Onsite generator repairs, servicing & maintenance across Gauteng
Randburg Generator Specialists
ProService Generator Repairs provides onsite generator repairs, servicing, maintenance, diagnostics and fault finding across Randburg. The work covers residential generators, commercial sets and standby installations at the premises where they are installed.

Technicians travel to homes, complexes, estates, offices, shops, workshops and other business premises across Randburg. Ferndale and Cresta carry more office and retail sets. Randpark Ridge, Boskruin and Bromhof are mostly house and complex standby machines. Honeydew adds workshop diesels. Johannesburg North is a separate booking and does not absorb these streets.
A set that will not start is usually a weak battery, a starter fault, fuel that is not arriving, a blocked filter, or a controller alarm. A set that cranks and will not fire is fuel, air in the lines, or a shutdown. A set that runs with no voltage, or with voltage that wanders, is an AVR, alternator, breaker or wiring job, measured after the engine is steady.
ATS and AMF faults are read on the control panel: an automatic start that never calls, a transfer that does not move, or a generator that will not accept the load. Overheating is coolant, the radiator, leaks, the fan or belt, and how hard the set is loaded. Those are not the same repair as a flat battery.
Scheduled servicing covers oil, filters, coolant and the charging circuit while the supply is still on. Preventative maintenance is how a standby set is checked before the next outage, rather than after it has already failed. Each suburb below has its own page.

These are the generator services booked on Randburg callouts.
Starting, fuel, electrical, cooling, controller and output faults diagnosed at the premises.
Oil, filters, coolant, an inspection and a starting-system check on a planned visit.
Scheduled servicing so a standby set is tested before the next outage.
Breakdown support when a set has failed. Availability is confirmed on the call.
Diagnosis, servicing and repair for diesel generators across Randburg.
Smaller petrol sets where a property still uses one.
Installation where a new set or changeover is part of the job.
No output, low voltage or unstable voltage measured once the engine is running.
Alarms, auto-start failure and ATS or AMF transfer faults read on the panel.
Filters, contaminated fuel, air, and delivery faults after the simple restrictions are clear.
Rewinding when tests show the windings, not the AVR.
A controlled load test when a start on its own does not prove the set.
Battery, starter, fuel and shutdown checks before parts are swapped.
An engine that turns and will not fire, traced through fuel and filters.
Engine running, with no usable voltage at the site.
Temperature shutdowns traced through coolant, the radiator, airflow and load.
These notes describe how a Randburg fault is split on site. They are not a home repair procedure.
A click or no crank can be the battery, the starter, fuel supply, a blocked filter, a shutdown alarm or a controller fault.
An engine that turns and will not fire points at fuel delivery, a blocked filter, air in the lines, an injector-related fault or a shutdown.
If the engine is running and the site stays dark, the AVR, alternator, excitation, breaker and wiring are tested.
Hunting voltage can sit in the AVR, the alternator, the wiring, the load or the controller.
Frequency follows engine speed, the governor, the control settings and whether the engine can hold that speed under load.
Filters, contaminated fuel, air, a lift pump, the fuel pump or injectors can stop delivery on a set that otherwise cranks.
Alarms, a failed auto-start, a transfer that does not move, a shutdown, or a generator that will not accept load are read on the panel.
Temperature shutdowns are checked against coolant, the radiator, leaks, the fan or belts, the load and the service condition.
A Randburg generator that will not start can be a failed battery, a starter fault, fuel that is not arriving, a blocked filter, a controller alarm, a shutdown sensor, wiring, or a missed service. A click with no crank is not the same repair as an engine that turns and will not fire.
Diagnosis names the cause before parts are recommended. Replacing the battery, the filters and the controller together hides which fault was real. Call, WhatsApp or request a quote and say whether the set clicks, cranks, or never tries to start.
No output voltage, with the engine already running, may involve the AVR, the alternator, excitation, a breaker or the wiring. Low or unstable voltage can be the regulator, the load, the wiring or the controller. Low frequency is engine speed, the governor, the controller or the load.
Readings are taken on site. There is no safe home adjustment for excitation or governor settings, and none is described here.
Controller alarms, an automatic start that never calls, an ATS or AMF that does not transfer, a latched shutdown, or a set that runs and will not take the load are panel faults until tests show otherwise. Communication faults on the controller are read there before the unit is condemned.
Diesel servicing covers oil, filters, coolant, the battery and fuel delivery. Contaminated diesel, injectors, the lift pump and the fuel pump are separate from a routine service and only follow once filters and air are clear. The controls are checked on the same visit when the set is automatic.
