Electrical Fault — Emergency Diagnosis & Repair

Recognising these signs early can prevent total product loss:

• Plant won't start, or starts intermittently
• Breaker or RCD tripping when the plant runs
• Burning smell, scorched contactor, or hot terminals
• Erratic operation — fans or compressor cut out randomly

Take these steps now, before our technician arrives:

• If you smell burning or see scorching, isolate the plant at the main switch immediately.
• Do not keep resetting a tripping breaker — it indicates a live fault.
• Note which breaker trips and when — on start-up or after running.
• Call REYDS for a qualified refrigeration electrical fault diagnosis.

Our technicians check each of these in turn to pinpoint the fault:

• Failed contactor — Pitted or welded contacts cause poor starting, overheating, or single-phasing that damages the compressor.
• Wiring degradation — Heat and vibration loosen or burn terminals, causing intermittent opens or shorts.
• Motor insulation failure — A compressor or fan motor winding breaks down to earth, tripping an RCD.
• Overload or phase fault — A failed overload or phase-loss protector either won't trip or trips falsely.

REYDS inspects the control panel, tests contactors and overloads, meggers the compressor and fan motors for earth faults, repairs or replaces damaged wiring and components, and verifies correct starting sequence and amperage before returning the plant to service.

An annual control-panel inspection — tightening terminals, checking contactors, and meggering motors — prevents most electrical faults and extends compressor life.
