Generator Issues and How to Fix Them!

Generator problems are something that you, we and everyone around us face over time. But there’s nothing to worry about. Every problem has a solution and so do these generator problems. Continue reading and see what problems need what solutions.

Generator Issues and How to Fix Them!

Here are some of the generator issues.

  • Starting failures
  • Fuel-Related Complications
  • Overheating
  • Electrical Malfunctions
  • Oil Leaks
  • Insufficient Oil Levels

Let’s discuss how these are problems and how you can manage them.

Starting failures

One of the most common generator problems is difficulty in starting. This could be due to a variety of factors such as a dead battery, fuel issues, or a faulty starter motor.

Solution: To address this problem, start by checking the battery and ensuring it is charged. If the battery is fine, examine the fuel supply and replace any stale fuel. Additionally, inspect the spark plugs and clean or replace them if necessary. If the starter motor is the culprit, it may need repair or replacement.

Fuel-Related Complications

Generators often face issues related to fuel, such as clogged fuel filters, carburettor problems, or contaminated fuel. Regular maintenance is crucial to prevent these problems.

Solution: Clean or replace fuel filters periodically and ensure that the fuel is clean and of the recommended type. Cleaning the carburettor can also help resolve fuel-related issues.

Overheating

Continuous operation and high ambient temperatures can result in generator overheating. Insufficient ventilation or blockages in the cooling system can exacerbate this problem.

Overheating

Solution: To solve overheating issues, ensure that the generator is placed in a well-ventilated area. Clean the cooling system regularly, including the radiator and air filters, to remove any dust or debris that could impede airflow.

Electrical Malfunctions

Faulty wiring, damaged circuit breakers, or short circuits can lead to electrical malfunctions in generators.

Solution: If you experience electrical problems, inspect the wiring for any loose connections or damage. Replace any frayed wires and ensure that all connections are secure. If a circuit breaker trips, identify the cause and address it before resetting the breaker.

Oil Leaks

Oil leaks can occur due to loose fittings, damaged seals, or worn-out gaskets and these are one of the most occurring generator problems.

Solution: Regularly inspect the generator for any signs of oil leakage and address them promptly. Tighten loose fittings, replace damaged seals, and repair or replace faulty gaskets.

Insufficient Oil Levels

Insufficient oil levels in your generator can prevent it from starting. Moreover, if the oil levels become too low, it can lead to permanent damage to the engine because it won’t have enough lubrication. To avoid engine failure, it’s important to maintain the oil at the right levels.

Insufficient Oil Levels

Solution: The solution is to keep a check on the oil levels. Checking the oil levels is not difficult. Just locate the oil dipstick, similar to a dipstick in a regular car. If the oil levels are below the full line, add more oil. Remember, it’s crucial to use the same type of oil that was previously used for safe and effective operation.

Also, check the consistency and colour of the oil. If it appears dark and sludge-like, it means the oil has deteriorated. In this case, you should have your generator completely flushed and replace the old oil with fresh oil.

  • NOTE: Remember, safety should always be a priority when dealing with generator problems. If you are unsure or uncomfortable with performing troubleshooting or repairs, it is recommended to consult a professional generator technician. Regular maintenance and proactive troubleshooting can help prevent these common issues and ensure that your generator remains reliable and functional during power outages.

Common Generator Problems – FAQs

What causes a generator to trip?
A generator can trip due to reasons such as overloading, short circuits, fuel supply issues, overheating, or low oil pressure. When you draw more amps than the circuit can handle, circuit breakers (and fuses) trip.
How to fix a generator that runs but has no power?
If your generator is running but not producing any power, there are a few steps you can take to address the issue. 1. Before beginning, make sure that the circuit breakers on both the generator and the electrical panel are not tripped. If any of them are tripped, reset them and then see if the power is restored. 2. The next step is to examine the connections between the generator and the electrical system or appliances. Connectors that are loose or damaged can interrupt power flow, so make sure they are tightened or replaced if they are damaged. 3. The voltage regulator on the generator should also be checked and ensured to be in good working order. It is recommended to consult a professional generator technician if none of these steps resolves the problem.
Why is my new generator leaking oil?
If your new generator is leaking oil, there could be a few potential reasons. It might be due to loose fittings or damaged seals, which can occur during shipping or assembly. Another possibility is that the oil drain plug or filter was not properly tightened. Additionally, there may be a defect in the gaskets or seals.
What causes overheating in a diesel engine?
Overheating in a diesel engine can be caused by factors such as low coolant levels or coolant leaks, a malfunctioning thermostat that restricts coolant flow, or clogged radiators that restrict proper heat dissipation. Other potential causes include issues with the cooling system components like the water pump, radiator fan, or exhaust restrictions.
What causes a generator to stop working?
Generally, generators that don’t produce power are victim of a failed AVR or an alternator which has lost residual magnetism. In such a case, you should replace the AVR if the voltage is between 50-70V on each phase.

 

Wrapping Up!

In a nutshell, it is crucial to understand and address common generator problems in order to sustain a reliable power supply during critical times and we’ve tried our best to make you aware of those problems and their solutions.

Remember, when in doubt or uncomfortable about repairs, it is always best to consult a professional.
