Electrical Fault Finding — Gauteng
Systematic electrical diagnosis of refrigeration control circuits, contactors, overloads, sensors and wiring across commercial systems.
Diagnostic Process
The structured sequence we follow on every electrical faults call — to isolate the root cause, not just the symptom.
- 01Verify supply voltage, phase balance and circuit protection
- 02Test contactor contacts, coil and chatter under load
- 03Check compressor overload, motor protection and start components
- 04Trace control circuit: thermostat, pressure switches, defrost timers
- 05Inspect wiring, terminals and connections for heat damage
- 06Test sensors and controllers against measured temperature

Frequently Asked Questions
My refrigeration keeps tripping the breaker — what causes that?
Common causes are a shorted compressor, failed contactor, moisture in the circuit, or an overload. We isolate the fault rather than repeatedly resetting the breaker.
Do you work on three-phase refrigeration electrics?
Yes. We diagnose three-phase compressors, phase protection and contactors across commercial cold rooms and cold storage.
Can you repair the controller and sensors?
Yes. We test and replace thermostats, electronic controllers and temperature sensors.
