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.
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
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
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
Ensures fast and consistent cooling on demand
Prevents equipment damage and unnecessary downtime
Reduces electrical stress and energy spikes
Extends compressor and component life
