If your projector is overheating when playing games or watching movies, then it is time to keep your projector cool.
But sometimes, these projectors shut off, or their internal parts get damaged due to overheating.
Overheating is a major problem with most projectors because either their ventilation system is choked due to dust particles or the fan stops working when there is no regular cleaning.
To keep your projector cool and prevent it from shutting off, we will discuss how to keep projector cool and extend its lifespan with simple steps to follow.
Reasons Your Projector May Be Overheating
There are numerous reasons projectors start overheating when there is no proper ventilation inside the room, and you use your projector for long sessions.
It is important to allow proper airflow inside the projector so that the hot air can pass easily.
Blocking the fans of a projector is another reason that causes overheating. Sometimes the front vents get blocked by toys, books, or even remote controls, making it harder for a fan to flow the air quickly.
Also, when there is no regular cleaning of the unit, the dust particles play a role in blocking the vents, and then the hot air will build up inside your projector, increasing its temperature.
If the projector is placed in a hot and humid location, it will cause rapid warm-up and less cooling.
Never place your projector on a carpet or any other heat absorbent surface because this will cause less ventilation and increased overheating of your projector.
If you place the projector in an open location that receives much sunlight, the unit will overheat even though how clean your projector is.
Remember the projectors are designed for specific temperatures and humidity only.
So, never place them in such conditions, which will not only makes the unit hot but also decreases its lifespan.
Dirty Air Filter
After some time, the projector’s air filter becomes dirty, making its internal part hot. You should clean the projector filter at regular intervals to ensure that dust does not block the airflow of your device.
If the filter is very dirty, then you can also use a vacuum cleaner to clean up all dust particles from inside.
You must always refer to the user manual for instructions when performing the cleaning task because different types of projectors have different ways of cleaning air filters.
How To Keep Projector Cool?
Cleaning Air Filter
Cleaning the projector’s air filter is not easy; if you have not done the cleaning for a more extended period, it’s time to clean the choked-up air filter.
Also, if you purchased a refurbished one, chances are higher that your projector air filter is full of dirt and debris.
But if you feel it will not be easier to clean the unit, then calling a professional to clean the filter would be the best idea.
If your projector is not under warranty, you can open up the unit and clean the air filter yourself, or you can also check out the video below.
Make sure Projector fan is not blocked
If your projector is new and your unit is still heating, the projector fan is not running correctly, or there is some problem with the internal component.
So, how will you determine whether the fan is working properly? Place your ear near the fan and hear the sound of a fan.
If the projector is running and a fan is not making any noise, then it is a 90% chance the projector fan is blocked or not working.
If the fan is damaged, then it will cause overheating of your projector, and the unit will shut down by itself. Also, never place any object near the projector because this might block the airflow, and the heat will not pass out.
If you want to extend the lifespan of the projector, then you must always keep it clean and dust-free as much as possible, especially air filters and cooling fans.
Use a cooling pad
If you want to ensure that your projector doesn’t shut down due to overheating, then always use a cooling pad.
The cooling pads are specially designed for the projectors to stop them from overheating because when air passes through it, then it cools the projector.
If your projector is placed on a table or tripod, place the cooling pad beneath the unit and connect it with the projector USB output.
They will not only reduce the heat but also increase the life of your unit.
Using External Fan
If you don’t want to spend money on a cooling pad, then you can use an external fan at the back of your projector.
While placing the fan behind the projector, the hot air is pushed outside, and cooler air enters inside for the cooling process.
This will also reduce the noise level when using movies or playing games, but after a few months, you will have to change the fan because the fan blades get rusted due to moisture from the air.
Also, there are chances that your room becomes hot and humid during the summer because of the heatwave outside, so use an external fan only if you don’t have other options.
How do I cool down my projector?
You can quickly cool down the projector and prevent it from shutting down by cleaning the air filter and removing dirt.
Also, attach a cooling pad to the bottom of your projector to make sure that the temperature won’t get too high because overheating is the primary reason for the projector’s malfunction.
How long does it take for a projector to cool down?
It depends on how much your unit is overheated. If your room has an average temperature, then it will take around 20 minutes to cool down the projector completely.
Why does the projector overheat?
Projectors get overheated mainly because of two reasons, one because of excess heating inside the room, and the second is dust which makes it work harder to cool down the projector.
So even if you have an air conditioner in your room or live in a colder climate, then still chances are there that projector will get overheated, so take care of extra heat sources to keep your projector safe.
Is it normal for a projector to get hot?
Yes, it’s 100 percent normal for the projector to get hot due to the high-power lumen bulb, which helps the unit project the image on the screen.
But if you feel that your projector is overheating, then try to open the unit and clean it completely only when your unit is in warranty. Else it is always recommended to call an expert.
