 L for the refrigerator compartment and 138 L for the freezer. The 551 L label appears on Panasonic’s archived product page and in distributor and auction material, but those sources do not replace the formal rated-volume figure.

| Capacity measure | Published value | How to interpret it |
|---|---|---|
| Total rated volume | 494 L | Official AS/NZS 4474:2018 rated volume in Panasonic’s 2019 operating instructions; use this for comparisons. |
| Refrigerator compartment | 356 L | Rated fresh-food compartment volume. |
| Freezer compartment | 138 L | Rated freezer volume. |
| Marketing/model-family label | 551 L | Used on an archived Panasonic page and in some sales listings; do not substitute it for the rated figure. |
This distinction matters when comparing cabinet sizes, removal routes and prices. A listing that says “551 L” may be referring to the product family or a different measurement convention rather than the standardized usable volume. Ask the seller for a photograph of the rating plate and the manual if the advertised capacity is the deciding factor.
What are the NR-CY55CGKAU’s key specifications?
The following figures come from Panasonic Corporation’s 2019 operating-instructions specification table. Dimensions are external cabinet dimensions, not the minimum cavity or delivery space.
| Specification | NR-CY55CGKAU figure |
|---|---|
| Rated total volume | 494 L |
| Refrigerator volume | 356 L |
| Freezer volume | 138 L |
| External dimensions (W × D × H) | 770 × 743 × 1714 mm |
| Net weight | 89 kg |
| Refrigerant | R600a |
| Cooling type | Non-frost |
| Blue Ag treatment | Yes |
| Installation connection | 10A plug and lead; no plumbing connection required, according to the retailer listing. |
The 89 kg net weight is significant for stairs, lifts and delivery trucks. A refrigerator that physically fits through the front door may still be impractical if the route includes a narrow landing or a turn that cannot accommodate a 770 mm-wide cabinet.

Pick the symptom - the matching free tool is one click away.
What features does Panasonic advertise, and what is actually verified?
Panasonic’s product material presents several convenience and food-storage systems. They are manufacturer claims rather than independently measured results; no independent laboratory measurements of energy use, temperature uniformity, antibacterial performance or food-life extension were located for this model.
ECONAVI intelligent sensing
ECONAVI is described as a sensing system that adjusts operation based on usage conditions. In practical terms, it is intended to avoid running the compressor at a fixed maximum level when the refrigerator is opened less often. The available documentation does not establish a measured annual-energy figure or a verified saving percentage for the NR-CY55CGKAU, so treat ECONAVI as a control feature, not a guaranteed reduction on your electricity bill.

Inverter control
Panasonic lists inverter control alongside ECONAVI. An inverter compressor can vary its operating speed instead of relying only on repeated full-power starts, which may help with temperature stability and sound characteristics. The model-specific documents supplied for this review do not provide an independent noise measurement, energy test or long-term compressor-failure rate.
Prime Fresh+ soft freezing
Prime Fresh+ is a dedicated soft-freezing mode intended to keep selected food colder than the refrigerator compartment without making it as hard as conventional freezer storage. It is useful for foods you expect to cook soon, because the goal is easier portioning and shorter thawing. Exact food-safety limits, recommended storage times and measured temperature performance should be confirmed in the manual before relying on the mode for a particular ingredient.
Blue Ag treatment
The specification table confirms Blue Ag, and Panasonic presents the system as a hygiene feature. The available evidence does not include a third-party antibacterial test for this exact refrigerator or proof that it extends food life. It should therefore complement ordinary cleaning and safe food handling rather than replace them.
Fresh Safe crisper
The Fresh Safe compartment is intended to retain moisture around produce. That design may help reduce drying compared with an open shelf, but no independent measurement of humidity or produce-life extension is available for this model. Keep the compartment within its recommended load and avoid blocking vents, since a tightly packed drawer can defeat any circulation benefit.
Will the NR-CY55CGKAU fit your kitchen?
The cabinet itself measures 770 mm wide, 743 mm deep and 1714 mm high. E&S lists a suggested cavity of approximately 870 mm wide, 843 mm deep and 2014 mm high. The difference provides room for door movement, ventilation and installation—not spare storage space—so do not design a tight enclosure around the cabinet dimensions alone.

Check more than the opening width
- Door swing: French-door panels need clearance to open far enough for shelves and drawers to be removed. Measure adjacent walls, tall cabinets and island benches.
- Depth and rear ventilation: Allow the retailer’s suggested depth rather than pushing the cabinet flush against the wall. Confirm the required rear and side gaps in the manual.
- Top clearance: The suggested cavity height is about 2014 mm, considerably above the 1714 mm cabinet height. This helps with ventilation and leveling but does not guarantee that the doors can be lifted off in your room.
- Delivery path: Measure the front door, hallway, stairwell, lift and every turn. Include packaging and the 89 kg net weight when arranging delivery.
- Power: The retailer specifies a 10A plug and lead. Use a properly earthed outlet and avoid extension leads unless a qualified installer confirms they are suitable.
- Water supply: No plumbing connection is required according to the retailer listing, so installation does not depend on a nearby water line.
Before buying a used appliance, open both refrigerator doors and the freezer fully while it is in the proposed position. A cabinet can fit between walls yet leave insufficient room to remove a crisper or freezer drawer.
Is the Panasonic NR-CY55CGKAU discontinued?
Yes, availability is a concern. E&S marks the exact model “No longer available,” and ProductReview labels it discontinued. That does not prove that every unit is unusable, but it means new-stock warranty coverage, replacement shelves, control boards and seals may depend on remaining inventory or third-party supply.
Availability is time-sensitive, especially in the used and reconditioned market. Before paying, obtain written confirmation of the seller’s warranty, the return period, who performs service, and whether model-specific parts can still be ordered in your country. A low purchase price is less attractive if a failed fan or door seal leaves a large appliance unusable.
Is it reliable, and what problems have owners reported?
There is not enough evidence to calculate a failure rate. ProductReview contains one owner report alleging inadequate cooling and delayed technician follow-up. That account is worth investigating, but one report is not a representative survey and cannot establish that the model has a systemic defect.
No independent reliability study, energy test or statistically representative owner dataset was identified. As a result, the sensible approach is condition-based buying: inspect the exact unit, verify that it reaches and holds stable temperatures, and judge the seller’s support in addition to the Panasonic name.

Cooling concerns to investigate
- Ask how long the appliance has been running continuously and whether it was recently transported.
- Look for excessive frost, warm food, unusual cycling or a compressor that never appears to rest.
- Check that interior fans operate when the doors are closed and that vents are not blocked by containers.
- Request a written remedy if the unit fails to maintain temperature during the return period.
Service-delay risk
The reported delayed technician response makes the service channel part of the purchase decision. Record the seller’s phone number, warranty administrator and escalation procedure before delivery. For a discontinued model, ask whether the technician can obtain the correct control electronics and door components rather than assuming a generic repair is possible.
How should you buy a used or reconditioned NR-CY55CGKAU?
A hands-on inspection is more valuable than a listing headline. Use this checklist before committing:
- Confirm identity: Photograph the model and serial labels and make sure they read NR-CY55CGKAU, not a visually similar Panasonic model.
- Reconcile capacity: Treat 494 L as the rated comparison figure and ask why the seller uses 551 L if that appears in the advertisement.
- Inspect the cabinet: Look for black-glass cracks, deep dents, corrosion, loose trim and door hinges that do not sit level.
- Test the seals: Close each door on a sheet of paper. Noticeable gaps or a seal that slips out easily can cause warm spots and excess running.
- Test storage hardware: Slide every drawer, shelf and freezer basket through its full travel. Replacement parts may be difficult to source after discontinuation.
- Verify cooling: Have the unit powered before collection or delivery and check temperatures over an extended period rather than judging by a cold exterior.
- Review paperwork: Request the original manual, purchase receipt, service invoices and any previous fault reports.
- Get terms in writing: State the warranty length, return window, delivery damage process and who pays for a failed repair.
- Plan transport: Confirm that the delivery team can move an 89 kg appliance through your measured route and position it without damaging the doors.
What should you compare before choosing this refrigerator?
Because the exact model is discontinued, compare it with currently supported French-door refrigerators using standardized, practical criteria rather than headline capacity alone.
| Comparison question | Why it matters for the NR-CY55CGKAU |
|---|---|
| What is the rated usable capacity? | Use 494 L for an apples-to-apples comparison; do not mix it with a 551 L marketing label. |
| What are the external dimensions and clearance needs? | The 770 × 743 × 1714 mm cabinet still needs space for doors, ventilation and delivery. |
| How is storage divided? | This model allocates 356 L to the refrigerator and 138 L to the freezer; choose a different split if your household freezes more food. |
| Is cooling non-frost and controllable? | Non-frost operation reduces manual defrosting, while actual temperature stability should be verified independently. |
| Does installation require plumbing? | This model uses a 10A plug and lead and does not require a water connection, which can simplify placement. |
| Are warranty and parts available now? | Discontinued status increases the importance of current support, written warranty terms and parts access. |
| Is there independent performance evidence? | For this model, published independent measurements of energy, noise, cooling uniformity and hygiene performance were not found. |
Who is the NR-CY55CGKAU best suited to?
It may suit you if:
- You need a large refrigerator compartment and prefer French-door access.
- Your kitchen can accommodate the suggested cavity and the full door swing.
- You do not want to run a water line to the refrigerator.
- You are buying a demonstrably healthy used unit with a clear return or warranty arrangement.
- You value storage modes such as Prime Fresh+ and a humidity-oriented produce drawer, while understanding that their benefits are manufacturer claims.
Look elsewhere if:
- You need guaranteed new-stock warranty coverage or readily available manufacturer parts.
- Your installation path cannot safely handle a 770 mm-wide, 89 kg appliance.
- You require independently verified energy, noise or temperature-performance data before purchase.
- You want a narrower cabinet or a different refrigerator-to-freezer balance.
How do you install the NR-CY55CGKAU safely?
- Measure the complete route and the final cavity, including the approximate 870 mm width, 843 mm depth and 2014 mm height suggested by the retailer.
- Protect floors and door edges during movement; do not drag the 89 kg cabinet across finished flooring.
- Position the refrigerator with the ventilation clearances specified in the operating instructions.
- Level the cabinet so both French doors close evenly and the drawers travel without rubbing.
- Connect the supplied 10A plug and lead to a suitable earthed outlet. No water connection is needed.
- Allow the refrigerator to stabilize before loading it heavily. Follow the manual’s transport and start-up guidance, especially if the unit was carried on its side.
- Check door seals, interior lighting, fans and each storage mode before accepting delivery or ending the return period.
What maintenance and troubleshooting should owners plan for?
Non-frost cooling removes the routine of manually scraping ice, but it does not eliminate maintenance. Keep door seals clean, avoid covering internal vents, clean spills promptly and leave enough space around food for air circulation. Follow Panasonic’s manual for cleaning agents and any serviceable filters or panels rather than improvising with abrasive products.
Quick wins for a faster PC:
Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →If food is warmer than expected
- Confirm that a door is closing fully and that a drawer or container is not obstructing the seal.
- Check whether the cabinet was recently loaded with a large amount of warm food or has been opened repeatedly.
- Make sure vents are not blocked and that the refrigerator has the required clearance.
- If temperatures remain unstable, stop relying on the appliance for perishable food and contact the seller or an authorized technician.
If the appliance is noisy
Inverter refrigerators can change compressor speed, and fans may run during cooling or defrost cycles. A new scraping, repeated clicking or vibration that continues after leveling deserves service attention, particularly on a discontinued appliance where a prompt diagnosis may affect your return rights.

What is the final buying verdict?
The NR-CY55CGKAU is a capable-looking, large French-door refrigerator whose meaningful comparison capacity is 494 L, divided into 356 L of refrigerator space and 138 L of freezer space. Its 770 mm width, non-frost cooling and no-plumbing installation can work well in a suitably planned kitchen, and the advertised storage features may appeal to households that use soft-freezing and produce drawers.
However, discontinued status changes the risk calculation. The model has limited independent performance evidence, one owner report raises cooling and service-response concerns, and parts or warranty coverage may be difficult to verify. Buy only after checking the exact unit’s cooling, seals, doors, delivery route, support terms and parts availability; otherwise, a current model with documented after-sales support is the safer choice.
Frequently Asked Questions
Is R600a refrigerant safe in this refrigerator?
R600a is a hydrocarbon refrigerant used in sealed household systems and is flammable. Do not pierce tubing or attempt a refrigerant repair yourself; use a qualified refrigeration technician and follow the manual’s handling instructions.
Can the NR-CY55CGKAU doors be reversed?
The available specifications do not establish whether the French-door hinges are reversible. Ask Panasonic support or the seller to confirm this for the exact serial-number variant before planning a tight installation.
What paperwork should I request when buying one privately?
Ask for the model and serial numbers, original purchase receipt, operating manual, service invoices and a written return or warranty agreement. Those records help establish age and may reveal previous cooling or control-board repairs.
How can I check a used unit for a hidden cooling fault?
Inspect it while powered, check that fans and doors operate normally, and monitor interior temperature over an extended period rather than judging by touch. Put any temperature or return promise in writing before collection, because discontinued support can make later disputes harder to resolve.
