A standby generator is only valuable when it works, and like any mechanical and electrical system, generators require professional attention when problems arise. Whether your generator fails to start during an outage, runs but does not carry the load, or produces warning codes you cannot interpret, Anthony’s Home Services provides reliable generator repair service for homeowners throughout Somerset, NJ and Central Jersey.
Generator problems often show up at the worst possible times, such as during an active storm or after months of the unit sitting in standby mode. Our technicians are trained to diagnose issues quickly, communicate the problem clearly, and complete repairs with the parts and expertise needed to get your system back online. We service all major residential generator brands and work on units of all ages.
Common Generator Repair Issues We Diagnose and Fix
Standby generators share a common set of failure points that our technicians encounter regularly. Understanding what can go wrong helps homeowners recognize when to call for service before a minor issue becomes a complete system failure. At Anthony’s Home Services, we approach every repair with a full diagnostic evaluation, not just a quick fix of the visible symptom, to make sure the underlying cause is resolved.
Generator Problems We Repair
- Failure to Start: Battery problems, low oil shutoff triggers, and control board faults are among the most common reasons a generator does not start when utility power fails.
- Transfer Switch Issues: A faulty transfer switch may prevent your home from switching to generator power even when the generator itself is running correctly, leaving you without backup power.
- Oil and Coolant Leaks: Leaks from the engine block, hoses, or gaskets can trigger automatic shutdown and require immediate attention to prevent long-term engine damage.
- Fuel System Problems: Carburetor buildup, fuel solenoid failures, and blocked fuel lines are common issues in generators that are not exercised regularly or are fueled by propane or gasoline.
Keeping Your Generator Ready with Regular Maintenance
Most generator repairs are preventable with routine maintenance. Annual tune-ups, oil and filter changes, battery inspections, and transfer switch testing keep your system in top condition so it performs reliably the moment you need it. Anthony’s Home Services offers generator maintenance services for Somerset homeowners who want to stay ahead of problems rather than respond to them during an outage.
Signs Your Generator Needs Service
- Warning Lights or Fault Codes: Modern standby generators display diagnostic codes when they detect a problem. Our technicians can read and interpret these codes and address the underlying fault directly.
- Unusual Noises During Operation: Knocking, rattling, or irregular exhaust sounds during a generator’s weekly self-test or actual operation often indicate mechanical issues that should not be ignored.
- Reduced Output or Voltage Fluctuations: If your generator starts but cannot support normal electrical loads, or if lights flicker and appliances struggle during an outage, a generator service call is warranted.
