While using air conditioners, we often encounter issues like the perplexing EC error accompanied by a subtle ticking sound. What causes it, and how can it be resolved? Read on to unravel the mysteries of EC errors in air conditioners.
1. Decoding EC Error in Air Conditioners: Causes and Fixes
During the usage, we frequently come across issues such as the EC error and a ticking sound in air conditioners. What causes it, and how to fix it? Do you need to call a repair technician? Read this article to find answers to these questions.
Fixing Air Conditioner Issues for Optimal Performance
1. Resolving EC Error in Air Conditioners: Causes and Solutions
1.1. Understanding EC Error
EC error in an air conditioner is related to gas pressure, involving issues like gas leakage due to corrosion, insufficient gas, or pipes dented causing gas blockage. This error often renders the air conditioner non-functional. If it operates, it produces limited cool air, providing suboptimal efficiency for both large and small spaces.
1.2. Causes Leading to EC Error
The factors leading to EC error in air conditioners include fundamental reasons such as:
- Gas valve leakage due to gas corrosion
- Insufficient gas inside the air conditioner
- Denting or warping of pipes causing gas blockage
- Poor maintenance leading to gas airway obstruction.
1.3. Resolving EC Error in Air Conditioners
You should check the gas valve; if it's loose, secure it tightly. If damaged, replace it with a new one to ensure gas retention, influencing the cooling process and device durability.
- Measure the gas level remaining in the air conditioner and pump it up for stable operation, increased durability, and better equipment quality.
- Inspect the pipes, adjust any crimps or dents to allow smooth gas flow. When installing pipes, it's best to install them straight to avoid bends and curves that may affect gas flow paths.
- Regularly inspect, clean, and wipe the air conditioner to promptly detect issues, saving costs during usage.
So, when facing the situation of the air conditioner displaying an EC error, follow the troubleshooting steps mentioned above. If unsuccessful, seek assistance from technicians to examine technically challenging parts such as the compressor or ensure accurate and technically sound tube replacement for more efficient air conditioner operation.
2. Troubleshooting a Noisy Air Conditioner
2.1. When Does an Air Conditioner Make a Ticking Sound?
When the air conditioner makes a ticking sound, it may indicate issues such as weak cooling, low gas, or a faulty capacitor. It's essential to inspect the air conditioner when you hear this noise.
2.2. Causes and Solutions for Air Conditioner Making Ticking Noise
First: It could be due to the air conditioner running out of gas
- If your home's air conditioner lacks gas or runs out of gas due to leaks at connections, welds, gas corrosion on pipes, valves, or openings in the evaporator and condenser due to prolonged rust leading to tube punctures... Another case is during installation, if the air conditioner installer does not follow proper procedures, neglects checking and charging sufficient gas.
- The cause of the air conditioner running out of gas is the escape of refrigerant carrying oil through the coil. If the unit is dry and there are no signs of oil leakage, gas leakage is highly unlikely.
- Signs of identifying a gas-depleted air conditioner: Reduced cooling efficiency; snow buildup near the small tube valve of the condenser; in some units, when gas is low, the control panel will automatically shut down the unit after about 5-10 minutes and display an error on the condenser, or make a ticking sound.
- Remedy: Call a specialized repair technician to check. If there is gas corrosion, perform welding; if damaged, replace the gas valve for better air conditioner performance.
Cause 2: The air conditioner capacitor is burnt, and the circuit is damaged
- When the air conditioner runs continuously in hot weather, the legs at the heat-exchange end get hot, and some poorly insulated wires may break, causing the coil not to run, resulting in the air conditioner not cooling. In case of a capacitor error, the air conditioner will display an error and make a ticking sound.
- If it's a simple wire break, you can check and reconnect it yourself. You may not necessarily need to call a repair technician in this situation.
Pay attention to potential cases:
- When the air conditioner circuit malfunctions, the indicator on the air conditioner's cooling unit will flash yellow at the Timer button (for older models) or the light will continuously blink (for newer models). However, sometimes it's not a faulty circuit board; the issue could be a broken sensor wire, and the machine signals an error.
Resolving the air conditioner error with a buzzing sound due to circuit issues
- In some advanced air conditioners, you can independently check the machine's errors right on the control panel. Press and hold the Cancel button, and it will display each error. When an error appears, and the air conditioner makes a long buzzing sound, you can search online to identify the specific issue. This way, you'll have a clear understanding of your air conditioner's problem, avoiding potential deception by repair technicians.
Third Cause: Air conditioner weak, insufficient cooling
When encountering this issue, some air conditioners with a buzzing sound may signal an error. In this situation, what you need to do is:
- When you've been running the air conditioner for a long time, setting the temperature very low, but the room remains warm. The most common cause is a dirty filter, with dust obstructing the airflow, making the room less cool, and the air conditioner consuming a lot of electricity.
- First, remove the outer plastic cover of the air conditioner and take out the filter. You can use your hand or a paintbrush to remove the dust before rinsing it thoroughly (spray water from the front to the back of the filter, as dust on the front side will be easier to wash away). Dry the filter thoroughly and shake off any remaining water before reinstalling.
