Yes, refrigerators do have fuses.
Fuses are often used in refrigerators to protect appliances from short circuits. They are usually found inside the refrigerator, near the compressor.
If your refrigerator fuse was broken, would you know how to fix it?
In this article, we’ll show you how to find the fuse in a refrigerator and replace it if needed.
What are fuses?
If you’re having trouble with your refrigerator, it’s probably because one of its fuses has blown. You can fix it by replacing the blown fuse with a new one.
Fuses look like tiny little cylinder rods that have a transparent glass center with both ends of the cylinder being covered by metal caps.
There are electrical components that protect appliances from electrical surges. They’re used to protect electrical circuits from being overloaded or damaged.
When something exceeds the limits of what the fuse can handle, the fuse will blow, protecting the device from further damage.
When there’s a problem with the electricity, the fuse will blow and interrupt the current flow.
What do they do?
A thermal fuse is a cut that uses a one-way fuse. It’s called “one-way” because it only allows current to flow in one direction.
Once current flows through the thermal fuse, it gets locked into place, and no more current can pass through it.
A refrigerator thermal fuse is quite different from a circuit breaker, as it does not reset itself when the temperature drops.
Fuses are designed to protect appliances from being turned off by accident or from overheating, but they can also save your life!
That’s right: if your refrigerator has an electrical fault and starts to overheat, this little guy will shut off the power before there’s any chance of fire or electrocution.
The parts to a thermal fuse are a composition of a sliding contact (can also be called moving contact), a spring, and a fusible body of an electrically non-conductive thermal pellet.
You can only activate the refrigerator thermal fuse after the current flows to the fuse. When the current flows through the fuse, it melts it and breaks contact with the sliding contact.
This means that if your refrigerator has a problem with over-heating, this little guy will shut off the power before there’s any chance of fire or electrocution.
Where can you find the fuse in a refrigerator?
Refrigerators do have fuses and they are often in one of two places.
Most fridge fuses are located inside the fridge behind the paneling that makes the interior walls of the refrigerator or on the rear bottom of the fridge, near the compressor.
The main fuse of your fridge is the thermal fuse that is used to help the refrigerator to regulate the temperature of the interior of the fridge.
It also helps to keep the lights on inside the fridge and helps to keep the fridge going.
You can find out more about where your fuse is located by looking at your owner’s manual or doing a quick search about your model to figure out where the fuse in your particular model fridge is located.
How do you know when your refrigerator fuse has blown out?
The first, and a most obvious, sign that your refrigerator fuse has blown is that nothing in the fridge is working.
A thermal fuse works to keep the motherboard of your fridge running. When this fuse is not working, the fridge is not going to be working.
It is not going to make any humming from the compressor moving, it is not going to be cold inside, the fridge light is not going to be working, and the whole fridge is going to not work at all.
If the fuse of your fridge is out, the entire fridge is going to be out of service, even if it is plugged into a stable power source.
How do you fix a blown fuse on your fridge?
There are some tips that you can follow to help get your fuse replaced.
- First, make sure your fridge’s power source is working and that there is nothing wrong.
- Then, make sure you get the plan for your fridge and figure out where your fuse is, you should do this before you try to open anything up.
- Unplug the fridge and empty it out if you can and make sure it is in an easy-to-access area.
- You then need to access the control board. You can then look at the fuses that are located inside the control board.
- If you notice that the main line fuse or the thermal fuse is damaged, you then need to replace it.
- There are a few different things that you can do to see what might have caused that fuse to blow. Your fridge does have a computer in it so you need to make sure it is plugged into a surge protector to help protect that fuse.
- You can use a jumper wire to see if there is any issue with the control board or if it was just a freak accident that caused your fuse to blow.
- The jumper wire helps to monitor the current to make sure that there is not an issue with the board but rather with the power source. If there is not any damage to the board, you can then solder in a new fuse to get your fridge back up and running.
What are some common causes of blown fuses on fridges?
It overloaded the circuit
When appliances are too heavily loaded on one circuit, the fuse’s internal safety system will break any internal wire that has become overloaded. This can cause the fuse to blow up and stop working.
To calculate the actual load on the fuse, technicians have to measure the power drawn by all devices and appliances connected to the fridge-freezer circuit.
If the total power drawn by these individual devices exceeds the maximum load that the circuit can handle, relocate some of the devices to another circuit to free up some load.
The refrigerator is made up of a number of electronic components all of which need power in order to work properly
If they’re overloaded by too many devices being plugged into the same outlet, then it’s likely that something will give out before long!
Keep in mind that this doesn’t just apply to your fridge. It also applies to washing machines, dishwashers, and other large appliances as well!
There was a sudden power surge
A sudden power surge can cause problems with your Frigidaire refrigerator. If there was a power surge, it might have blown the fuse on your fridge.
Some older refrigerators don’t have electrical fuses, so if there is no power supply to the fridge, the mainboard may get damaged.
So if you think you’ve experienced a power surge that might have caused issues with your refrigerator, it’s best to get an authorized technician to attend to the problem as soon as possible.
Blown fuses are a common cause of current spikes that can damage refrigerator components such as motors, compressors, and electronic controls.
You can install a surge protector at the plug to protect Frigidaire refrigerators from power surges.
You have a faulty fuse
If you notice that your fridge is not chilling as quickly as usual, or if it’s running continuously but not making any food or drinks cold, it might be time to check the fuse.
If the fuse is blown, you’ll need to replace it in order to get your fridge back up and running.
It’s always best to consult a professional when dealing with delicate electronic equipment like refrigerators but if you’re feeling brave (or desperate), there are some simple steps you can take to try troubleshooting the issue yourself.
The refrigerator was faulty
It’s possible that the refrigerator was faulty because of an electrical outage.
Make sure the power cord is not damaged before checking if the refrigerator is faulty.
Check that the electrical outlet is working properly and that there isn’t any interference from other appliances in the house before concluding that the refrigerator might be faulty.
How can you prevent blown fuses on your fridge?
The best way to prevent a fuse from blowing in your fridge is to make sure you have your fridge plugged into a protected outlet.
You can either get a GFI outlet that will trip the power source at the outlet if there is a surge, or you can get a surge protector to plug your fridge into.
This helps to cut the power to the fridge before it gets to the fuse and before it gets to the control board. This will help keep the fuses intact and will slow down the amount of work that you have to do.
How long do refrigerator fuses last?
Refrigerator fuses should last the life of the machine if there is nothing serious that happens to them.
If there are no power surges, no issues with damage to the fridge, and more, the fuse should last for years.
The typical life of a fridge is 10 to 15 years, so that is typically the life expectancy of a fuse.
What’s the difference between a refrigerator thermal fuse versus a normal fuse?
The main difference between a fridge fuse and a typical fuse is the way that they are made.
Fridge fuses are often larger than a typical fuse and they are meant to help the fridge maintain the same temperature overall.
These fuses are going to be tube fuses, this means that they are glass tubes with the fust inside and metal caps on either end.
Where can you get help for fridge problems?
If you are having trouble with your fridge you do have a few options.
You can first and foremost contact the customer service for the company that makes your fridge.
You may be able to arrange for a service technician to come and see what they can do.
If you have a warranty, this may be paid for. If that is not an option, you may be able to call a local appliance repair company to come and see if they can figure out what the issue with your fridge really is.
