Power Outage Panic? Here’s When to Call for Generator Service and Repair

A power outage, especially during extreme weather or unexpected situations, can trigger a wave of panic. 

But before you resign yourself to a night of discomfort, consider the power of a reliable backup generator. The Washington Post reports that in 2002, only 0.63% of U.S. homes had backup generators. This figure has since risen to 5.77%, indicating significant growth in the adoption of home backup power solutions.

However, regular generator service and repair are crucial for making sure that your machine remains in optimal working condition. So, how do you know when a minor power outage is simply a waiting game, and when it’s time to call for generator service and repair?

Strange Noises and Unusual Odors

Your generator shouldn’t sound like a distressed airplane engine. Grinding, clanging, or any abnormal noises could indicate internal problems like worn bearings or loose components. 

Generators that are not maintained regularly also risk leaking carbon monoxide. It cannot be easily detected because it is a colorless and odorless gas while being extremely toxic. 

The Consumer Product Safety Commission reports around 85 annual deaths in the U.S. due to carbon monoxide poisoning from defective generators.

Similarly, a pungent burning smell might signify overheating due to a clogged cooling system or an electrical issue caused by faulty wiring. In both cases, shut down the generator immediately and contact a service professional to prevent further damage and ensure the safety of your home.

Power Fluctuations and Inconsistent Output

Flickering lights or appliances that struggle to maintain power are signs your generator isn’t delivering a steady current. This inconsistency can damage electronics like TVs and computers by causing power surges. 

Water Well Journal notes that power surges or power spikes are a critical part of power supply quality. The origins and impact of these occurrences can vary substantially. Generally, a surge is defined as a rise of at least 10% over the base current and voltage, lasting just a few microseconds.

It can also reduce the overall effectiveness of your backup system, leaving essential appliances like refrigerators and freezers vulnerable during extended outages. A qualified technician can diagnose the cause of the fluctuations, such as a faulty voltage regulator or a failing alternator.

Battery Issues and Starting Problems

Colorado Standby notes that if your generator struggles to turn over or fails to start entirely, the battery might be the culprit. A dead or weak battery won’t deliver the necessary spark to ignite the engine. 

While a jumpstart might get you going temporarily, a service technician can test the battery’s health and recommend a replacement if needed. According to Facilities Management Advisor, a technician generally suggests replacing a generator battery once every 2-5 years.

Additionally, they can check the starter motor and ensure all connections are clean and secure to prevent future starting problems.

Decreased Runtime and Fuel Inefficiency

Has your once-reliable generator seen a significant drop in runtime on a single tank of fuel? This could be due to clogged filters, inefficient fuel consumption caused by a dirty carburetor, or engine wear and tear that reduces overall efficiency. 

A service visit can address these issues by replacing clogged filters, cleaning the carburetor, and performing any necessary adjustments to optimize fuel usage. This can extend your generator’s runtime during an outage, saving you money on fuel costs in the long run.

Lifehacker notes that draining the fuel tank is advisable when storing a portable generator. This is because leftover fuel can degrade in extreme temperatures, which may prevent the generator from starting in an emergency. Additionally, old gasoline can clog the fuel line and engine parts.

FAQs

Can generators produce carbon monoxide?

Yes, generators can produce carbon monoxide (CO). This colorless, odorless gas results from the incomplete combustion of fuel. Operating a generator in an enclosed or poorly ventilated area increases the risk of CO buildup, which can be deadly.

What is a power surge in a generator?

A power surge in a generator is a sudden increase in voltage. This spike, also known as a transient, can exceed the normal operating voltage by 10% or more, lasting only a few microseconds. Power surges can damage sensitive electronic equipment connected to the generator.

Why is my generator draining my battery?

Your generator might be draining the battery due to a parasitic load, a faulty charging system, or an old battery. Parasitic loads are small electrical draws that continue even when the generator is off. Regularly checking and maintaining the battery and charging system can prevent unnecessary drainage.

In summary, maintaining a generator through regular service and prompt repairs is crucial for ensuring its reliability during power outages. Recognizing the signs of potential issues, such as unusual noises, power fluctuations, starting problems, and decreased efficiency, can prevent serious damage and enhance safety. 

Effective generator maintenance not only protects your appliances and home but also maximizes fuel efficiency and extends the generator’s lifespan. Proactive care, including professional inspections and timely repairs, ensures that your backup power solution remains dependable when you need it most.
