Excerpt: The LG MA62LCEG is a reliable hermetic reciprocating compressor designed for low back pressure (LBP) applications using R134a refrigerant. Rated at approximately 1/5 HP, it delivers 174W (596 BTU/h) cooling capacity with 127W input power and a solid COP of 1.38.
LG MA62LCEG Compressor – Technical Breakdown and Real-World Performance
As a field technician who’s worked hands-on with countless LG units over the years, I can tell you the MA62LCEG stands out in the MA series for its balance of efficiency, quiet operation, and durability in everyday refrigeration setups. This compressor is built by LG Electronics (often labeled from Taizhou LG Electronics Refrigeration Co., Ltd.), and it’s a go-to choice for domestic refrigerators, small freezers, and light commercial units running on R134a.
Key nameplate details include:
- Voltage: 220-240V, 50Hz, single-phase
- Refrigerant: R134a
- Motor type: RSIR (Resistance Start Induction Run) with PTC relay
- Thermal protection: Internal thermostat protected
- Application: LBP (Low Back Pressure), suited for freezing and cooling from around -30°C to -10°C evaporating temperature
Performance Specifications Table
| Parameter | Value | Notes |
|---|---|---|
| Cooling Capacity | 174 W (596 BTU/h) | At standard LBP test conditions |
| Input Power | 127 W | Efficient draw for its class |
| COP (Coefficient of Performance) | 1.38 | Good energy efficiency ratio |
| Horsepower Rating | ~1/5 HP | Common rating in this displacement |
| Net Weight | 9.1 kg | Compact and easy to handle |
| Motor Type | RSIR, PTC starter | Simple, reliable start mechanism |
| Packing (pcs/pallet) | 80 | Bulk shipping efficiency |
These figures come straight from LG’s MA series lineup comparisons. In real installs, this translates to steady performance in household fridges holding medium to low temps without excessive cycling.
Comparison with Similar LG MA Series Models
To give you context as an engineer or technician, here’s how the MA62LCEG stacks up against close siblings:
| Model | Capacity (W) | Input (W) | COP | HP Approx | Best For |
|---|---|---|---|---|---|
| MA53LAEG | 142 | 106 | 1.34 | ~1/6+ | Smaller fridges |
| MA57LBEG | 160 | 119 | 1.35 | ~1/5 | Mid-range domestic |
| MA62LCEG | 174 | 127 | 1.38 | 1/5 | Larger cabinets, light commercial |
| MA69LCEG | 200 | 148 | 1.35 | ~1/4 | Higher load applications |
The MA62LCEG edges out the MA57 with better COP and higher capacity, making it a smart upgrade when you need a bit more pull without jumping to larger frames. Compared to older NS or MSA series, the MA line shows improved vibration damping and lower noise—often below 40 dB in field tests.
Benefits and Practical Advantages
- Energy Efficiency — That 1.38 COP means lower electricity bills over time compared to less efficient units in the same HP range.
- Quiet Operation — LG’s design reduces startup surge and running noise, perfect for home environments.
- Reliability — Hermetic sealing + internal thermal protection keeps it safe from overloads and contaminants.
- Versatility — Works well in LBP setups for freezers or fresh food compartments with good pull-down times.
Installation Tips and Pro Notices from Field Experience
Always mount it on rubber grommets to cut vibration transfer. Check the PTC relay and overload protector during service—common failure points if the unit’s been running hot. Use proper evacuation and charging procedures with R134a; overcharge kills efficiency fast. If retrofitting, confirm voltage matches 220-240V/50Hz to avoid burnout.
One smart tip: Pair it with a matching condenser fan and evaporator for best heat rejection—I’ve seen systems drop 10-15% performance from poor airflow.
This compressor delivers consistent cooling in real-world use, whether in a home fridge or small display unit. Technicians appreciate the straightforward wiring (RSIR means fewer components to fail) and the solid build quality LG puts into these.

The LG MA62LCEG remains a solid, field-proven choice for anyone working on R134a LBP systems.
