Air-cooled chiller compressor start-up issue repair

Air-Cooled Chiller Compressor Start-Up Issue Repair – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we specialize in diagnosing and repairing start-up issues in air-cooled chiller compressors, ensuring reliable and efficient operation from the moment your system powers on. Compressor start-up problems can result from electrical faults, control issues, mechanical resistance, or refrigerant imbalances—all of which can lead to frequent tripping, delayed cooling, or complete failure to start.

Common Compressor Start-Up Issues We Repair

• Compressor fails to start or starts intermittently

• Frequent tripping of circuit breakers or overload protectors

• Unusual humming, clicking, or buzzing during start-up

• High inrush current or voltage imbalance

• Delayed start-up or system lockout due to control faults

Causes of Start-Up Failures

• Faulty start relays, capacitors, or contactors

• Motor winding problems or insulation breakdown

• Low voltage or phase imbalance

• Seized or locked compressor components

• Refrigerant flooding or oil migration issues

• Malfunctioning sensors, timers, or control boards

Our Compressor Start-Up Repair Process

Diagnostic Testing
We begin with a comprehensive inspection of the compressor and its associated systems using:

• Multimeters and clamp meters for voltage and amperage checks

• Megohmmeters for motor winding resistance testing

• Thermal imaging to detect hot spots or electrical overload

• Control system interface diagnostics

Electrical Component Inspection
We test and replace faulty:

• Start/run capacitors

• Relays and contactors

• Overload protection devices

• Wiring and terminal connections

Mechanical Inspection
If the issue is internal, we check for:

• Bearing or piston seizure

• Shaft misalignment

• Oil pressure problems

• Internal blockages or refrigerant floodback

Control System Check
We inspect and troubleshoot the control board, pressure switches, timers, and sensors to ensure proper start-up sequencing and logic.

Testing and Commissioning
After repairs, we run a complete start-up cycle to verify:

• Smooth, reliable compressor activation

• Stable current draw and voltage balance

• Correct refrigerant pressures

• Proper oil return and load response
