Why does my generator keep revving up?

Surging caused by fuel problems usually happens for one of three reasons: incorrect fuel, low fuel levels, or poor fuel quality. Most generators have specific fuel requirements and using any type of fuel outside of those parameters can cause operational issues, including surges.

What is generator surging?

Surging refers to a generator (or other electrical component, machine, or device) displaying clear fluctuations in behavior at intervals. A surging generator often will leave lights burning much brighter, then much dimmer rapidly, causing a sort of flicker back and forth.

How do I know if my gas generator is bad?

If the color is off, that means the gasoline has oxidized and is forming gums, varnishes and deposits in the fuel. If you use that fuel in your generator, you’re likely to leave harmful deposits in the combustion areas of the generator motor.

Why is my generator not running smoothly?

The carburetor might be clogged. A clogged carburetor is most often due to leaving fuel in the generator for a long period of time. This sticky fuel can clog up the carburetor and cause the engine to stall or run roughly. If the carburetor is clogged, try cleaning it with carburetor cleaner.

What causes generator noise?

A big source of noise from most generators is the vibrations caused by the generator running that then transfer into the ground. Hard surfaces will cause these vibrations to be extremely noticeable.

Can a generator cause a power surge?

Issues with your generator could cause the system to surge, leading to power fluctuations or leaving you without power when you need it. A surging generator is an indication that there is something wrong with your equipment. Common issues which cause these surges include: Old Age.

What makes a generator sputter?

Sputters and Stalls / Clogged Filters Clogged air filters are a common problem with portable power generators. If you typically operate the generator in dusty environments such as barns or construction sites, you need to regularly clean or change your air filters.

What happens if you add too much oil to your generator?

With too much oil in your engine, its fluid level in the oil pan will be so high that it can be splashed by some of the moving parts in the engine block, specifically the crankshaft lobes and connecting rod “big ends.” That, in turn, can whip the oil into a frothy consistency, like a well-emulsified salad dressing.

What is the common problem of generator?

Batteries: Battery failure is the most common failure when it comes to generators. Always make sure the batteries, chargers, and all cables and connections leading to and from are in good condition. Failure to Start: If a generator fails to start, one cause could be the controls not being set to auto.

What RPM should my generator run?

Old gensets used to run at 300 RPM, some at 750 RPM. Newer units desired to be cheaper and lighter run at 1500 RPM. With a 4-pole generator head they generate 50Hz. For 60Hz you need 1800 RPM.
