October 16, 2025

When a storm knocks out the grid, a whole-house generator is meant to keep your home running smoothly. But when that system stops working just as you need it most, frustration quickly follows. 

It may be tempting to inspect the issue yourself, but the safest choice is to contact a licensed electrician who can identify the cause and restore the system properly. Generator issues often point to a deeper electrical concern that requires professional expertise. For homeowners in Covington, working with qualified technicians to install whole-house generator systems and maintain them properly prevents costly breakdowns and restores dependable power when it matters most.

Common Causes of Generator Failure

A number of issues can lead to a generator shutting down or failing to start during a power outage. The most frequent include fuel supply interruptions, battery or starter motor failure, and clogged filters. Some units fail to start because of outdated transfer switches or corroded wiring connections. Others may shut off abruptly if sensors detect overheating or low oil pressure.

Generators that sit idle for long periods without inspection or testing are more likely to encounter these problems. A professional maintenance plan helps avoid those risks by ensuring every part of the system, from the fuel line to the control board, is inspected before the next storm hits.

Why Professional Installation Matters

Proper setup makes the difference between a generator that activates instantly and one that struggles to start. When MAD Energy NW installs a whole-house generator, the work begins with a full electrical assessment. This includes reviewing your home’s existing load, main panel condition, and power demands for appliances, heating, and lighting.

Each installation is wired directly to an automatic transfer switch, which detects when utility power fails and transfers the load to the generator within seconds. Our licensed electricians ensure every connection meets Washington electrical codes and manufacturer requirements. This level of precision protects the home’s electrical system and guarantees that the generator can deliver stable power safely under any condition.

The Role of Routine Maintenance

Generators operate most effectively when serviced at regular intervals. Annual or semi-annual inspections confirm that the engine, wiring, and fuel systems are performing correctly. Maintenance tasks often include oil and filter changes, battery testing, and system calibration.

Neglecting these steps increases the likelihood of starting issues and component damage during long outages. Professional upkeep not only prevents failures but also extends the life of the system. MAD Energy NW’s team can provide ongoing service and performance checks to keep your backup power ready whenever it’s needed.

Recognizing Signs of a Failing System

Before an outage even occurs, homeowners can look for early signs that indicate a generator may not operate correctly. Unusual noises during test cycles, delayed startup, or repeated system faults on the display panel are all indicators that something is not functioning as it should. A faint fuel odor or visible leaks also signal mechanical or line issues that require immediate attention.

It is critical not to attempt to repair or reset these components yourself. Modern generators integrate complex electrical and engine systems that trained professionals must handle to avoid safety hazards and warranty violations.

When a Generator Stops During an Outage

If your generator fails while running, turn off nonessential appliances to reduce strain on the system. Avoid touching the unit until the power source has stabilized or a technician arrives. Our electricians can inspect the generator’s automatic transfer switch, voltage output, and control wiring to identify the cause and restore reliable operation.

In many cases, a professional inspection uncovers issues that are easily preventable, such as expired fuel or loose wiring. Once power is restored, we test the full system to confirm it transitions smoothly back to grid power and is ready for the next use.

Why Covington Homeowners Should Plan Ahead

Covington’s location within the Puget Sound region means that outages caused by wind and rain are not uncommon. Preparing before storm season gives homeowners confidence that their backup system is fully functional. Scheduling a pre-season generator evaluation ensures the battery, fuel supply, and automatic transfer switch are working properly.

This preparation is particularly important for households that rely on powered heating systems, medical devices, or sump pumps. A dependable generator setup maintains safety and comfort when conditions outside become unpredictable.
