Gas Generator Brands We Service
Gas Generator Repairs & Servicing
We diagnose the set you have installed. LPG, natural gas and petrol/LPG dual fuel each have their own fuel path and their own faults, so tell us the model and the fuel when you book.
Generator Repairs
We fix starting, electrical, control and output faults on every fuel type.
Generator Servicing
Oil, filters, spark plugs and a controlled start for gas standby sets.
Generator Maintenance
Planned checks that keep an automatic standby set ready between outages.
Generator Controllers
Modules, alarm codes and programming on automatic gas sets.
ATS Repairs
We fix transfer faults when the set runs but the house stays dark.
Generator Installation
Placement and commissioning when a new standby set goes in.
Generator Callouts
What to send us so we arrive with the right parts.
Control Panel Repairs
Relays, wiring and ATS interface faults inside the panel.
Common Gas & Dual-Fuel Generator Problems We Diagnose
Generator will not start
We test the battery, starter, ignition and controller, check for a latched shutdown and note any sign of a gas-supply problem.
Generator starts then stops
We check the sensors, the controller, the ignition and the fuel supply, and read the alarm that recorded why the set stopped.
Does not start automatically
We test the controller, the ATS or AMF signals, the starting battery and the wiring, and clear any shutdown that is holding the set off.
No power
Once the engine is running, we test the AVR, alternator, excitation, breaker and wiring to find where the output stops.
Low or unstable voltage
We separate AVR and alternator faults from engine speed, load and control problems, because each one needs a different repair.
Controller alarms
We record warnings, shutdowns, maintenance alarms, failed starts and auto-mode faults exactly as the screen shows them.
Battery and charging
A standby set needs a battery that can still crank after weeks of sitting. We test the battery and the charger together.
Overheating
We check airflow around the set, the cooling system and the load, and look at how recently the set was serviced.
Petrol & LPG Dual-Fuel Generator Repairs
Some portable and inverter generators can operate on petrol or on LPG, depending on the model. A dual-fuel fault is often one-sided: the set will not start on LPG, it starts on petrol but not on LPG, or it runs on LPG and will not run on petrol.
We diagnose fuel-selection faults, petrol carburettor problems, starting faults, electrical output, AVR faults and engine-speed or frequency problems on the set. We repair dual-fuel generators as the manufacturer built them. We do not convert petrol generators to LPG, because an improvised gas connection is a fire and explosion risk.
Natural Gas Standby Generator Repairs & Servicing
We work on residential and commercial natural-gas standby sets: automatic-start systems, control panels, ATS and AMF behaviour, batteries, engine servicing, generator output and scheduled maintenance.
A registered gas practitioner installs and certifies the gas piping. We take over at the generator, where we diagnose, repair and service the set itself.
LPG Generator Repairs & Servicing
On an LPG generator we repair starting problems, ignition and control faults, batteries and electrical output, and we carry out servicing and preventative maintenance. If we find a fuel-delivery fault, we show you where it is so your gas practitioner can correct it.
Leave the regulator, the gas pressure and the safety devices alone. If you smell gas, do not try to start the generator; call your gas supplier or gas practitioner first.
Gas Generator Safety
We keep gas work and generator work separate for your safety. We diagnose and repair the starting, control and output side of the set. A registered gas practitioner handles the supply, pipework, regulator and certification, and we never bypass a gas safety device to get a set running.
Other Gas Generator Systems We Can Assess
We also repair other gas-powered generators. Send the make, the model and the fault, and we check parts before we visit. For help with sizing, read our generator sizes guide, and for the full range of makes we work on, see generator makes and models.

Frequently Asked Questions
What types of gas generators do you repair?
We repair and service LPG generators, natural-gas standby generators and petrol/LPG dual-fuel generators across Gauteng. We service and repair Generac, Kohler, Cummins, Red Rhino and Steco generators.
Do you repair LPG generators?
Yes. We repair and service LPG generators, from starting, ignition and controls to output and routine servicing. A registered gas practitioner installs and certifies the gas supply to the set.
Do you service natural-gas generators?
Yes. We service and repair natural-gas standby generators, including automatic start, the controller, the battery, the engine and the electrical output. Pipework and gas certification stay with a registered gas practitioner.
Do you repair petrol and LPG dual-fuel generators?
Yes, on sets the manufacturer built to run on both fuels, such as Red Rhino and Steco dual-fuel models. Tell us which fuel the fault appears on when you book.
Can you repair a gas generator that will not start?
Yes. We test the battery, starter, controller and ignition and read any shutdown alarm. If the fault sits in the gas supply, we show you what we found so your gas practitioner can fix it.
Can you diagnose automatic-start problems?
Yes. We check auto mode, the starting battery and the alarm log, and we confirm whether the start command reaches the engine when the mains fails.
Do you repair generator controller faults?
Yes. We record the warning, shutdown or maintenance alarm exactly as the display shows it, then test the circuit it points to.
How much does a gas generator service cost?
Our cost guide puts a basic service at R900 to R1,800. Your written quote confirms the price for your set before we start any work.
Do you service gas standby generators across Gauteng?
Yes. We work across Gauteng, including Johannesburg, Pretoria, Sandton, Centurion and Midrand. We are open 24/7 and arrive within 1 hour when a standby set breaks down.
