Iron's Electricity: Why Do They Always Cut Out?

why do iron always cut out electricity

Irons are a common household item, but they can sometimes cause electrical problems. In some cases, an iron may cause a power cut or trip a circuit breaker. This can be caused by a variety of factors, such as a faulty appliance, a short circuit, or a leak. For example, a leaking water tank or internal steam leakage can lead to corrosion of electrical contacts, affecting the thermostat and causing the iron to overheat or shut down. Overloading a circuit by using multiple electrical devices simultaneously can also contribute to power issues. To address these problems, it is recommended to consult an electrician, perform repairs, or replace the iron. Understanding and resolving these electrical issues is essential for maintaining a safe and functional household environment.

Circuit overload

Irons can sometimes cut out electricity due to a circuit overload. Circuit overloads occur when more electrical current is drawn through a circuit than it was designed to handle. Every electrical circuit has a limit, typically marked by the size of the breaker or fuse connected to it. If too many devices or appliances are plugged into the same circuit, the circuit can become overloaded.

Circuits can vary in their capacity, and the wiring in a circuit is only as good as its weakest point. For example, a 1500-watt space heater plugged into a 15-amp circuit can cause an overload. Similarly, using one or two blow dryers or curling irons simultaneously on the same circuit can cause an overload. An oversized or normal-sized window air conditioner can also cause an overload.

There are several warning signs of a circuit overload. Frequently tripped circuit breakers are a common sign, as breakers are designed to cut off the electrical supply when they detect too much current flowing through the circuit. Dimming or flickering lights, especially when turning on large appliances, can also indicate an overloaded circuit. This is because the circuit struggles to supply sufficient power, causing a voltage drop that makes the lights appear dimmer. Warm or hot outlets or switches are another warning sign, as overloaded circuits generate excess heat. A burning smell near an outlet, appliance, or power strip is a serious warning that the circuit is overloaded.

If you suspect a circuit overload, you can try to fix it by following these general steps:

  • Check the breaker box to identify which switch turned off.
  • Unplug all devices from the affected circuit.
  • Reset the breaker by switching it back to the "on" position.
  • Start plugging things back in one by one to identify any particular appliance that may be causing the overload.
  • If the overload persists, redistribute the load by unplugging unnecessary devices or plugging high-wattage devices into separate circuits.

If the issue cannot be resolved, it may be necessary to consult a licensed electrician. They can assess the situation, identify the root cause, and suggest appropriate repairs or upgrades.

Faulty appliance

If your iron is causing electricity to cut out, it could be due to a faulty appliance. A common cause of this is a problem with the iron's cord, which can fail due to frequent movement or where it enters the cord "boot". If the cord is faulty, about 1" of the end should be cut off and a new plug installed.

Another potential issue is a build-up of fluff, lint, or water inside the iron, which can create a fault as the fluff dries. This is especially common in steam irons. It is also possible that the iron's heating element has failed, leading to a current leaking to earth and tripping the RCD.

If you suspect that your iron is faulty, it is recommended that you stop using it immediately and get it repaired or replaced. You can get a PAT inspection to check for any faults, and some fire brigades will also check small electrical items to ensure they are safe. It is important to take these precautions to avoid any potential safety hazards, such as electrical shocks or fires.

Water tank leaks

Another cause of water tank leaks is a clogged steam vent, which can be prevented by regularly cleaning the steam vents and using distilled water to avoid mineral buildup. If the iron is not heated enough, water may drip instead of being converted into steam, so allowing the iron to fully heat up before activating the steam function is crucial. It is also important to match the temperature setting to the fabric being ironed.

In some cases, the thermostat may be defective, causing the iron to leak water instead of releasing steam. To check if the thermostat is the issue, increase the setting to maximum; if the water does not turn into steam, the thermostat likely needs to be replaced. If the water tank itself is damaged or cracked, it will need to be replaced as well.

Descaling the iron using a vinegar-water solution or a store-bought descaler can help clear mineral deposits and improve steam flow, reducing leaks. It is also important to regularly clean the iron to prevent buildup and potential leaks. If the leak persists despite trying these troubleshooting methods, there may be an internal issue that requires professional attention or manufacturer inspection and repair.

Automatic power cut

Electric irons have an automatic power cut function that turns the power on and off. This is made possible by a thermostat that silently tracks the temperature and turns the power on and off with the help of other electric components. The thermostat helps to regulate the temperature within safe limits, preventing the iron from getting too hot when turned on and left unattended for a long time. This is important because if the iron continuously draws electricity from the power supply, the heating element will get hotter and hotter, leading to energy waste and potentially dangerous accidents.

The automatic power cut function can be frustrating for users who may find their irons switching on and off repeatedly during the ironing process. This frequent making and breaking of the circuit to regulate temperature leads to gradual wear and tear of the contact points. This can cause electromagnetic interference with radio reception, which can be prevented by connecting a capacitor across two contact points.

In addition to the thermostat, some steam irons include control electronics that may turn the iron off or reduce power if left stationary for a while. This is another safety feature that helps to prevent accidents.

However, irons can also cause electrical problems, such as tripping the circuit and causing a power outage. This can be due to a faulty appliance, with damage to the cable, body, or plug connections. It could also be caused by a short circuit or a leakage of steam or water, leading to corrosion of the electrical contacts and affecting the thermostat. In some cases, it may be an issue with the circuit being overloaded or the socket being faulty.

To address these issues, it is recommended to get a PAT inspection on the appliance and have it repaired or replaced if necessary. It is important not to use a faulty iron as it can pose a safety risk.

Current leakage

Another cause of current leakage in irons is a faulty appliance. This could be due to a frayed or damaged mains lead, a worn cable, or a break in one of the conductors caused by repeated twisting. A faulty appliance can also be caused by a short circuit, which can lead to tripping the Residual Current Device (RCD) protecting the socket circuit. In some cases, the problem may lie with the socket itself, rather than the iron.

To mitigate current leakage in irons, it is important to regularly clean and maintain the appliance, including the steam vents, and to use distilled water to prevent mineral deposits from blocking the vents. Additionally, allowing the iron to fully heat up before using the steam function and turning off the steam function when ironing at lower temperatures can help prevent leaks.

While current leakage is a common issue, it can also have serious consequences. It can lead to power waste, affect the performance of electronic devices, and in the case of irons, it can even cause electrical shocks or electrocuting individuals if the water tank leaks into the wiring. Therefore, it is important to address the issue promptly and seek professional help if needed.

Overall, current leakage in irons can be caused by a variety of factors, including steam leakage, faulty appliances, and socket issues. Regular maintenance and proper usage can help mitigate these issues, but it is important to prioritize safety and seek professional assistance if the problem persists or poses a risk of electrical shock.
