The Service
Urgent generator breakdown and callout assistance
A generator failure during loadshedding or a critical power outage never arrives on schedule. ProService Generator Repairs provides emergency callouts across Gauteng for urgent breakdowns. A same-day appointment is offered only when a slot is open. The time is confirmed on the call. An arrival minute is not guaranteed.
Technicians carry diagnostic equipment and some common parts, including batteries, sensors, belts, fuel filters and oil. If a part is not on the van, that is said before it is ordered. A first-visit repair is not promised.
We operate across a broad range of generator types and makes — diesel standby generators for commercial, industrial, and residential properties. Whether the fault lies in the engine, alternator, fuel system, control panel, or electrical connections, our technicians have the experience to diagnose it correctly and restore operation quickly.
Before any repair begins, we provide a full upfront diagnosis. You receive a clear explanation of what failed, what caused the fault, and exactly what the repair will cost. There are no surprise invoices. If a required part is not on the vehicle, we communicate that immediately and source it as fast as possible to minimise your total downtime.
A breakdown at a shop, a workshop or a factory is booked the same way: the suburb, the fault and the next open slot. No site type is promised a faster arrival than another.

Common Fault Types
What we are usually called out for
01
Generator fails to start
Flat starter battery, faulty solenoid, flooded engine, low oil shutdown, control board fault — we diagnose and repair the root cause on-site.
02
Generator starts but trips off
Overload conditions, coolant temperature faults, low oil pressure, AVR failure, or governor problems causing shutdown under load.
03
No output voltage
AVR failure, excitation winding faults, or control panel issues resulting in a running generator that produces no usable power.
04
Fuel system failure
Blocked fuel filters, contaminated diesel, failed lift pump, or air in the fuel system preventing the engine from sustaining operation.
05
Control panel fault codes
AMF and ATS controller faults including sensor alarms, communication errors, and configuration issues preventing automatic operation.
06
Overheating & coolant faults
Blocked radiators, coolant leaks, failed thermostats, and low coolant levels causing high-temperature shutdowns under load.
What to Expect
Honest Diagnosis. No Surprises.
When our technician arrives, the first step is always a full diagnostic assessment. We do not quote before we understand the fault. This means you get an accurate repair cost based on what is actually wrong — not a guess.
Once you approve the quote, repair work begins immediately. We keep you informed throughout and confirm the generator is running correctly before leaving your site. A post-repair functional test under realistic load conditions is part of every emergency callout.
If a part is not on the vehicle, that is said before it is ordered. An arrival minute is not promised, and a temporary generator is not offered as part of the callout.

Google Review
At 9 PM during Stage 6, our primary generator tripped. Their emergency team was on-site that evening, bypassed a burnt contactor to restore power, and permanently fixed it the next day.

Common Questions
Emergency generator repairs — questions
Can I book an urgent generator callout?
Yes. Call or WhatsApp 082 057 4605 and describe the fault and the suburb. The visit is arranged from that information. A response-time promise is not published.
What should I say when the generator is down?
Whether it cranks, whether it fires, whether any voltage appears, and any alarm on the controller. A photo of the plate helps. Unknown answers can be left blank.
Should I keep resetting a shutdown alarm?
No, if the alarm is low oil pressure or high temperature. Those can be real protection events. Repeated resets can damage the engine. Stop and book a diagnosis.
Do urgent visits cover diesel and petrol sets?
Yes. Say which fuel it is. A diesel that cranks and will not fire is a different job from a petrol set with stale fuel.
Can you attend businesses and homes?
Yes. Commercial standby sets and smaller home generators are both attended across Gauteng. Access and the size are confirmed when the visit is booked.
What if the engine runs and the building is still dark?
That is often a breaker, AVR or transfer fault rather than another start attempt. Leave the set stopped if you are unsure, and describe that pattern when you call.
Still unsure what the fault is? Call or WhatsApp 082 057 4605 for onsite diagnosis.
