Capacitors are an essential component of any electrical appliance. These capacitors help a product to run correctly. But these products become damaged in the course of time and become bad capacitors. These bad capacitors can cause a lot of problems.
You may ask if a bad capacitor tripped a breaker or not. Let us help you find the answer you are looking for and provide some insights into the matter.
Can a bad capacitor trip a breaker?
A bad capacitor can trip a breaker. A bad capacitor can cause an issue in the flow of power thus, the machine may not receive the necessary amount of power to operate. It causes a breaker to trip. Though this is not a big issue, it can become a massive problem in the long run if kept unsolved.

A bad capacitor is a massive problem for any electrical component. This causes a lot of problems in operating a machine properly. This causes an unstable flow of electricity to an appliance’s electrical components, which causes a breaker to trip.
Various appliances and devices face this problem often. For example, it is common to see that a pool pump capacitor may go bad. Due to continuous operation, it may cause the capacitor to go bad and cause a breaker to trip. Thus, stopping the pump now and then without any warning.
Another appliance that faces this issue often is an air conditioner. The ac capacitor on the device may get worse due to lack of power. Thus, the device will not receive enough power to operate. Therefore it can cause the breaker to trip.
There are various types of capacitors in an appliance or device that can get worse and cause a breaker to trip. You may want to know which capacitors can get bad. Here are some capacitors that we think can get bad often and cause a breaker to trip:
Bad start capacitor:
Start capacitor can get bad which can cause a breaker to trip. Start capacitors help a device or appliance to get the necessary amount of power to start itself.
If there is a bad start capacitor, it will prevent the device from receiving the required amount of power to start by tripping the breaker.
Bad run capacitor:
Run capacitors are essential for running any device or appliance properly. If there is a bad run capacitor, this will prevent the flow of normal power and cause the breaker to trip.
How does a bad capacitor trip a breaker?
A capacitor is vital for the supply of power to the components of an appliance or device. This helps to provide the device with the necessary amount of power required to start or run. Thus, the appliance or device will run smoothly without tripping the breaker.
It ensures the stable flow of electricity.
If there is a bad capacitor, then there will be problems with the device or appliance. The device will not receive the necessary amount of power when required by the device or machine to operate. Thus, the device or appliance will trip the breaker.
It can cause an unstable flow of electricity as well. Unstable electricity means the frequency of the electricity will not be normal. Therefore, the breaker will trip to keep the device safe from getting harmed or damaged.
What does a bad capacitor do?
There are various problems that a bad capacitor may cause due. All of these problems cause a lot of issues to users
It will create a lot of sounds:
A bad capacitor will create a lot of noise in the appliance. This is caused due to the high electricity flow in the bad capacitor and preventing this flow to the other components of the device.
The device or appliance will turn off on its own:
Due to the lack of power for a bad capacitor, the device or appliance will mourn from the proper flow of the required amount of electricity.
Thus, when the appliance will require a certain amount of electricity and does not receive it, it will shut down immediately due to tripping of a breaker
The device or appliance will not turn on immediately:
Appliances require 2 – 3 times more power to turn on and this is provided by starting capacitors. If there is a bad starting capacitor, it will hinder the flow of electricity required to turn the device on. Thus, you will have to try multiple times to turn it on.
The device or appliance will not even turn on:
A bad capacitor may even prevent the device from turning on by entirely blocking the flow of electricity.
What are the symptoms of a faulty capacitor?
A faulty capacitor causes a lot of problems to a device or appliance. Therefore, these problems can be taken as symptoms of a bad capacitor. If you want to know some common symptoms of a faulty capacitor, here are some common symptoms of this issue:
High electricity bills:
The user may find that the appliance is consuming more power than before. Therefore, the electricity bills will increase and cost you more money in your electricity bills.
Weird sound from the device or appliance:
You may hear a weird buzz sound from the appliance. A bad capacitor basically causes this. This sound may be loud or mild. It depends on the damage of the capacitor.
Cannot turn off turn on immediately or may not turn on:
The appliance will not turn on immediately. You may have to try multiple times to turn it on. The appliance may not even turn on if there is a severely bad capacitor.
Cannot work as expected:
You may not receive the expected results by running the appliance sometimes. Such as, if you have an air conditioner and find that the air conditioner is not cooling your room correctly, then it might be a symptom of a bad capacitor.
How to test a bad capacitor?
There are many ways to test if your appliance or device has a bad capacitor or not. Here are some simple ways so that you can test if your device or appliance has a bad capacitor or not:
Disconnect the device or appliance from the power source:
The first thing to do before working inside an appliance or device is to disconnect it from the power source. Unplug it from the power source by removing it from the power socket to ensure that it is not receiving any power.
Remove the access panel of the device or appliance:
All devices or appliances have a panel over them which is placed with screws. Unscrew them using a screwdriver and remove the panel to get access to the parts of the appliance.
Check the written capacitor values on the capacitor:
There will be various values written on the capacitors. Find the value which indicates the voltage of the capacitor.
Get a multimeter and connect the leads with the terminals of the capacitors:
Collect a multimeter and start it in voltage mode to check the voltage of the capacitor. Take the leads of the multimeter and connect them with the capacitor terminals according to positive and negative.
Read the multimeter reading:
Check the multimeter value. If the value is lower than the voltage written on the capacitor or if the reading is zero, then the capacitor is bad.
How to replace a bad capacitor?
There are many ways that you can use to change a bad capacitor. Here are some simple steps that we think are ideal for you to replace a bad capacitor:
Disconnect the appliance from the power source:
Turn off the appliance. Afterward, disconnect it from the power source by unplugging it.
Remove the access panel of the appliance:
Find the screws of the access panel. Use the appropriate screwdriver and remove the screws from the access panel. Remove the access panel afterward.
Identify the bad capacitor and find the replacement part:
Use a multimeter and identify the bad capacitors. Find the replacement capacitor of the same values from your nearest electrical shop.
Desolder the bad capacitor and replace it with a new one:
Use a soldering iron and remove the bad capacitor. Replace it with the new capacitor that you bought. Place it correctly on the board and solder it properly so that it is in place on the board.
Put back the access panel and test by powering the device:
Put the access panel back on the appliance. Connect the device to the power source and check if the appliance is running correctly or not.
A bad capacitor can trip a breaker of any device or appliance. It causes a lack of power or an unstable flow of electricity, forcing a breaker to trip. By tripping, it keeps the device safe from any harm or damage. This issue will worsen if left unchecked and may even make it irreparable.
