The Refrigerator Secret: Kenmore vs. LG in 2026
1. The Core Angle: Software Locking
The secret lies in the firmware. This is the code that manages how the internal motors and sensors interact. In 2026, original LG refrigerators are constantly connected to the internet, receiving updates that fix bugs and optimize the motor's performance.
Kenmore units, however, are often software-locked. They are stuck with older software versions that never change. While an LG unit might get a 2026 update to improve its cooling efficiency, the Kenmore is still running on code from 2023 or 2024. This lack of updates forces the parts to work harder, leading to earlier mechanical breakdowns.
2. What is rebadging?
In the appliance industry, this is known as rebadging. It is like taking a Toyota engine and putting it into a Suzuki frame. LG builds the engine (the cooling system) in South Korea, but Sears (Kenmore) builds the frame (the cabinet, shelves, and doors). When something goes wrong, you are left with a hybrid machine that neither company fully wants to support.
3. Technical Specifications: The Voltage Spike Mystery
The heart of these units is the compressor. In 2026, these machines use inverter frequency control to manage speed and save energy. However, the software logic differs between the two brands.
Frequency and Control Logic
A modern LG compressor changes speed based on cooling demand, measured in hertz (Hz).
- LG Logic: The system is designed to run smoothly between 30 Hz and 90 Hz. It uses smart AI to stay at a calm 30 Hz whenever possible to prevent wear.
- The Kenmore Problem: Because of the older firmware, the Kenmore board often mismanages the power signal. The Kenmore board sends a 5V DC signal to the compressor, but because of the old firmware, it often spikes to 7V unnecessarily, frying the controller and putting massive stress on the motor.
The 450W Defrost Factor
Both brands use a heater to clear ice from the freezer coils, drawing roughly 450W of power. LG uses Adaptive Defrost, which only runs the 450W heater when sensors detect ice. Kenmore often uses a basic timer that fires the 450W element every 8 hours, regardless of ice buildup, which wastes significant electricity and money over time.

5. 2026 Comparison Table
| Feature | Original LG (2026) | Kenmore (LG-Made) |
|---|---|---|
| Retail Price | $2,400 to $4,500 | 1,500 to $3,200 |
| Software Status | Active OTA Updates | Software-Locked |
| Controller Signal | Stable 5V DC | Unstable 5V to 7V Spikes |
| Parts Access | Direct & Plentiful | Low (Sears Dependency) |
| Resale Value | ≈ 30% (5 Years) | ≈ 10% (5 Years) |
6. The App Store Metaphor
Buying a Kenmore-LG is like buying a high-end smartphone with no app store. The hardware is beautiful, the screen is sharp, and the battery is strong. However, because you are locked out of the manufacturer's updates, you never get the software patches that fix bugs or save battery. The world moves forward with 2026 technology, while your refrigerator is stuck in 2023 until it eventually burns out.
7. The Repairman’s Verdict
Independent technicians overwhelmingly prefer original LG units. LG manuals are easily accessible online, allowing techs to diagnose problems in minutes. Kenmore uses mystery model numbers (usually starting with 795) that require a complex conversion process just to identify the parts. Many local shops now refuse to work on Kenmore units because the software ID barriers make them a headache to fix.
Expert FAQs
1. Can I update my Kenmore software to LG software?
No. The control boards are programmed with unique IDs. Attempting to flash LG software onto a Kenmore board usually results in a software ID mismatch that disables the machine entirely.
2. Why does the Kenmore price look so much better?
The initial discount is a trap. Because Kenmore units are orphaned by the manufacturer, they lack the AI-driven cooling that protects the compressor. You save $500 today, but you risk spending $2,000 on a new fridge in three years.
3. Does the voltage spike really matter?
Yes. Consistent 5V to 7V spikes in the control signal degrade the electronics. While a stable 5V keeps the compressor running for a decade, these spikes act like mini-surges that eventually fry the main controller board.
4. Is the Kenmore warranty reliable?
On paper, it looks standard. In practice, owners get stuck in a support loop. Sears technicians often wait weeks for LG-made parts that LG prioritizes for its own branded customers first.
