Control Panel Repairs.
From Relays to Controllers.
The control panel is the brain of your generator. When it fails, the engine may not start, the load may not transfer, or persistent fault codes prevent operation. We diagnose and repair control systems across all generator types throughout Gauteng.
What We Fix
Common Control Panel Faults
Failed start relays
The generator cranks but does not start, or fails to crank at all despite battery power. Start relay or fuel solenoid failure are common culprits.
Controller fault codes
AMF and ATS digital controllers displaying persistent fault codes — sensor alarms, communication errors, over-speed, under-speed, or shutdown faults.
Automatic transfer failure
Generator starts but does not transfer the load, or fails to retransfer back to mains. ATS contactor or controller configuration faults.
Sensor & sender faults
Oil pressure, coolant temperature, and fuel level senders sending incorrect readings, causing nuisance shutdowns or masking real faults.
Wiring & connection damage
Corroded terminals, rodent damage, vibration-induced chafing, and failed circuit breakers inside the control panel causing intermittent faults.
Controller programming & upgrades
Incorrect settings, outdated firmware, or older mechanical panels requiring upgrade to modern digital controllers for reliable automatic operation.
The Service
Generator Control Panel Repair Across Gauteng
The control panel manages every aspect of your generator's operation — starting sequences, engine parameter monitoring, output control, and automatic load transfer in standby applications. When panel components fail, the consequences range from a generator that will not start at all, to one that runs but shuts down unexpectedly under load, or fails to transfer power to your building when mains is lost.
Control panel problems range from straightforward component failures to complex controller malfunctions. A failed start relay, a faulty fuel solenoid, or a defective oil pressure sender are discrete, repairable faults. A malfunctioning AMF controller with persistent fault codes, a misconfigured ATS that fails to transfer, or corrupted firmware on a digital controller require a different approach. Our technicians are experienced with both.
We work with all major controller brands — Deep Sea Electronics, ComAp, Woodward, Deepsea, SmartGen, and others. We can read and interpret fault logs, adjust operational settings, update firmware, replace failed controller modules, and reconfigure systems following a change in installation requirements. If your generator uses a proprietary panel from the original manufacturer, we can diagnose it at the component level rather than replacing the whole assembly.

Control panel diagnosis — fault codes read and interpreted on-site
For older generators operating with basic mechanical controls, we offer upgrades to modern digital AMF controller systems. These upgrades deliver significant improvements in reliability, monitoring depth, and automatic operation — including remote monitoring capabilities for facilities that need off-site visibility of generator status. We assess your specific installation and recommend an upgrade path that adds genuine value without unnecessary complexity.
Every control panel repair is completed with a full function test. We verify the auto-start sequence, load transfer operation, shutdown protection activation, and fault alarm behaviour before leaving site. The generator must perform correctly through a complete operational cycle — not just power on — before the job is closed.
Our Repair Process
Systematic fault diagnosis
We read fault logs, test sensors and relays individually, and trace wiring methodically. We find the root cause, not just the symptom.
Targeted component repair
Relays, solenoids, breakers, and sensors replaced as required. We do not swap out the whole panel when a single component has failed.
Controller programming & configuration
We read, adjust, and restore settings on Deep Sea, ComAp, Woodward, and other major controller brands — including firmware updates where needed.
Full function test before handover
Auto-start sequence, load transfer, shutdown protection, and fault alarm testing confirmed before leaving site.

Controller Expertise
All Major Controller Brands Supported
Modern standby generators use sophisticated digital controllers that monitor dozens of engine and electrical parameters simultaneously. These systems provide detailed fault logging, configurable alarm thresholds, and remote monitoring capabilities — but require proper setup and maintenance to function correctly.
We are experienced across all major brands in use across Gauteng. Deep Sea Electronics controllers — from basic DSE 6020 units to advanced DSE 8610 MKII modules — are among the most common, and we handle fault diagnosis, configuration, and replacement across the full DSE range. We carry the same capability for ComAp, Woodward, and SmartGen systems.
