If your standby generator is not operating as it should, something may be wrong. Just as we would check our cars when we sense a problem, it is best to inspect your generator when you spot a sign of malfunction. Small problems easily grow into bigger and more expensive cases if you do not take care of them on time.

Signs That Your Generator Needs Attention

Here are signs to know when your unit needs attention:

1. You Can See a Visible Damage

This may be obvious, but some people usually ignore the sign, thinking it would go away. What they do not know is that neglecting visible damage on the generator will not make the problem vanish overnight. The first thing to check for is any wire that is frayed, loose, or worn.

Another common problem is a ripped pull cord. In this case, you can either replace the cord by yourself or call a professional to assist you. You can watch this video to learn how to repair a broken cord.

Visible damage may also occur on the exterior of an automatic generator due to hurricane damage or mischievous outdoor pests. You can inspect your unit for chewed wires, dents, corrosion, or any other visible imperfection every 6 months, or very often.

2. You Have Not Used the Unit in the Last 6 Months

If you have a portable generator, running it frequently helps to keep the battery of the electric starter charged and fresh. This also applies to automatic units. It ensures that everything is intact when you really need to use the unit.

Businesses and homeowners usually discover that their units are faulty after leaving them idle for a long time. Sometimes, it takes quick maintenance to resolve the problem. Other times, there may be extensive and costly damage, especially if sludge accumulates in the lines or there is corrosion due to the inactivity.

3. It Gives Off a Strange Noise or Smell

If your unit emits a strange smell, then something is wrong. There may be a gas leak, which is a sign of a fire hazard. It is also a concern for the health safety of the homeowner or business owner.

In the same vein, bizarre sounds such as rattling, squeaking, and humming are unusual noises that a generator may make. This may be due to some factors like low fuel and an overworked unit. It may be difficult to diagnose except you seek help from a professional.

4. There is Inconsistent Power

In this case, the unit is supplying power, but it is not consistent. It turns on and turns off at will. This problem is due to internal damage. Also, flickering lights show that you do not have the correct wattage generator to meet your electric needs.

5. There is Delay During Start-Up

If your unit does not start immediately or hesitates when you fire it up, there may be internal problems. It could mean that the unit is using old or bad fuel, the fuel filter is due for replacement, or there is sludge in the lines or tank.

The unit may eventually start after the third try, but such issues should not be ignored. The next time you try to start it, it may not turn on at all.

6. The Unit is Running, But It Is Not Supplying Power

This is quite tricky because the problem may be with your unit or your breakers. Here, you should get a trusted electrician to test the electric panel. They will determine if the problem is from there or from your generator.

Prevention is Better Than Cure

This advice may not help an already failing generator, but it is still correct. Carrying out routine maintenance helps to identify potential issues before they are severe. In addition to that, scheduling regular maintenance helps to extend the useful life of your unit, thereby, improving its efficiency and saving you some money over time.

Find a Licensed Generator Repair Service and Maintenance Professional

If you are a handy person, you may attempt servicing your unit by yourself. But just like other electrical repairs, this is dangerous. You may get hurt in the process, void the warranty, and cause more problems that will require a licensed generator repair service to resolve.

This also applies to hiring an uncertified and unlicensed technician or general handyman. You are at risk of more damage to the generator due to improper repairs, which may affect both of you immediately, and just you, later, when the repair fails.
