6 Ways to Fix the Projector overheating issue

If we begin using projectors frequently and recklessly, overheating and several other issues can be faced.

If we begin using projectors frequently and recklessly, overheating and several other issues can be faced.

The projectors run at extremely high temperatures. When the built-in fans fail to regulate the temperature, overheating issues are normally faced.

Frankly, that’s one reason why projectors usually get heated. There are some other reasons as well.

The overheating is an alarming issue, if not addressed the projector can unexpectedly shut down, or worse the projector bulb age.

To prevent this from happening, it is often suggested to nip the evil in the bud.

It must not be forgotten that a solution can not be found out when the issue is not identified.

So, you have to figure out what exactly is causing overheating. Once the issue is identified, you can find the solution accordingly.

Here’s what you can do when you can do to normally resolve the overheating issue;

Ways to Fix the Projector Overheating Issue

The overheating issue can be annoying but fortunately, it’s the easiest one to fix. You can easily fix the overheating issue by;

  • Placing it in a well-ventilated room
  • Making the room less stuffy
  • Dusting the filter effectively
  • Placing the cooling pad under the projector
  • Placing an external fan
  • Unblocking the projector’s fan

1. Placing in a well-ventilated room

That’s the surest way to fix the issue.

If the projector is placed and used in a well-ventilated room, you might not have to face the overheating issue in the first place.

Look around and try to judge if the room is airy enough for the projector to be used or not? If the room is not airy, you have to move your little home theatre to a well-ventilated room.

Ventilation helps in regulating the temperature and the projector will stop overheating.

If the room is well-ventilated yet the projector gets overheated, take it as a sign to change the spot.

If this is the case, you have to find a spot closer to the fan or any other ventilation point.

Installing the projector in a well-ventilated spot will also help you in overcoming the annoying overheating issue.

The trick is that when the projector is placed in a well-ventilated room or spot, the projector cools down and the overheating issue gets resolved in a matter of minutes. It would not simply resolve the issue but prevent it from happening again.

2. Making the room less stuffy

It is suggested to install the projector in the room that is neither stuffy nor gets frequently used.

If the room is overly stuffed and gets used frequently, placing or keeping the projector in that room is not a fine idea.

If the room is stuffy and used frequently, you have two options.

Either remove unnecessary belongings and make the room less stuffy or change the room.

Since temperature regulation fixes the issue, making the room less stuffy will make the environment around the projector less warm.

The over-heating issue will surely be fixed if it is being caused by poor temperature regulation.

3. Fix the overheating issue by dusting the filter

The dirty or unclogged filter is another major reason why projectors get overheated.

Premature shutoff and reduced lamp life are the signs of a dirty or clogged projector filter.

If the dirty or clogged filter is contributing to overheating, cleaning the filter thoroughly and preventing it from getting dirty again would resolve the issue.

Overheating caused by dirty or clogged filters is just as common as poor temperature regulation.

Since projectors are required to be placed in a well-ventilated room, the dirt gets the filter dirty that leads to overheating.

To clean the filter, all you have to do is

  • Turn off the projector and allow it to cool down
  • Flip the projector over and spot the air filter under the lens
  • Take a small soft brush and take out the air filter tray
  • Sweep off all the dirt using the small soft brush
  • Place it when it is thoroughly cleaned
  • Turn on the projector and enjoy

4. Placing the cooling pad under the projector

Cooling pads have many names however we recognize them as “cooler pad” or “chill pad”.

These pads are designed and engineered for laptops, projectors, and other electronic devices that get overheated.

These cooling pads resolve the overheating issue by reducing the operating temperature.

If you do not want to face this overheating issue ever in the future again, we suggest you place the projector over the cooling pad in a well-ventilated room.

The vents and the cooling pad would regulate the temperature and keep the projector from being overheated.

5. Fix the overheating issue by placing an external fan

When the vents and cooling pad fails to keep the projector cool, external fans can be installed to prevent overheating.

Take a small fan and place it at the front or back of the projector and allow it to do its magic.

The room will get a little noisier but it would surely contribute to overcoming the overheating issue.

Remember! The external fan can only be placed at the front or back of the projector. Otherwise, it would not help resolve the issue.

6. By unblocking the projector fan

All recent projector models that have an active cooling system have fans to prevent overheating.

These projectors rarely get overheated for any reason other than a blocked projector fan.

The projector fan can be blocked by a decoration piece or any other small-sized accessory placed in front of the fan.

If this is the case, simply unblocking the fan will begin cooling down the projector. If the fan is kept unblocked, you would probably not even face the issue again in the future.

Conclusion

In brief, the projectors can easily get overheated if they are not placed near the vents, have dirty filters, and many other reasons. This issue can be resolved by placing the projector in a well-ventilated room, cleaning the dirty filter, adding an external fan, and placing a cooling pad under the projector.
