Is It Common For Air Conditioner Units Blink?

This is a built-in feature in almost every air conditioner unit to notify the owner that something may be wrong with the device. Companies like Toshiba would often include in their manual how to deal with a blinking light if it ever happens.

So, if you see your air conditioner at home flashing a light repeatedly, do not fret. This is the machine's way of telling you that something is wrong with it, no matter how small it may be. As such, keep the manual around in case of such emergencies.

Reasons For Blinking Air Conditioner

As stated earlier, the most common reason your Toshiba air conditioner isn't working is dirty filters. This prevents the unit from performing at its optimal best, and as such, it causes its efficiency to drop. It will flash a green light repeatedly as it shuts down to notify you when that happens.

However, there are cases where dirty filters are not the problem. One common problem that most air conditioner units run into is a fault in the wiring. This could cause the machine's circuit board to overload itself and eventually shut down to prevent further harm.

If everything checks out, though, and there is nothing irregular with the circuitry, it's time for maintenance. Air conditioner units, especially ones that are a little older, need to be checked twice a year by a technician. This is the device's way of reminding you that it too needs to be cared for like humans when we get sick.

Another factor is that the air conditioner's refrigerant levels are too low to continue working. Refrigerant is the working fluid used in air conditioners that allow them to blow cool air into a room.

Compressor failure is another common factor in air conditioners, especially those found in warm climates. This is the result of the air conditioner working too hard on a hot day, causing it to wear out the parts inside of it. If this happens, consult a technician as this needs to be dealt with immediately.

Flashing Green Light On AC Unit

If your air conditioner is flashing green light, this is a standard indicator that the machine needs to be cleaned, an electrical problem, or gas valve problems. Below, we discuss them and more.

Electrical Problems

When the air conditioner unit detects something wrong with its electrical circuits, it would shut down and immediately flash a green light to warn you. This failsafe helps protect the machine and your home from any electrical accidents.

This usually happens when there's been an overload of voltage in the machine's circuit board or the electrical wiring is experiencing some issues. Call a technician to check your machine.

Improper Installation

When installing a Toshiba air conditioner for the first time, it may take a while for you to get the hang of it. Don't be alarmed when the machine starts flashing green light. This means that something went wrong with the installation.

Go over the manual again if you feel like something went wrong. If you're unable to pinpoint the problem, don't hesitate to call a technician.

Poor Circulation

Poor circulation is one of the most common problems an air conditioner unit faces. This usually happens when the filter is dirty, causing the AC unit to struggle because the clogged filters cannot produce any clean air and won't cool as effectively.

Clogged filters will also result in a foul smell. Because the machine cannot circulate and filter air properly, dust and dirt particles will settle in the air and affect those with respiratory problems.

Additionally, clogged filters can cause problems like water leakage to occur. Because the air isn't circulating properly, causing warm air to get trapped and condensation to form. Regularly cleaning the filters should avoid this issue.

Some homeowners would also buy an air purifier or a humidifier. This helps filter any unwanted dust, dirt, and smell that could otherwise strain your air conditioner in the long run.

Refrigerant Leak

If you notice that your air conditioner light is blinking green and has difficulty keeping the room cool, it might be running low on refrigerant. Worse, it may have leaked all over the inside of your machine.

Immediately shut the air conditioner off to prevent any electrical shortages from happening. Afterward, carefully place a used rag or some paper towels over the area where the coolant is dripping and forming a puddle.

Then, call a professional. Refrigerant is a chemical that should only be handled by those who have undergone proper training.

Do not be alarmed if you see a red light flashing from your air conditioner unit. This indicates that the machine isn't able to run correctly.

Usually, the air conditioner needs to be reset, or the system needs to be started up. This happens when the circuit breaker trips due to outside interference.

Dust and dirt particles can prevent your air conditioner from working correctly, causing the system at the back to fail while the indoor unit continues running. This would result in either tripping the circuit breaker or blowing a fuse.

The best way to fix a blinking air conditioner light is to prevent it from happening in the first place. That means regularly keeping up with the machine's maintenance and keeping it clean and free from dirt.

Regularly taking the filters out every three months would also help as this is the most common issue that causes a blinking light from the air conditioner. Call in a technician for problems beyond your capability, like a refrigerant leak or a worn-down condenser unit.

Being able to fix your air conditioner is a personal achievement in itself but always remember when to seek professional help. Technicians are there to make your lives easier and prevent further damage to your machine.

How To Reset An Air Conditioner Unit?

Most Toshiba air conditioner units have a button on their remote, which you can use to restart the system of the machine. It's a simple and efficient way of resetting their product.

However, in case the remote doesn't work, or you can't find it, simply resetting it as normal would suffice. Make sure to turn the circuit breaker off the air conditioner and let it rest for a few minutes. Afterward, turn the circuit breaker back on and let the air conditioner start at the lowest setting.

Afterward, return the air conditioner to your desired temperature. Doing this also resolves most blinking light issues.
