Initial Checks
Ensure the power supply is stable. A faulty power source can cause errors. Check if the outlet is working. Try plugging in another device. If the device works, the outlet is fine. If not, fix the outlet.
Inspect the circuit breaker. A tripped breaker may stop the AC. Go to your breaker box. Look for the breaker labeled “AC.” If it is off, switch it on. This may fix the issue. If it trips again, there may be a wiring problem.
Inspecting The Sensors
The temperature sensor helps control the air conditioner’s performance. It measures the air temperature inside the unit. If the sensor is faulty, it might give wrong readings. This can lead to poor cooling. Inspect the sensor for dust or damage. Clean it gently with a soft cloth. Replace it if it seems broken or worn out. A working temperature sensor ensures the AC runs efficiently.
The pressure sensor monitors the refrigerant pressure. It ensures the system works within safe limits. A faulty pressure sensor can cause the AC to malfunction. Check for any signs of wear or damage. Clean the sensor area to remove dirt or debris. Replace the sensor if it appears to be broken. A functional pressure sensor helps maintain optimal AC performance.
Resetting The System
To fix the error code 4220, start by doing a power cycle. First, turn off the air conditioner. Next, unplug it from the power source. Wait for about five minutes. Plug the air conditioner back in. Turn it on and check if the error code is gone. This method often fixes many common issues.
