The seven “unreliable appliances” in this warning list are not seven specific models. They are brands, appliance categories, and component choices that Andrew Kuznetsov, president of California repair company Adrium Service Solutions, told Hunker he approaches cautiously. His advice is based on repair experience, not a published failure-rate study.

The practical takeaway is to investigate service access, parts lead times, repair cost, and feature complexity before buying. Kuznetsov does not say every appliance from these brands will fail, and the interview does not identify model years, failure percentages, or a standardized seven-model ranking.

What exactly is on the seven-item warning list?
The headline count is flexible: the Hunker article says Kuznetsov gave “seven. Or 10, depending on how you count.” The list combines two brands with service concerns, two refrigerator cautions, a dishwasher warning covering two brands, a microwave and wall-oven component warning, and a sealed-system connection preference. Treat the sections below as buying cautions rather than universal verdicts.

| # | Appliance or design | What Kuznetsov says to investigate |
|---|---|---|
| 1 | Summit appliances | Parts availability, incorrect shipments, and long delivery delays |
| 2 | Viking appliances | Shorter parts support, marked-up parts, and hard-to-find part numbers |
| 3 | LG refrigerators | Linear inverter-compressor replacements |
| 4 | Samsung refrigerators | Digital inverter compressors and ice makers that can frost the fresh-food compartment |
| 5 | LG and Samsung dishwashers | Control-board costs and unfamiliar features, including zeolite drying |
| 6 | KitchenAid and Whirlpool microwaves and built-in ovens | Inverter-board failures and sensitivity to power fluctuations |
| 7 | Lock-ring fittings in sealed systems | Repairability compared with traditional brazed tubing joints |
Each point below separates the reported experience from what the evidence does not establish.
Are Summit appliances unreliable, or is the problem parts support?
Kuznetsov’s Summit warning is primarily about getting the correct replacement parts, not a claim that every Summit unit is mechanically unreliable. He told Hunker that parts may be unavailable or take “six months for delivery or more,” and that technicians can receive several incorrect parts in succession.
That kind of delay can turn a repairable refrigerator, range, or other appliance into a prolonged outage. A wrong part also creates extra diagnostic visits and labor. Before buying, ask the dealer or manufacturer for the exact service-parts channel for your model, whether the part is currently stocked, and the expected lead time for common items such as electronic controls, pumps, valves, and sealed-system components.
Do not read “six months or more” as a typical lead time for every Summit product. It is Kuznetsov’s description of cases he encountered, and the interview supplies no model-by-model parts database or average.
Why does the expert caution against Viking appliances?
The Viking concern is also serviceability. Kuznetsov says parts support may be shorter, replacement parts can carry a substantial markup, and original part numbers can be difficult to locate. His point is that ownership cost depends on what happens after the warranty period, especially when a specialized control or refrigeration component fails.
For a Viking purchase, obtain the model-specific warranty terms in writing and identify an authorized servicer in your area before installation. Ask who supplies parts, how long discontinued parts remain available, and whether the service company can cross-reference superseded part numbers. A premium purchase price does not by itself guarantee fast repairs.
The interview does not label Viking appliances inherently defective. It reports one repair professional’s experience with parts access and pricing, so compare the exact model and local support network rather than rejecting every product by brand name.

Are LG refrigerators reliable?
Kuznetsov specifically criticizes LG linear inverter compressors. He told Hunker, “I replaced hundreds. I know guys who have replaced thousands of their compressors.” That is a statement about his professional experience and the experiences of colleagues, not a calculated failure rate.
The interview does not specify the affected model numbers, production years, operating conditions, or the total number of units serviced. Consequently, it cannot show how often a compressor fails across the entire LG refrigerator range. A buyer should check the warranty coverage for the compressor and sealed system, how labor is handled after any parts-only coverage, and whether a qualified refrigerator technician serves the area.
Also check the practical consequences of a compressor failure: food loss, temporary storage, diagnostic fees, and the time required to obtain the part. Those questions matter more than a broad online claim that all linear-inverter refrigerators are bad.
Why does the expert warn about Samsung refrigerator ice makers?
Kuznetsov describes two Samsung refrigerator concerns: digital inverter compressors and ice makers that can allow ice to form in the fresh-food compartment. He says repairs may involve major components and can become expensive. For an ice-maker module, he gives an example of “$150 or more, plus labor.” That is his quoted repair estimate, not a current price for every model or location.
Quick wins for a faster PC:
Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →His suggested workaround is a refrigerator without a built-in ice maker paired with a countertop ice maker. That trade-off can free interior space and move the ice-making mechanism outside the refrigerator, but it adds a separate appliance, counter space, cleaning, water handling, and another device that can require service. It does not eliminate the possibility of refrigerator repairs.
Before purchase, inspect the exact ice-maker design, read the warranty exclusions, and ask whether the manufacturer has issued model-specific service guidance. If you choose a countertop unit, plan for drainage, ventilation, and a safe electrical outlet rather than treating it as a maintenance-free substitute.
Are LG and Samsung dishwashers expensive to fix?
Kuznetsov says control-board or control-panel repairs on some LG and Samsung dishwashers can cost more than the appliance itself. He also cautions that new functions may be difficult for technicians to diagnose until they have more service experience, singling out zeolite drying as an example of a feature to investigate carefully.

His warning is about complexity and repair economics, not proof that every dishwasher from either brand will exceed its purchase price in repairs. Feature-rich machines can add sensors, heaters, fans, pumps, boards, and software-dependent controls. Ask the installer which components are covered by the warranty, whether labor is included for electronic failures, and whether a local technician has training and diagnostic access for that model.
Kuznetsov illustrates the ownership trade-off this way: “You can buy Whirlpool — $500 each — every five years three times, or buy a $1500 Fisher & Paykel once.” This is an example from the interview, not an independently calculated life-cycle comparison. Actual service life, repair frequency, water quality, installation, and parts prices vary.
His broader advice is simple: if you cannot find a service path for a new feature, consider a simpler configuration. That may mean fewer specialty drying modes or a control system with readily available parts.
Should you avoid inverter microwaves and built-in ovens?
Kuznetsov says he often sees failed inverter boards in KitchenAid and Whirlpool microwaves and built-in ovens. He recommends considering a conventional design that uses a capacitor and diode instead. His quoted component examples are about “$300” for an inverter board, compared with “$6” for a diode and “$12” for a capacitor.
Those numbers are illustrative component costs from his interview, not a market survey or a guaranteed repair bill. A capacitor-and-diode microwave may provide less sophisticated power control than an inverter design, while an inverter can offer more continuous heating behavior. The choice is therefore a trade-off between desired cooking performance, electronic complexity, and the local cost of replacing the relevant parts.

Kuznetsov also says inverter boards can be sensitive to power fluctuations. Use the installation requirements in the manufacturer’s manual, verify that the circuit is correctly sized, and address recurring voltage problems through a qualified electrician. Do not substitute a surge protector or wiring change for proper diagnosis of an appliance fault.
When comparing models, ask for the price and availability of the magnetron, inverter board or control board, capacitor, diode, and labor. A low component price does not make a repair safe for do-it-yourself work: microwave circuits can retain lethal voltage even when unplugged.

What are lock-ring fittings, and why does the repair expert prefer brazing?
In sealed refrigeration systems, Kuznetsov says he prefers traditional brazing for copper and aluminum tubing over solder-free lock-ring fittings. His exact preference is: “Old-school brazing is the best quality connection for copper and aluminum tubing.” He also says, “I would prefer to buy a fridge without these fancy-shmancy lock-ring fittings.”
This is a technician’s repair preference, not an independent finding that every lock-ring connection leaks or violates a standard. The interview does not compare leak rates, installation quality, or long-term performance. If a refrigerator uses a particular fitting system, ask the authorized service company whether it has the tools, training, and replacement fittings for that design.
Do not attempt to open or recharge a sealed system without the required certification, recovery equipment, and safety procedures. Refrigerant work involves pressure, electrical hazards, and environmental rules that vary by jurisdiction.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which alternatives does Kuznetsov mention?
In the interview, Kuznetsov speaks favorably of Whirlpool cooktops, Wolf ranges, Toshiba or Sharp and other Japanese-brand microwaves, LG washers and dryers, Samsung dryers, Sub-Zero refrigerators, and Perlick wine refrigerators. These are his reported preferences, not independently verified rankings.
He also discusses wine refrigerators costing about $3,400 at the entry level, with some models priced above $10,000. Those figures are quoted in the Hunker article without a market-wide survey or specific model list, so use them only as an indication that specialty refrigeration can require a substantial budget.
The useful lesson is not to swap one blanket brand judgment for another. For any alternative, verify the exact model’s warranty, service coverage, parts supply, installation requirements, and repair history in your region.

- Record the exact model number. Reliability, components, and warranty terms can differ within one brand and product family.
- Confirm warranty scope. Separate parts-only coverage from labor, sealed-system, compressor, control-board, and service-call coverage.
- Call a local authorized servicer. Ask whether technicians are trained on the model and which repairs they perform in-house.
- Check parts access. Request current availability and an estimated lead time for the main board, compressor, ice-maker module, pump, valve, and heating components.
- Price the likely repair. Compare diagnostic fees, labor, travel, and the part—not just the advertised component price.
- Count the complexity. Extra sensors, specialty drying systems, inverter electronics, and proprietary fittings can add failure points or require specialized training.
- Plan for downtime. Refrigerators and cooking appliances can create food-safety, storage, or meal-preparation problems while waiting for parts.
- Keep installation compliant. Correct voltage, ventilation, drainage, grounding, and sealed-system work protect both safety and warranty eligibility.
These checks cannot predict a failure with certainty. They reveal whether a failure would be practical and affordable to resolve.
What should you take from this warning list?
The strongest conclusion is about repairability, not a universal “avoid” verdict. Kuznetsov’s Summit and Viking objections concern parts support; his refrigerator and dishwasher comments reflect reported repair experience without failure-rate data; and his microwave and fitting preferences concern component design and service technique.
Use the list to ask better questions before committing to a model. A product with a convenient feature may still be a sensible purchase if parts, labor, warranty coverage, and qualified service are readily available. Conversely, a highly rated appliance can become a poor fit when a critical part is unavailable locally or a repair costs close to replacement.
Frequently Asked Questions
Do these warnings apply to every model from the named brands?
No. The interview does not provide a complete model list, production years, or brand-wide failure rates. Treat each point as a reason to investigate the exact model and local service network.
What should I ask a dealer about appliance parts?
Ask who supplies replacement parts, whether common electronic and refrigeration components are currently stocked, and the expected lead time if a part is back-ordered. Get the answers for the exact model number rather than the product family.
Is a countertop ice maker safer than a refrigerator ice maker?
It is a different maintenance and ownership choice, not a guaranteed reliability upgrade. It can preserve refrigerator space and isolate the ice-making mechanism, but it needs its own cleaning, water handling, electrical connection, and eventual repairs.
Are inverter microwaves always a bad purchase?
No. Kuznetsov’s criticism concerns repair cost and board complexity in the cases he sees, not proof that every inverter microwave fails. Compare the cooking behavior you want with local service capability and the cost of the relevant replacement parts.
