Do you have an EC error code on your Air Conditioning unit? No need to worry!
EC is a common error for AC units. It means that the refrigerant or coolant pressure is either too high or too low. It may be due to a lack of refrigerant or defective fan motors, PC boards, or capacitors.
What Does EC Mean On An Air Conditioning System?
EC stands for electronically commutated, which combines AC and DC voltage, combining the advantages of both technologies to create EC. It means that the motor runs on DC voltage, but comes from an AC power source.
The EC error code tells you that your equipment has a pressure limit or the R410A refrigerant level is low. In this case, you must first contact a certified HVAC technician to check the pressure. If the pressure matches the gray label on the side of the condenser, your system has insufficient refrigerant. Make sure that the refrigerant charge in the factory is sufficient to cover this distance. Otherwise, you will need to add refrigerant.
Causes Of EC Error Code :
- Refrigerant Leakage
- Bad Internal and External PCB
- Sensor
- Bad Connection
Several reasons can cause EC Error. The main problem is usually a leak somewhere in the system.
What Can You Do To Fix This Problem?
You can temporarily fix this problem by turning off the air conditioner from the power supply at the circuit breaker. Switch off the power for 10 minutes, then turn it on again. Now turn on the air conditioner. If the error code appears again, turn off the device, as this will cause further damage. It may cost you for a new AC installation in Nogales,AZ. If the error code does not persist, you need to contact a professional. Schedule an appointment with a pro as this is a temporary fix.
Steps To Fix EC Code:-
- Turn off and on the AC Unit again.
Turn off the unit and turn off the circuit breaker for 2-3 minutes. Turn it on again, and if the error persists, follow the next step.
- Check for refrigerant leakage.
When looking for a leak, see whether there is any oil around a joint or spot. There are many ways to detect leaks, including the use of soap and water.
Also, most HVAC technicians have a refrigerant leak detector, which emits a loud beep near the leak. If a leak occurs, it needs to be repaired. A refrigerant needs to be added again to the system. Add refrigerant by determining the amount consumed by the system and adding it in by weight using a scale.
- A sensor failure
If the sensor detects the sensor failure, an EC error will be generated. Loose connections can also cause the same result.
- A Bad indoor or outdoor PCB
A Bad PCB can also cause this error. Make sure to check all other parameters before replacing the board.
