Before You Replace Your Compressor, Read This!
=======================
A failed air-conditioner compressor is usually the result of another problem—not the problem itself.
Before replacing a compressor, be it new or reconditioned one, it is important to identify the root cause to avoid another failure. Here are some of the most common reasons compressors fail:
🔌 Electrical Issues
• Voltage fluctuations or power surges
• Faulty capacitors, relays, or contactors
• Loose electrical connections
• Frequent short cycling
❄️ Refrigerant Problems
• Low refrigerant due to leaks
• Overcharged system
• Incorrect refrigerant
🛢️ Lubrication Failure
• Low or contaminated compressor oil
• Oil breakdown from overheating
• Incorrect oil type
💧 Liquid Floodback / Slugging
Compressors are designed to compress vapor—not liquid. Liquid refrigerant returning to the compressor can cause severe internal damage.
🌡️ High Operating Temperatures
Often caused by:
• Dirty condenser coils
• Blocked airflow
• Condenser fan failure
• High head pressure
🌬️ Poor Airflow
• Dirty air filters
• Clogged evaporator or condenser coils
• Faulty indoor or outdoor fans
⚙️ Mechanical Wear & Contamination
• Normal wear over time
• Moisture, dirt, or acid contamination inside the system
🛠️ Poor Installation or Maintenance
• Incorrect refrigerant charge
• Inadequate system evacuation
• Improper piping practices
• Failure to replace filter driers after repairs
💡 Key Takeaway:
A compressor rarely "just fails." As Boss Soong says, "Jangan salahkan compressor. Jangan jadikan compressor sebagai mangsa." Finding and correcting the root cause is essential to ensure the new compressor delivers reliable, long-term performance.
P/S: We offer a wide range of reconditioned compressors (rotary compressor, scroll compressor, reciprocating compressor, etc.) that look 99% just like new ones! WhatsApp Boss Soong at any time for more information 📲 016-227 7929
