Kenmore 795.74025.411: Complete Cooling Failure from Failed LG Linear Compressor in Memorial, TX
📞 Call (346) 512-3688🔧 Performed by Serhii T.
The Problem
- •Refrigerator completely stopped cooling, both fresh food and freezer sections warm
- •Unit runs continuously but produces no cold air
- •Food spoiling within 24 hours despite the refrigerator appearing to operate normally
🔍 Diagnosis
When I arrived at the home in Memorial, the customer told me her Kenmore had stopped cooling entirely. The unit was only 5 to 6 years old and she was very attached to it. I checked the condenser coils first and they were clean. The evaporator fan was spinning, the start relay was intact, and the control board showed no fault codes at that moment. I connected my manifold gauge set to the sealed system and measured suction pressure near zero, which told me right away the compressor was not pumping refrigerant through the system at all. I confirmed the R-134a charge was depleted due to the compressor's internal failure rather than an external leak. I checked the compressor windings with a multimeter and found open resistance between the run and common terminals, which confirmed the LG linear compressor had failed internally. This is a well-documented failure pattern in Kenmore refrigerators built on the LG platform. These linear compressors use a piston-driven mechanism without a connecting rod, which reduces noise and energy draw during normal operation but makes them vulnerable to catastrophic internal failure, typically between years 4 and 7. The unit itself was otherwise in excellent mechanical condition, which made the repair worth completing.
🔧 The Repair
- ✓Step 1: Disconnected power and pulled the refrigerator away from the wall to access the compressor compartment at the rear base
- ✓Step 2: Attached manifold gauges and confirmed zero suction pressure, verifying the sealed system was not circulating refrigerant
- ✓Step 3: Tested compressor windings with a multimeter, confirmed open circuit between run and common terminals, diagnosed internal compressor failure
- ✓Step 4: Recovered residual R-134a refrigerant from the system using a certified recovery machine per EPA Section 608 requirements
- ✓Step 5: Cut the process tube, unsoldered the suction and discharge lines, and removed the failed LG linear compressor from the sealed system
- ✓Step 6: Installed the replacement LG linear compressor, brazed all refrigerant line connections using nitrogen-purged silver solder technique to prevent oxidation inside the copper lines
- ✓Step 7: Pressure-tested the sealed system with dry nitrogen at 150 psi for 30 minutes, confirmed zero pressure drop, then pulled a deep vacuum below 300 microns
- ✓Step 8: Charged the system with a fresh 160g R-134a refrigerant load, restored power, monitored operation for 2 hours, confirmed freezer at 0 degrees F and fresh food compartment at 37 degrees F
✓ Result
After a 2 to 2.5 hour repair, the Kenmore 795.74025.411 was cooling again. The freezer reached 0 degrees F and the fresh food section stabilized at 37 degrees F within two hours of startup. The customer was pleased to keep a refrigerator she liked rather than replace it. Total repair cost was $789. I gave her a 90-day labor warranty on the compressor replacement work. She mentioned she would recommend this service to her friends.
💡 Technician Notes
Kenmore refrigerators in the 795 series are built on the LG platform and use the same LG linear compressor found in LG-branded units. This is important because LG does not extend its compressor warranty to Kenmore-branded models, even though the internal components are identical. If you own a Kenmore in this series and it's between 4 and 8 years old, the compressor is the first thing to suspect when cooling stops completely. Do not let a technician replace the control board first without checking the sealed system. Gauge readings take 10 minutes and tell you immediately whether the compressor is the problem. Also, when this compressor fails, the sealed system is usually still clean and leak-free. That means the repair is worth doing if the rest of the refrigerator is in good condition. Budget between $700 and $850 for this repair in the Houston area including refrigerant recharge.
Frequently Asked Questions
Why did my Kenmore refrigerator stop cooling after only 5 years?
Kenmore refrigerators in the 795 series use an LG-manufactured linear compressor. These compressors are quiet and energy-efficient but have a known failure rate between years 4 and 7. When the compressor fails internally, the refrigerator loses all cooling. The age you're describing is unfortunately typical for this specific failure. The rest of the unit is usually fine, so replacement is not always necessary.
How much does it cost to replace a compressor in a Kenmore 795 series refrigerator in Houston?
In the Houston area, compressor replacement on a Kenmore 795 series unit typically runs between $700 and $850 total, including parts, labor, and refrigerant recharge. The job takes 2 to 3 hours on-site. This repair makes financial sense if the refrigerator is otherwise in good condition and is 10 years old or younger.
What happens if I ignore a Kenmore refrigerator that stopped cooling completely?
If the compressor has failed, the refrigerator will not recover on its own. Food in both the fresh food and freezer sections will spoil within 24 hours depending on ambient temperature. Running the unit without a working compressor does not cause additional damage, but every day without repair risks food loss and increases the urgency once you do call a technician.
Is it worth repairing a Kenmore 795.74025.411 or should I just replace it?
At 5 to 6 years old, this refrigerator has significant useful life remaining. A new comparable unit costs $1,200 to $1,800 in Houston retail stores. A compressor replacement at $789 is a reasonable investment. The sealed system, cabinet, ice maker, and controls on this model are well-built. If only the compressor has failed, repair is the smarter financial decision in most cases.
Does the LG warranty cover compressor failure in a Kenmore refrigerator?
No. LG does not extend its compressor warranty to Kenmore-branded refrigerators, even though the 795 series uses an identical LG linear compressor. Kenmore's manufacturer warranty may apply if the unit is still within its original coverage period, but that window is typically 1 year for parts and labor. After that, the repair cost falls entirely to the owner.
