4 Ways to Fix E8 Error Code In Window Air Conditioner

The E8 error code in a window air conditioner indicates a malfunction within the unit that disrupts the cooling process, leading to an uncomfortable indoor environment. When this error code appears on your AC, it should not be ignored as it signifies underlying issues that require attention.

In this comprehensive guide, we will explore the common causes of the E8 error code in window air conditioners and provide you with step-by-step solutions to fix the issue. Understanding the reasons behind the E8 code and knowing how to troubleshoot it can save you time and money in the long run.

By the end of this guide, you will be equipped with the knowledge and confidence to identify and resolve the E8 error code in your window air conditioner.

4 Causes of E8 Error Code In Window Air Conditioner

1. Fan Motor Problems

One of the primary causes of the E8 error code in window air conditioners is issues with the fan motor. The fan motor plays a role in circulating cool air throughout the room, and when it malfunctions, it can trigger the E8 code on your AC unit.

Physical obstructions, such as debris, dust, or dirt buildup, can prevent the fan motor from operating smoothly, leading to the E8 error code. Over time, these obstructions can cause the fan motor to work harder, putting additional strain on the component and potentially causing it to fail.

Internal malfunctions within the fan motor, such as worn-out bearings or a faulty motor winding, can also hinder the fan’s performance, affecting air circulation and cooling efficiency.

It’s important to note that fan motors typically last between 10 to 15 years, depending on usage and maintenance. If your window air conditioner’s fan motor has reached the end of its lifespan, it may be more cost-effective to replace it with a new one rather than attempting repairs.

2. Faulty Sensor

Another cause of the E8 error code in window air conditioners is a faulty temperature sensor. The sensor is responsible for monitoring the cooling process and providing accurate temperature readings to the AC unit’s control board. A defective sensor may send inaccurate information, causing the air conditioner to disfunction and display the E8 error.

Physical damage to the sensor, such as corrosion or wear and tear, can impair its ability to monitor the cooling process correctly. When the sensor fails to provide accurate readings, the air conditioner may not function properly, leading to inconsistent cooling performance or complete shutdown.

3. Clogged Air Filter

A clogged filter is another common cause of the E8 error code in window air conditioners. As the air conditioner operates, the filter captures dirt, dust, and other airborne pollutants to maintain good indoor air quality. However, over time, these particles accumulate on the filter, restricting airflow within the unit.

When the filter becomes excessively dirty, the air conditioner struggles to draw enough air to keep the room cool. This causes the unit to overwork, consuming more energy and leading to higher electricity bills. The added strain on the compressor and other components can also reduce the air conditioner’s overall lifespan.

Moreover, a clogged filter can lead to poor indoor air quality, as the restricted airflow allows dust, allergens, and other pollutants to circulate in the room, triggering respiratory issues and allergies for occupants.

4. Incorrect Installation

Incorrect installation of an air conditioner can also lead to the E8 error code. When a technician makes mistakes during the installation process, particularly with the wiring, it can impair the unit’s functionality and cause operational issues.

Improper wiring can disrupt the communication between the air conditioner’s components, such as the compressor, fan motor, and control board. This can result in the E8 error code being displayed, indicating a defect within the system.

Furthermore, incorrect installation can lead to various other problems that affect the air conditioner’s efficiency and performance. For example, if the unit is not properly secured or leveled, it may vibrate excessively or fail to drain condensate effectively, leading to water leakage and damage to the air conditioner and the surrounding area.

To avoid the E8 error code and other issues stemming from incorrect installation, it is suggested to have your window air conditioner installed by a qualified HVAC technician.

How To Fix Code E8 Error?

If your window air conditioner is displaying the error code E8, don’t worry. We have put together a step-by-step guide to help you troubleshoot and fix error E8.

1. Safety Precautions

Before attempting any repairs, it’s important to prioritize safety. Start by turning off the air conditioner and unplugging it from the power source to prevent electrical shocks or injuries. When working on the unit, wear gloves and safety glasses to protect yourself from potential hazards, such as sharp edges or debris.

2. Consult the User Manual

Locate your air conditioner’s user manual and find the section that addresses error codes, specifically the E8 code. Follow any preliminary troubleshooting steps provided by the manufacturer, as they may have specific instructions for your model.

Note: In case you don’t have a user manual for your AC unit, follow these steps:

1. Visit Google.com
2. Type in the AC unit model number + manual + amazon.com
   1. for example, “GE Window Air Conditioner Unit manual amazon.com”
3. You will see your AC unit’s product page, click on that and navigate to “Product guides and documents”, you will find the user manual attached there, download it and go through it.

3. Check the Air Filter

A clogged filter is a common cause of the E8 error code. Inspect the filter for dirt, dust, and debris that might be restricting airflow. If the filter is dirty, clean it with water and allow it to dry completely before reinstalling it. If the filter is damaged or excessively dirty, replace it with a new one. Keeping your filter clean can lower your air conditioner’s energy consumption by 5% to 15%, saving you money on energy bills.

4. Inspect the Fan Motor

To inspect the fan motor, remove the front panel or casing of the air conditioner. Check for any physical obstructions preventing the fan from rotating freely. Manually rotate the fan to check it moves smoothly.

If the fan is stuck or difficult to turn, it may require lubrication or replacement. If you notice any damage to the fan motor or its wiring, contact an experienced technician for further assistance.

5. Examine the Temperature Sensor

Locate the temperature sensor, which is typically found near the evaporator coils or in the air outlet path. Inspect the sensor for any signs of physical damage or disconnection. If the sensor appears damaged, it may need to be replaced. Using a multimeter, check the sensor’s resistance and compare it to the manufacturer’s specifications to know it is functioning correctly.

6. Reset the Air Conditioner

If the above steps do not resolve the E8 error code, try resetting the air conditioner according to the manual’s instructions. This may involve pressing a specific button or combination of buttons. Alternatively, unplug the unit for a few minutes, then plug it back in and turn it on to see if the error code clears.

DIY Vs Professional Help

When faced with the E8 error code in your window air conditioner, you may wonder whether to attempt a DIY fix or seek professional assistance. DIY fixes can be cost-effective and allow for immediate action, especially for basic maintenance tasks like cleaning filters and checking for obstructions.

However, DIY repairs have limitations and risks, such as misdiagnosis, further damage, and safety hazards when dealing with electrical components.

Professional help is recommended if the E8 error persists after basic troubleshooting, as it may indicate a more complex issue requiring specialized knowledge and tools. HVAC technicians can accurately identify and address the problem, maintain warranty coverage, and ensure safety.

While DIY fixes can be tempting, it’s vital to recognize when professional expertise is necessary to repair your air conditioner correctly and efficiently. If you’re unsure or lack technical knowledge, it’s best to contact a qualified HVAC technician for assistance.
