Kenmore Elite 795.74305.810: Refrigerant Leak Repair in Cypress, TX
📞 Call (346) 512-3688🔧 Performed by Alex Z.
The Problem
- •Fresh food section warming to 55–60°F while the freezer still attempted to cool
- •Refrigerator running continuously without reaching target temperatures
- •No frost buildup on the evaporator coil despite the compressor running
- •Audible hissing near the back wall of the fresh food compartment
- •Food spoiling within 24–36 hours of the compressor cycling on
🔍 Diagnosis
When I arrived at the Cypress home, the Kenmore Elite 795.74305.810 had a fresh food compartment reading 58°F and a freezer section at 28°F. The compressor was running nonstop, and I could hear it laboring harder than normal. I connected my Fieldpiece manifold gauges to the low-side service port and found suction pressure at 2 psi, well below the 24–28 psi normal operating range for an R-134a system at ambient conditions. High-side pressure read 95 psi, also low, confirming the system was severely undercharged. I used an electronic refrigerant leak detector to trace the source and found the leak concentrated at the fresh food evaporator coil, a known weak point on this 795-series Kenmore Elite platform. The aluminum evaporator coil had developed a pinhole fracture, likely accelerated by formic acid corrosion, which is common in Kenmore Elite units built on the LG chassis after years of humidity exposure typical of the Houston area. With the coil breached, the compressor had been running dry under extreme stress, which compromised the compressor internals. The dryer filter, which sits in the sealed system to remove moisture, was also saturated and no longer protecting the system. All three components required replacement to restore the sealed system to factory integrity.
🔧 The Repair
- ✓Step 1: Recovered all remaining R-134a refrigerant from the sealed system using a Fieldpiece MR45 recovery machine, collecting approximately 1.8 oz of the original 4.76 oz charge, confirming significant refrigerant loss through the leak.
- ✓Step 2: Removed the fresh food compartment rear panel and foam insulation to access the evaporator coil assembly mounted behind the liner of the Kenmore Elite 795.74305.810.
- ✓Step 3: Cut and desoldered the failed aluminum evaporator coil from the refrigerant lines, cleaned the copper tubing ends, and prepared them for the replacement coil fitment.
- ✓Step 4: Installed a compatible replacement fresh food evaporator coil, silver-soldered all joints under nitrogen flow to prevent oxidation scale inside the copper tubing.
- ✓Step 5: Replaced the failed compressor with an OEM-compatible unit rated for the 795-series platform, torqued all mounting bolts and wiring terminals to spec.
- ✓Step 6: Installed a new dryer filter inline with the liquid line, replacing the saturated original unit to protect the rebuilt sealed system from residual moisture.
- ✓Step 7: Pulled the system down to 500 microns using a two-stage vacuum pump, held the vacuum for 30 minutes to confirm zero leak-up before charging.
- ✓Step 8: Charged the system with exactly 4.76 oz of R-134a per the label specification, monitored operating pressures until stabilized at 26 psi suction and 160 psi high side. After a 2-hour runtime, fresh food compartment read 37°F and freezer read 1°F, both within factory spec.
✓ Result
The Kenmore Elite 795.74305.810 reached stable operating temperatures within two hours of the recharge. Fresh food section settled at 37°F and the freezer held at 1°F. The compressor was running quietly and cycling normally, no longer laboring continuously. The homeowner in the Cypress 77429 area was relieved because they had a full week of groceries at risk. They mentioned they had been monitoring the temperatures for two days hoping the unit would recover on its own. A 90-day warranty was provided on parts and labor for the sealed system work.
💡 Technician Notes
Kenmore Elite refrigerators built on the LG 795-series chassis have a specific vulnerability worth knowing. The aluminum evaporator coil in the fresh food section is prone to formicary corrosion, a pinhole pitting caused by trace organic compounds in the air reacting with the aluminum over time. Houston humidity accelerates this process. The earliest warning sign is a refrigerator that runs constantly but only the freezer stays cold while the fresh food section gradually warms over several days. That asymmetric cooling pattern, freezer working but fridge not, points directly to a sealed system leak rather than a fan or defrost issue. To slow the progression of this problem, keep the inside of the refrigerator clean and well-ventilated and avoid storing strong-smelling organic materials uncovered. If you notice the compressor running for more than 20 minutes without cycling off, call a technician. Waiting more than 48 hours after you notice warming food risks compressor burnout, which turns a coil repair into a full sealed system overhaul.
Frequently Asked Questions
Why is my Kenmore Elite 795 refrigerator not cooling but the freezer still works?
On the Kenmore Elite 795-series, this asymmetric cooling pattern most often points to a refrigerant leak in the fresh food evaporator coil. The freezer section shares the sealed system but its coil is typically intact, so it holds temperature longer. As refrigerant escapes through the cracked fresh food coil, the fridge side loses cooling first while the freezer appears to function for a few more days.
How much does it cost to repair a refrigerant leak on a Kenmore Elite refrigerator in Cypress TX?
A refrigerant leak repair on a Kenmore Elite that requires evaporator coil and compressor replacement typically runs between $600 and $950 in the Cypress area, depending on parts availability and labor time. If only the coil needs replacement and the compressor is still healthy, the cost is lower, usually $350 to $500. Sealed system work is labor-intensive and requires EPA 608 certification to handle R-134a refrigerant legally.
What happens if I ignore a refrigerant leak in my Kenmore Elite refrigerator?
If the leak is left unaddressed, the compressor will continue running dry without refrigerant lubrication. Within days, compressor internals overheat and seize. What starts as a coil leak becomes a full sealed system failure. You also risk total food loss. On the Kenmore Elite 795-series, I have seen units go from a repairable coil leak to a burned compressor in under 72 hours once refrigerant drops below critical levels.
Is it worth repairing a Kenmore Elite 795 refrigerator with a refrigerant leak or should I replace it?
If the unit is under 10 years old and the compressor has not burned out, repair is worth it. The Kenmore Elite 795-series is a well-built LG-chassis refrigerator and replacement cost for a comparable unit exceeds $1,800 to $2,500. A full sealed system overhaul at $700 to $950 makes financial sense. If the compressor is seized and the coil is also failed simultaneously on a unit older than 12 years, replacement becomes the more practical option.
Why did the compressor and dryer filter need to be replaced along with the evaporator coil on my Kenmore Elite?
When an evaporator coil leaks on the Kenmore Elite 795-series, the compressor runs continuously without adequate refrigerant, which strips lubrication oil from the cylinder walls and valve plates. The dryer filter becomes saturated with moisture that entered the system through the breach point. Replacing only the coil and leaving a stressed compressor and wet filter drier in place is a setup for another failure within months. All three components work as a system.
