Warning signs of circuit board failure become immediately apparent when burning odours or scorch marks appear around your electrical equipment. A persistent burning odour emanating from your switchboard indicates a severe electrical fault, typically accompanied by heat generation and smouldering insulation. This situation presents an immediate fire hazard that requires professional intervention and board replacement.
Visual indicators like scorch marks or burns around the switchboard, power points, or wiring are evidence of previous electrical fires and reveal significant underlying system issues. When electrical wiring shows signs of melting or charring, it demonstrates exposure to excessive heat, usually resulting from the board's inability to properly regulate and distribute electrical loads.
Similarly, discoloured or damaged power points and switches exhibiting arcing or burning signs point to the board's failure to safely manage power demands throughout the property. The presence of any burning smells, coupled with visible damage around electrical components, definitively signals that your switchboard has critical deficiencies. These conditions demand immediate assessment and intervention by a licensed electrician to address potentially catastrophic fire and safety risks.

Throughout your home, flickering or dimming lights serve as telltale indicators of an overwhelmed switchboard struggling to maintain consistent power distribution. When lights consistently flicker or dim, particularly when major appliances are running, it signals that your switchboard is operating beyond its intended capacity, creating an unstable power supply throughout your home's circuits.
This issue is particularly common in older homes equipped with outdated 60-150 amp electrical service systems. As modern households demand more power for various devices and appliances, these ageing panels often prove insufficient in managing the increased electrical load. The result is visible through intermittent lighting fluctuations, which occur when the switchboard cannot effectively distribute power to all circuits simultaneously.
When you notice persistent flickering or dim lights, it's crucial to address the situation promptly. These symptoms indicate your switchboard is overloaded and requires professional evaluation. An experienced electrician can assess whether your switchboard needs an upgrade to a higher amperage service to meet your home's current electrical demands. Ignoring these warning signs could lead to more severe electrical issues and potentially compromise your home's safety.
