Air conditioners are no less than a blessing in the hot summer of Dubai. However, despite all the maintenance and routine care, they can still malfunction sometimes. The seriousness of the malfunction can vary according to the type of error you get on your air conditioner. Although there are various types of errors and each error means a different thing, this article will revolve around the E4 error code which is related to your refrigeration system. You’ll learn the basic understanding of an E4 error code, the reason for it to appear on AC, and how to solve an E4 error in AC.
What is an E4 Error?
Let’s first get a basic understanding of the E4 error on an air conditioner.
E4 error is not really a threat to your system if it appears only once in a while. You can’t call it a malfunction as it is just an indication that your air conditioning system has ice formation on its evaporator coil and is defrosting for a while. The defrosting process itself isn’t a problem; however, it could mean that your air conditioner unit has some underlying problem that must be resolved to continue optimal functionality.
But what really happens when your AC enters defrosting mode? Well, one thing is clear: you can’t turn your AC in cooling mode while the defrosting is happening. Meanwhile, your AC will work with the fan only to humidify or dehumidify the air, but it won’t cool it. If the error keeps coming back, you should call in a HVAC technician to have a look at your system.
Also bear in mind that even though these error codes are similar in other air conditioners, they can mean a different thing in other ACs than yours.
Reasons for E4 to appear on your AC unit:
There can be many reasons for your AC unit to go into defrosting mode. Some of these reasons can be:
- Low Refrigerant: Your AC unit might be low on refrigerant for showing such signs. If that is the case, you should recharge the refrigerant to prevent this error.
We provide AC gas top-up services at a very minimal rate. Contact us to address the issue as soon as possible.
- Faulty Heat Pump: The problem can be with your heat pump or compressor. Your compressor might be unable to pressure the right amount of refrigerant hence causing the error. Faults with other HVAC components like expansion valve can also cause the issue.
- Block Air Filter: Changing Air filters regularly is necessary otherwise they can get blocked and restrict the airflow. Restricted airflow causes frosting on the evaporator coils leading to E4 error.
Some other reasons are:
- You have a Defective Steam Turbine.
- The HVAC unit has very high or very low Discharge pressure.
- The Weather around your area is chilly hence not suitable for Air conditioners or Cooling.
- Your thermostat has malfunctioned and is showing an E4 error.
- It can also be due to unsound temperature sensors.
These are some of the reasons you can inspect your Air conditioner to find the right one that’s causing E4 error.
How to solve E4 error in AC?
Here’s how you can fix the E4 error:
Check Freon Level:
You have to check your refrigerant in order to find the issue. If you have a gas gauge, you can use it to measure the level of refrigerant quickly. If not, then you can call in a professional to check it for you. If the gas level is low, you need to recharge it to smooth the working of an air conditioner.
By calling us, you’ll be saving yourself from the hassle of doing all the hard and tiring work. Refrigerant handling also needs skills and certain equipment. We will also inspect for any gas leaks and fix and seal them if we find any.
Clean/Replace the Air Filters:
As stated earlier, clogged or dirty air filters can restrict air flow causing frosting on the evaporator coil. You need to address the problem as soon as possible to solve the error. Clean your air filter if it is a reusable one. However, if your usable filter is over 3-4 months old, it’s time for a new one. Replace your air filter with a new one and see the difference.
Inspect Evaporator and Condenser Coils:
You can check your evaporator and condenser coils for any buildup of dirt, debris, and ice buildup. If found, clean it with a soft brush gently to solve the error.
Try operating your AC unit when an ample amount of power supply is available. Fluctuating power can cause the problem.
Consult a Professional:
If after doing all these things, the issue still persists then it’s time to call in a professional technician who can solve the problem by inspecting the issue thoroughly. Only qualified technicians should handle refrigerant repairs and complex electrical issues. We provide AC maintenance and repair services all over Dubai. You can trust us with your Air Con system as we’ll do a thorough inspection of your unit and keep you aware of the problems with your AC and their solutions.
In conclusion, E4 isn’t a serious issue, overlooking it for a long amount of time can cause serious issues in the long run. Many reasons can cause this error such as dirty air filters, low refrigerant levels, and faulty compressors. And you might be able to resolve some issues such as replacing an air filter or cleaning coils. However, refrigerant-related issues will need professional dealing with extensive care to avoid further problems. Also, remember to plug off your unit before attempting any of the above-stated solutions. Regular maintenance and timely repairs can keep your air conditioner running efficiently and save your AC unit from E4 errors.
