Standby generators are often required to work in challenging environments. This can diminish the generator's capacity and lead to malfunctions. A malfunction easily hinders operations, halts production, or damages machinery. This is why it is always advisable to perform any known repairs before worn and damaged components cause breakdowns. With proper care and maintenance, Generac standby generators are designed to operate efficiently and provide reliable power for decades down the road.

Common Causes of Generator Failures

Leaks in the Coolant System

When coolant leaks and reservoir levels fall below acceptable limits, heat sensors within the generator will switch the unit off. There are numerous potential causes of coolant leaks that include leaking engine cylinder gaskets, cracked cylinder heads, and defective sleeves.

Faulty or Damaged Wiring

Over time, wiring can corrode, fray, or be cut. Damaged wiring is a critical repair that should not be postponed. Signs of deficient wiring may include low voltage warnings, malfunctioning gauges, and tripped breakers.

Fuel Failures

Fuel failures are a common cause of generator repair. Many fuel failures are the result of contamination from within the fuel tank. As algae, bacteria, and sediments get sucked into the system, they can cause diminished performance and block fuel lines.

Bad Belts

Belts can wear out with regular usage. They can also wear simply due to old age. Worn, dry, or cracked belts are easily visible and should be replaced before they have a chance to break.

Dead Batteries

Batteries should be replaced every 2-3 years to ensure maximum reliability. It is not advisable to prolong replacement beyond the 3-year mark as this may result in an unanticipated failure.

Burnt Components

Electrical components, motors, circuit boards, transfer coils, and other components can be subjected to extreme temperatures during generator operation. Exposure to high temperature can damage these components and lead to malfunctions.

The Importance of Regular Maintenance

Regular maintenance helps uncover minor problems before they cause major disruptions. It is always advisable to adhere to the recommended maintenance schedule advised by the equipment manufacturer. This schedule is a guideline and not an absolute. The older the generator becomes, the more frequently you will need to perform repairs and replace parts.

If the generator is under heavy use, positioned within a moist or dusty environment, or showing signs of defects, it is advisable to schedule a service call by a qualified technician. Prompt performance of repairs can help protect your system from critical component failure and ensure that you don't void the warranty.
