Epson Projector Overheating? (7 Steps to Cool It Down!)

If your Epson projector overheating you shouldn’t be worried. This is a common problem!

So, by default, multimedia projectors have a slightly higher work temperature compared to other electronics of similar sizes.

Epson has an in-built temperature margin, which when exceeded, causes the projector to enter an “Overheating” regime and enable all safety systems available.

Here’s what to attempt to reduce the temperatures:

Whenever the Epson projector is overheating, reduce your environmental temperature, check the vents, and clean the air filter. If the issue persists, factory reset the projector and check for issues with the power supply. 

That’s only a small part of what we have prepared so keep reading!

Why Does the Epson Projector Keeps Overheating?

Here’s what can potentially cause the Epson projector’s hardware to overheat:

How to Tell if the Projector is Overheating?

All Epson projectors are designed to notify for an elevated temperature of the hardware with a single indication – a solid red light that stays on.

Unlike a projector or lamp issue where the indicator blinks rapidly, a solid red is an indication of an ongoing overheating of the hardware.

The “Safety System” of the Epson projector will immediately turn off the device if the hardware reaches an unbearable temperature for the internal components.

So, the system is designed to preserve the functionality of the projector hardware pieces in case of prolonged overheating.

Epson Projector Overheating – Tested & Working Solutions

Tip: Follow the instructions in a consecutive order!

1. Clean Epson’s Air Intake Vents

The air intake vents or “ventilation openings” of Epson are what the projector uses to draw air from the outside and cool down the internal components.

With the assistance of an internal fan, the air is sucked into the vent compartment and spread through all components of the projector.

You must ensure that there are no obstructions on the vents, solid or not solid, and clean the openings on each side of the projector.

Bonus Tip: Clean the Projector’s Surroundings:

Dusty surroundings often contribute to the accelerated accumulation of dust particles in the projector’s vents, due to the fan’s rotary movement.

To ensure the periphery of your projector stays free of dust for as long as possible, position the Epson projector in a dust-free location.

Note: The Epson projector has a total of two ventilation openings on the side and back panel!

2. Reduce the Room’s Temperature

All electronics and technical devices’s hardware temperature tends to elevate proportionally with the environment temperature.

The higher the temperature in the projector’s room is, the better the chance for Epson to overheat or continuously function at unhealthy hardware temperatures.

Here are some recommended methods to maintain proper environmental temperature!

Air Out the Projector’s Room

The most basic but effective method for maintaining proper projector temperature is airing out your room often.

Utilizing the projector for extended periods without allowing fresh air to come in is the main contributor to the prolonged overheating sessions.

Move Nearby Heat Conductors

You should be always on notice for heat conductors close to the Epson projector, especially during the winter season.

If a direct heat stream is produced by a nearby heat conductor, such as a heater, furnace, or fireplace, the projector’s internal temperatures will be highly elevated.

Block Off the Direct Sunlight

You should be always on the lookout for direct sunlight shining on the surface of your projector.

Direct sunlight can elevate the projector’s temperature very quickly and very highly, resulting in emergency shutdowns, reboots, or potential damage to the hardware.

3. Uninstall & Clean Epson’s Air Filter

Unlike the ventilation openings, you must access the projector’s hardware to remove the air filter and clean it from debris and dust accumulation.

This is a standard procedure in maintaining the projector and must be done every once in a while, even if the Epson’s temperatures are optimal.

Follow these instructions to access and uninstall Epson’s air filter:

1. Hold the projector’s “Power” button on the top.
2. After 10 seconds, unplug Epson’s power cord.
3. Find your air filter cover right behind the vent.
4. Hold the release tab to get the Epson air filter.
5. Pull out your filter from the projector’s socket.
6. Use a microfiber cloth or running water to clean.
7. Wait for your projector air filter to fully dry out.
8. Install the filter into the filter socket of your unit.

Bonus Tip: Replace Epson’s Air Filter:

A used-up or worn-out filter may impact the amount of fresh air your Epson projector draws in during broadcasting sessions.

As a result of the defect, the device may start overheating even if the air filter is clean, inserted properly, and doesn’t have any debris.

If that’s the case, the only solution for the projector is to install a brand-new air filter compatible with Epson’s socket.

Note: You can use a V13H134A32 replacement air filter to replace Epson’s original one!

4. Power Reset the Projector Unit

Yet, another cause for the Epson projector overheating problem is voltage overdrive, which supplies more power than necessary.

Connecting your projector to a powerful electrical source or third-party devices may increase the amount of voltage, causing the temperature to increase.

The solution would be to perform a power reset, which is a harmless, yet very effective method!

Follow these instructions to perform a power reset on Epson:

1. Hold the “Power” button on the projector for 10 seconds.
2. Disconnect the power cord from the back of your Epson.
3. Next, unplug the other end of the wire from the A/C outlet.
4. Wait for 45–60 seconds while the projector is discharging.
5. Reinstall the supplying cable of the projector on both ends.
6. Next, turn on the Epson projector and test the functionality.

Tip: Inspect the condition of Epson’s adapter while power cycling the device.

5. Factory Reset the Epson Projector

If you’re still able to interact with the Epson projector regardless of its temperature, you should activate a factory reset.

There might be a background process that you’re unaware of, which causes the projector to overheat due to extensive usage, which is apparent, but unnecessary.

Warning: Restoring the projector to defaults will erase all existing options and settings!

Here’s how to perform a factory reset on the Epson projector:

1. Press “Home” on the Epson remote control.
2. Next, navigate to the settings icon at the top.
3. Select “Device Preferences” from the listings.
4. Choose “Reset” and confirm the pop-up page.
5. Select “Enter” to start resetting your projector.

Based on the performance and the current temperature of the HW, your projector’s restoration may take up to 2–3 minutes to process.

Well, during that time, cease all interactions with the projector, do not press any of the panel buttons, and keep track of the hardware’s temperature.

Alert: Epson may power off amidst the reset if the temperature keeps increasing.

6. Inspect Epson’s Internal Fan

While inspecting Epson’s fan can be a challenging procedure even for someone with technical knowledge, you should still check if there’s a rotary movement. 

You can quickly and easily access the hardware of the projector by undoing the 8 screws on the bottom compartment.

The fan is on the outer casing of the Epson projector, so you must be able to immediately check whether it is spinning or whether its electrical cable is connected securely.

Warning: Do not uninstall the Epson projector if the warranty is still active.

7. Cool Down the Projector Externally (Workaround)

A more of a workaround rather than a direct solution is to set up external ventilation for your Epson device to elevate the heat.

Multimedia projectors function at high hardware temperatures by default, so reducing the temperature of Epson externally is a strong alternative if the internal fan isn’t sufficient.

These methods can be extremely efficient, especially during the warmer seasons, when there isn’t much you can do against high room temperatures.

Here are the top methods for cooling the Epson projector externally!

Use a Cooling Fan

The most efficient method for cooling the Epson projector externally is to set up a third-party fan or a ventilation system right next to the projector’s vent openings.

So, this is a standard method to lend a helping hand to the projector’s internal fan in reducing Epson’s temperatures.

Simply, install a small fan, blowing against the ventilation openings of your Epson projector, which will guarantee that the device will never overheat again.

Install a Heat Sink

The heat sink attachment will not cool the Epson projector externally by itself but works in great combination with any air conductor, cooling fan, or vent system.

For best efficiency, install a heat stick on the projector’s casing and verify the external fan is blowing against it for cool airflow.

Install a Thermal Electric Cooler (TEC)

A more advanced method involves setting up a thermal electric cooler (TEC) or more casually “Peltier” cooler on the surface of the projector.

Well, the device transfers the heat away onto the Epson projector’s side whenever an electric current passes through the metallic soldered plates.

Note: You can manage the heat of the projector by adjusting the external fan’s RPM.

Quick Recap

If the Epson projector overheating, power cycle the device and check for issues with the power supply.

If the overheating persists, clean the air filter, remove obstructions from the vents, and perform a factory reset on the projector. Follow us for more!
