Projector Overheating: Why It Overheats, And How to Fix it?

The projection technology has improved over the years, but still there are some areas that need to be addressed. The problem with the projector overheating is one of the things that need to be rectified. This blog discusses how the projector overheats and what you can do to prevent it from overheating.

In this article, I have explained why your projector overheating, the various causes behind it, and all the necessary steps to cool it down in simple, easy-to-follow instructions. Read this guide if you are currently facing any issues with your projector as well! What happens if it gets overheated?

Why does a projector overheat?

People who are using their projector in a small room with poor ventilation, or a bright room with no curtains, may have issues with projector overheating. Usually, projectors come with a cooling fan, so it is rare for these to overheat. However, if the projector is not placed in an area with appropriate ventilation, the room may become too hot for the projector to adequately cool itself.

What are the things to be done if your projector is overheating?

The first thing to do is to check whether the projector is overworked. If it is, stop using it for 30 minutes. If the problem persists, check whether the air filters are clogged.

If it is, clean them. If the filters are clean, unplug the projector and let it cool for 12 hours, then check it. Also, check whether all the fittings are firmly connected.

What are the reasons for a projector to overheat?

Projector overheating is one of the leading causes of projector failure, and it is not always easy to detect.. Here are 6 major  reasons for the projector to overheat:

1. Dirty air filter

Projector Overheating

The built-in air filter that comes with many projectors is designed to keep dust and dust-made debris from getting into the projector. When this filter gets dirty, it can cause the projector’s internal fan to work harder and heat up the projector. There are two types of air filters:

One that is located in the front of the projector, and one that is installed in the projector’s air intake. If you see dust or dirt coming from or around the air vents, then it is likely that the air filter is clogged.

2. Excessive ambient temperature

Ambient temperature is the temperature of the surrounding environment. Yes, an overheated projector can be caused by an excessively high ambient temperature. A projector is created to function in a well-ventilated area and in a temperature range of 5-35 °C. When the ambient temperature is higher than 35 °C, the projector is likely to overheat.

3. Defective cooling system

The projector’s cooling system is one of the most essential parts of the projector. This system keeps the projector from overheating and keeps it running at optimal levels.

If the projector has a defective cooling system, then the projector may overheat and shut down. This can lead to the projector being damaged, and it also poses a risk to the user of the projector.

4. Excessive voltage or poor grounding

Projectors run normally for a few minutes, then the fan kicks in, then the bulbs starts flickering, then the image gets blurry and finally the projector just shuts off. This is a typical scenario of what happens when the projector overheats. There are many reasons why a projector overheats.

One of the most common reasons is the voltage going into the projector is too much. Some consumers use adapters to power the projectors. The adapters produce heat that is not dissipated properly and cause the projector to overheat. It is always better to use the recommended voltage for your projector. Another reason could be the grounding of the projector. Make sure that the projector is grounded properly.

 5. Excessive use or lack of maintenance

It is a fact that all electronic devices get hot after prolonged use. But there are products such as projectors that get very hot in a short time. It is a bad sign when the projector is getting hot after a short time of use.

It is a sign that the projector needs to be repaired, or it is not being taken care of. If you own a projector, you should take good care of it. You should not let it overheat as it might cause permanent damage.

6. Projector Is Not Placed or Installed in a Well-ventilated Area

If your projector is not placed in a well-ventilated area, it can overheat, which can cause the projector to shut down. If your projector is not installed in a well-ventilated area, you should check that the air vents on the projector are not blocked.

If your projector is installed in a well-ventilated area, and it is still overheating, it may be due to a lack of air flow. Make sure there are no obstructions that are blocking the air flow.

What can you do to fix an overheating projector?

Projector Overheating

Most of the time, overheating issues in projectors can be solved with the help of a cooling kit, even if the projector doesn’t have in operating system.   A cooling kit comes in different designs, but they generally consist of a fan, heat sink and a heat sink lubricant.

The heat sink serves as a surface to dissipate heat from the projector.   The heat sink is located in front of the fan, with a heat sink lubricant to keep the fan from damaging the heat sink over time.   Since the heat sink can move, the fan is able to move air through the projector, dissipating the heat and allowing it to run longer without overheating.

Final thinking

The biggest cause of projector overheating is poor air circulation. Most projectors have fans that help exhaust the heat that the projector produces. However, if the projector is placed in an enclosed space, the heat will not be able to escape, and the projector will overheat.

This is why you should never place your projector in an enclosed space, such as a cabinet. Even if you have an air conditioner running in the room, you should never block the vents on the projector. Thank you for reading, we hope this information was helpful!
