Can a Generator Damage a Refrigerator — Proper Guide!

It is impossible to think of living without a refrigerator at home these modern days. This makes the fridge one of the main components in your house.


Since a refrigerator cannot work without electricity and there might be sudden power outages, this rising problem remains with electricity.

That is when a generator comes as your savior!

A generator can not only just power your refrigerator but also many other appliances. It includes a microwave oven, ceiling fan, heater, desktop computer, and many more.

Generators are a reliable source of temporary electricity, but the question arises, “Is it a reliable operation?”

Let’s explore together with this in-depth technical analysis.

Is it Safe to Run a Refrigerator on a Generator?

A generator is one of the safe and reliable sources of electrical supplies. But this can vary in different situations.

If your generator can provide enough watts for your refrigerator to run smoothly, then there will be no problem. But if there is some power shortage, this could be a problem for your refrigerator. This could be problematic for your refrigerator since this power shortage could damage the parts of your refrigerator. 

If you could be a little cautious about the situation, you can remove the damage your generator could inflict on your refrigerator.

Buy a generator that suits your refrigerator. Generally, between 1000-2000 watts generator is perfect for a fridge. But to be fully sure about your refrigerator’s power requirements, check the manual

Nowadays, refrigerator manufacturing companies produce refrigerators of different sizes. These refrigerators could vary between 1000, 2000, 2500 watts to start.

Do I Need a Stabilizer while Using a Generator for my Refrigerator?

A voltage fluctuation is quite common in power lines. This could result in parts failure in your device. Since we are talking about refrigerators, almost every part is important. But this problem could be solved with a carefully selected stabilizer that can solve this problem.

A stabilizer helps to stop any unnecessary voltage from passing into your electronic devices. 

A stabilizer can read the voltage fluctuations before sending it to your refrigerator. Then, it stabilizes the change and sends a constant reading to keep the fridge running when it senses the fluctuation.

For example, suppose your voltage is low. In that case, your stabilizer senses it, and it quickly balances the reading before feeding it to your refrigerator. The opposite happens when the voltage is too high for your refrigerator, and your stabilizer senses it and lowers the voltage to the optimal level before letting it reach your refrigerator. 

A stabilizer will constantly check on the voltage without fail and balance the voltage fluctuations. This allows your device to run smoothly without any parts failure or sudden shutdown.

Two Best Generators For Refrigerators

For your refrigerator to run without any power shortage, it is essential to get yourself a generator. But more importantly, to get a generator with the correct size. 

A refrigerator to run at its full potential requires between 100 to 800 amps per hour. So for most refrigerators, 2000 is the starting watts required to turn on your refrigerator without any problem. 

Below are the two best generators that you can buy right away!

Recommend Generator Starting Watts Generator Size
Generac 1200 Watts Portable Inverter Generator1200 WattsSmall
Champion Power Equipment 2500 Watts Dual Fuel Portable Inverter2500 WattsMedium

These are the top two selling generators on the market. They are super reliable and guaranteed to save your money and refrigerator from any type of harm. 

According to experts, you need to run your generator for one hour to keep your refrigerator running for four hours. But, of course, this could vary for the different sizes of refrigerators you have. 

FAQs: Related Question

Q1. Will the portable generator damage my refrigerator?

There are some chances that a portable generator can damage your refrigerator. This works because a portable generator doesn’t have a steady power supply like inverter generators, and most household appliances, especially a refrigerator, have sensitive components inside it.

These components can detect if there are any fluctuations in electricity and can be permanently damaged.

Try not to use too many devices at the same time. This could trigger power fluctuations in your generator, which could lead to the sudden shutdown of your refrigerator.

Pay close attention to the starting watts of your refrigerator. A starting watt is the amount of watts needed to start your refrigerator.

For most refrigerators, this value can range between 800-1200 watts. These values can be even less for a mini-fridge ranging between 600 and 1000 watts. Typically a portable inverter generator of 2000 watts can run a refrigerator without any problem. 

Q2. Can a 2000 watt generator run a refrigerator?

Yes, a 2000-watt generator can run a refrigerator. A 2000-watt generator is considered as the best generator for your refrigerator. This is mainly because of the starting mechanism of a refrigerator.

Typically almost all refrigerators start between 800 and 1000 watts. For your understanding, a 2000 watts generator demonstrates that the generator can work up to the maximum limit of 2000 watts. So no matter the circumstances, you cannot exceed that limit if you don’t want your generator to stop working.

Q3. Can an inverter generator run a refrigerator?

Certainly! An inverter generator is known for being efficient and lower emissions which is good for you and your environment. An inverter generator can run all your devices with the required power supply and still not run at its peak performance until necessary. 

A 2000 watts inverter generator can efficiently run your refrigerator without any problems. It can do this and still keep a steady flow of power supply. This helps to expand the lifetime of your refrigerator.

However, power surges and spikes are most common in a generator. So it is necessary to check if the generator can ensure the safety features provided by a generator. 

Q4. How often should I run my generator to keep my refrigerator cold?

Ideally, if you run your generator for 1 hour, this can keep your refrigerator cold for 4 hours. This is applicable when you have a large fridge. However, if you own a small fridge, then 1 hour of running your generator will keep your refrigerator cold for 2-3 hours.

In Fact, it makes sense to run your generator not so often. In a power shutdown, electricity could be gone for a long time. At this time, you need to power your refrigerator.

If you have a larger generator like a 6000 watts generator, running it full time shouldn’t be a problem. But if you have a small generator, consider saving up as much energy and fuel as possible before running out of fuel. 

Final Thoughts

If you use a generator properly, then no device will be harmed. However, before buying a generator, you need to ensure that it has sufficient power to run your refrigerator. 

A refrigerator is the most important device with all other electronic devices in a house. A refrigerator needs to be powered all the time to keep the valuables inside fresh and damage-free. That’s why it is important to use a generator to power your refrigerator during power outbreaks.
