Generators play an important role in your home's power system, but they are used so infrequently that it's easy to forget they need regular maintenance and inspections.

The last thing you want to do when the electricity is out in your home is inspect your generator by flashlight to try to fix whatever issue has popped up. Your generator could power:

  • Outlets
  • Microwave
  • Air conditioner or heater
  • Lights
  • Sump pump
  • Water well pump
  • Refrigerator

Most manufacturers recommend that, along with getting regular maintenance done by your trusted electrician, whole-house generators should be tested monthly to keep them running as efficiently as possible. This informal inspection doesn't need to take long; here are some red flags you should look for:

Is it slow to start?

One of the earliest and most telling signs that your generator needs repair is a slow or delayed start. It should take less than a minute for your machine to take over during a power outage, and you should have the same timing when you test your system.

A delay in power may indicate an engine or battery problem, low oil level, clogged fuel valve or carburetor, or a bad spark plug.

Do you see any worn wires?

Frayed or overly worn wires and cables can reduce efficiency and increase fire risk. While there are always precautions to be taken when working with a generator, any time you can see past the protective outer coating and into the active electrical elements, there is an even higher risk of electrocution and fire. In general, most electrical components will be visible or easily accessible for quick inspection.

If you notice that your wires are beginning to show their age, it is best to call an electrician to take a look before touching anything yourself. These repairs are not typically too expensive or time-consuming for an expert. 

Is there a fluid leak?

Like your car, your generator needs fluid to run properly. If you notice puddles of iridescent liquid under or around your generator, chances are you have a fluid leak. You would smell gas almost immediately, so if you don't notice that distinctive odor, you probably have an oil leak. Either way, you'll want to contact a professional to fix the leak immediately.

Can you see any signs of body damage?

This isn't a trick question. Like anything else stored outside, your generator is vulnerable to things like fallen tree branches and wild animals that can do serious exterior damage, while the inside components are typically well protected. A dent or a hole in the shell is another reason to call a professional.

Has the battery gone bad?

Your generator’s battery should be replaced every 2-3 years, depending on how often it is used and how exposed it is to water and other potentially damaging forces. Signs that it's time for a replacement include visible damage or corrosion.

If your battery can be recharged, you should regularly check the charge level and ensure you have enough energy to get you and your household through a 24-hour power outage.

It's best not to try to change the battery yourself, as improper installation can cause severe damage to the whole generator.

Don't forget about regular maintenance

Aside from the inspection points listed above, you should have a certified technician perform regular cleaning and maintenance to ensure that your unit is ready to work at full power at any given moment.

Whole-house generator maintenance might include changing air and oil filters, changing the oil, replacing old spark plugs, and checking voltage levels. They might also need to clean the sediment traps and the rest of your generator system inside and out. Typically, they should be serviced every 6 months.
