LG Compressor LRA 74 Frequency 60 Hz, Voltage 208-230V
ر.س750.00 Inclusive of VAT
The LG Compressor LRA 74 is a genuine LG rotary compressor built for split air conditioning systems running on R22 refrigerant, rated at 208-230V / 60Hz, and fitted with built-in thermal protection that shields the internal windings from overheating during operation. It’s manufactured in Thailand under LG’s certified production lines, and is primarily used as a replacement part for failed compressors in medium-to-large capacity AC units.
The LRA code in the product name stands for Locked Rotor Amps, a technical rating that indicates the maximum current the compressor draws at startup. Within the same product family, a higher LRA number generally corresponds to a larger overall cooling capacity, and based on comparable models within LG’s rotary QP series, the LRA 74 compressor typically falls in a cooling capacity range close to 24,000 BTU (approximately 2 tons). That said, always confirm the exact model number or match it against your old compressor before ordering, since LG doesn’t publish a BTU rating directly on this model’s label.
Key Features
- Built-in thermal protection: shields the windings from damage during overheating or excess electrical load
- Genuine LG manufacturing from Thailand: built under strict, globally certified quality standards
- High-efficiency rotary design: lower power draw compared to older reciprocating compressors
- Low vibration and noise: quieter operation for residential and commercial spaces
- Compatible with 208-230V supply: falls within Saudi Arabia’s standard electrical range (approximately 220-240V)
- Fixed 60Hz frequency: suited to AC systems originally designed for this frequency

Benefits of Using This Product
Choosing a genuine LG Compressor LRA 74 over imitation or reconditioned parts gives you:
- More stable performance: built-in thermal protection reduces the risk of sudden failures caused by overheating
- Lower electricity consumption: rotary compressor efficiency reduces electrical load compared to an old, worn compressor
- Longer life for the rest of the system: a properly matched, healthy compressor reduces stress on the capacitor, expansion valve, and coil
- Fewer maintenance callouts: genuine LG quality reduces recurring failures
- An economical alternative to a full unit replacement: replacing just the compressor is far cheaper than replacing the entire AC when only the compressor has failed

Important technical note: A 208-230V rating is a globally standard voltage range used in AC compressor manufacturing, and it’s compatible with Saudi Arabia’s electrical grid (220-240V). Even so, always confirm the LRA rating and refrigerant type against your old compressor, a different LRA number within the same family indicates a different cooling capacity and current draw.
Compatible Models
The LG Compressor LRA 74 is generally compatible with AC units using:
- Rotary compressors from LG’s QP series running on R22 refrigerant at 208-230V within the same capacity range
- Split AC units with cooling capacity close to 2 tons (based on comparable LRA models)
- Light commercial systems using the same voltage and frequency specs (208-230V, 60Hz)
⚠️ Don’t rely on the LRA number alone to determine compatibility, always compare refrigerant type (R22), voltage, and connection port sizes with the old compressor or your unit’s service manual before ordering.
Installation & Usage Guide
Important disclaimer: Compressor installation requires specialized HVAC refrigeration skills and should only be performed by a qualified AC technician. The steps below are for general reference only and are not a substitute for professional installation, the manufacturer itself notes on the product page to proceed carefully and follow the included instructions closely.
- Fully disconnect electrical power to the AC unit before starting any work
- Recover R22 refrigerant from the system using certified recovery equipment, never vent refrigerant into the atmosphere, for environmental and legal reasons
- Remove the failed compressor by disconnecting electrical wiring first, then carefully de-soldering the copper connections
- Flush the refrigerant lines to remove old oil residue and contaminants before installing the new compressor
- Install the new compressor and braze the copper connections securely, avoiding air or moisture entry into the circuit
- Perform a vacuum test to confirm there are no leaks before charging refrigerant
- Charge R22 refrigerant with the correct quantity per the unit’s original specifications
- Run a test cycle, monitoring electrical current and operating pressure, and confirm the thermal protection is functioning normally
Maintenance Tips
- Clean air filters regularly: clogged filters increase compressor load and raise the risk of the thermal protection tripping frequently
- Check R22 refrigerant levels periodically: persistent low levels may indicate a leak that should be repaired before it damages the compressor
- Ensure proper ventilation around the outdoor unit: dust buildup restricts heat dissipation and raises the compressor’s operating temperature
- Monitor for unusual operating noise: any knocking or vibration can be an early sign of a mechanical issue
- Schedule seasonal maintenance: inspect the full system before the start of Saudi Arabia’s summer to avoid repeated thermal-protection trips from excess load

Frequently Asked Questions
Q1. What does the LRA code mean in an LG compressor’s name?
LRA stands for Locked Rotor Amps, the maximum current the compressor draws at the moment it starts up. It’s used as a technical indicator of cooling capacity tier within the same product family.
Q2. Does the LG Compressor LRA 74 work with Saudi Arabia’s electrical grid?
Yes, the 208-230V rating is compatible with the Kingdom’s standard electrical range (approximately 220-240V), but it’s recommended to confirm your unit’s original specifications before installation.
Q3. What’s the cooling capacity of the LRA 74 compressor?
Based on comparable models within the same LG rotary family, the cooling capacity typically falls around 24,000 BTU (roughly 2 tons), but confirming via your old compressor or contacting our technical team is recommended.
Q4. Does this compressor only work with R22 refrigerant?
Yes, this model is built for R22 refrigerant and isn’t recommended for systems running other gases like R410A or R32 without technical consultation.
Q5. What’s the benefit of built-in thermal protection on this compressor?
Thermal protection shields the internal windings from damage during overheating or excess electrical load, an especially important feature in Saudi Arabia’s extreme summer heat.
