Spring is in the air, and with warmer weather on the way, one thing for many homeowners – air conditioning season is just around the corner! If you’re like most people, your air conditioner is a critical part of your home’s comfort system.
So what do you do if it starts giving you trouble? This blog post will talk about all the information related to the e8 error code and show you how to fix it on your air conditioner. Keep reading to learn more!
What is E8 error code in an Air Conditioner?
E8 is an error code that may indicate an overload malfunction in your air conditioner. This error typically occurs when the unit becomes too humid and causes the fan motor to overload, resulting in a breakdown of system functionality. Areas with a humid climate are also prone to compressor overload protection errors.
Other possible causes of this error code include clogged or ruptured condenser coils, improper installation, or damage to the control board or other internal components.
If you are experiencing E8 errors on your air conditioner, it is best to consult a professional to help diagnose and resolve the issue quickly and safely. While waiting for repairs, you can take measures such as using a dehumidifier to prevent overloads from occurring again in the future.
Ultimately, by diligently maintaining your air conditioner and addressing any issues as soon as they arise, you can help prevent overload malfunctions and ensure long-term efficiency and reliability for your system.
What Causes an E8 Code on an Air Conditioner?
Several factors contribute to an E8 code on an air conditioner. Below is a list of the most common causes of an e8 code on an ac;
Dirty Indoor Air Filters
Dirty air filters can restrict airflow to your AC unit, causing it to overheat and trip the E8 code. Check your air filter at least once a month and replace it as needed.
Low Refrigerant Levels
Low refrigerant levels can cause an AC unit to trip the E8 code. If your refrigerant level is low, this may mean that your AC system is leaking or that the compressor is faulty.
Faulty Thermostat Sensor
Another potential cause of an E8 code on an ac unit is a faulty thermostat sensor. If the sensor isn’t working correctly, it won’t be able to detect when the temperature has reached its desired setting accurately. As a result, the indoor unit will continue to run to reach the desired temperature.
Clogged Condenser Coils
Over time, dust and debris can accumulate on the condenser coils, restricting airflow and causing the ac to overheat.
The wires connecting the various parts of your AC unit can become loose or damaged over time. This can cause a loss of power to the unit, resulting in overheating and tripping the E8 code.
Faulty Fan Motor
The indoor fan motor is responsible for circulating the coolant throughout your AC system. If it’s not working correctly, it will not be able to achieve the desired temperature, resulting in overheating.
Blockage at Outdoor Fan Motor Assembly
The outdoor fan motor assembly blockage can also trigger an E8 code. This is most often caused by debris accumulated around the fan or blades of the assembly.
Malfunctioning Control Board
The control board is the computer that controls all functions of your AC unit. If it malfunctions, it can cause the E8 code to be triggered.
How to Troubleshoot an E8 Error Code
Knowing how to troubleshoot an E8 error code on your device is essential. This will help you quickly and efficiently address any issues you encounter with your device. Below are a few tips you can troubleshoot an e8 error code;
Check Fan blowers on indoor and outdoor units.
A dirty or damaged fan could cause the e8 error code on your device. Check the indoor or outdoor unit blower fans to ensure they are clean and not damaged.
Check indoor unit air filters.
Air filters play an essential role in keeping your device working correctly. If they become dirty or clogged, this can trigger the e8 error code on your device. Check the air filter regularly and replace it if necessary to keep your unit running smoothly.
Check refrigerant level
If you notice an issue with cooling performance, check the refrigerant level on your indoor unit to see if there is a problem. Low refrigerant levels could be causing the e8 error code on your device.
Check fan rotation
Fan speed malfunction can trigger the e8 error code on your device. Check to ensure that the fan is spinning freely and no obstructions prevent it from rotating properly.
Check the PCB board.
The printed circuit board (PCB) is crucial for your air conditioner. If it becomes damaged, this can trigger the e8 error code on your device. Common faults that can damage the PCB include power surges and water damage.
Check the fan motor wiring.
Damages to wiring can occur over time due to corrosion or other factors. If the fan motor wiring is damaged, this can also trigger the e8 error code on your device. Check the fan motor wiring for any damage and replace it if necessary to fix the issue.
Check the thermostat
If the thermostat is not calibrated correctly, this could lead to the e8 error code being triggered. Check the thermostat and calibrate it if necessary to address the issue.
How to Fix E8 Error Code Air Conditioner
You will need to take some basic steps to repair any underlying issues contributing to this problem. Below are a few ways to fix an E8 error code on a portable air conditioner or Gree air conditioner (mini-split/ductless air conditioner).
- Reset the air conditioning unit
Resetting the air conditioning unit is the first step you should take when fixing this error code. This enables power cycling in both indoor and outdoor units. Turn off the ac unit and the breaker switch that controls the AC. Wait a few minutes, then turn on the breaker switch to power up your air conditioning again.
- Fix the PCB Board
The printed circuit board (PCB) is located inside the air conditioner. This is the unit’s “brain” that helps control all operations. This board can cause an E8 error code if something is wrong. You will need a professional look at the PCB board to diagnose and fix any issues.
- Clean or Replace the Air Filter
One common reason for an E8 error code is a dirty or clogged air filter. The air filter helps to protect the AC unit from dirt, dust, and other debris. Over time, the air filter can become clogged with these particles, which can restrict airflow and cause the AC unit to overheat. To fix this problem, simply clean or replace the air filter.
- Seal Refrigerant Leaks
Refrigerant leaks can occur for various reasons, such as loose connections, cracks in the coils, or damaged hoses. To fix this problem, you will need to have a professional repair any leaks and recharge the AC unit with refrigerant.
- Clean the Evaporator Coil
The evaporator coil helps to remove heat from the air inside your home. If this coil becomes dirty, it can cause the AC unit to overheat and display an E8 error code. To clean the evaporator coil, remove it and clean it with a soft brush. You may also need to use a cleaning solution designed specifically for coils.
- Fix the Wiring
Wiring problems can be caused by various factors, such as rodents chewing on the wires or loose connections. You will need a professional to inspect the circuit breaker box and repair any damaged wiring.
- Replace the Thermostat
In most cases, the thermostat will need to be replaced to fix an e8 error code. However, you may be able to fix some common issues with the thermostat, such as incorrect settings or a dead battery.
- Drain excess water
If your AC unit has a bottom tray, it is vital to ensure that there is no water buildup or excess moisture. Move the portable air conditioner to a suitable drain location and drain the overflow pan periodically.
