Solving Gree F4 Error – Outdoor Coil Sensor Error

Encountering an F4 error code on your Gree inverter air conditioner? This error signifies an issue with the outdoor coil sensor, a crucial component that monitors the temperature of the condenser coil to ensure efficient cooling. Here’s a detailed guide to diagnose and fix the F4 error. If you need professional assistance, remember that Bulao.pk offers expert AC repair services to restore your unit to optimal working conditions.

Understanding the F4 Error Code

The F4 error code points to a problem with the outdoor coil sensor. This sensor is essential for measuring the temperature of the condenser coil, helping the AC regulate the cooling process efficiently. A malfunctioning sensor can lead to improper cooling and potentially cause the unit to shut down to prevent further damage.

Causes of the F4 Error Code

  1. Faulty Sensor: The sensor might be defective or damaged.
  2. Loose or Disconnected Wires: The wiring connecting the sensor to the control board could be loose or disconnected.
  3. Dirty Sensor: Accumulation of dirt or debris on the sensor might cause malfunction.
  4. Control Board Issues: Sometimes, the control board may have issues affecting the sensor’s performance.
  5. External Factors: Extreme weather conditions or external damage to the outdoor unit.

Steps to Diagnose and Fix the F4 Error

1. Turn Off the AC

For safety, turn off the air conditioner and unplug it from the power source before starting any inspection or repair.

2. Access the Outdoor Unit

Open the cover of the outdoor unit. You may need a screwdriver to remove the screws securing the cover.

3. Locate the Coil Sensor

Find the outdoor coil sensor, typically located near the condenser coil inside the outdoor unit.

4. Inspect the Sensor

Check if the sensor is properly connected to the control board. Look for any loose or disconnected wires.

5. Clean the Sensor

If the sensor is dirty, gently clean it with a soft cloth to remove any dirt or debris.

6. Test the Sensor

If you have a multimeter, test the sensor’s resistance and compare the readings with the specifications provided in the user manual.

7. Reconnect or Replace the Sensor

If the wires are loose, reconnect them securely. If the sensor is found to be faulty, it might need to be replaced with a compatible one from a reliable supplier.

8. Check the Control Board

Inspect the control board for any visible signs of damage or malfunction. If there are issues with the control board, it may need to be repaired or replaced by a professional.

9. Reassemble the Unit

After resolving the sensor issue, reassemble the outdoor unit and plug the AC back in.

10. Test the AC

Turn on the air conditioner to see if the F4 error code is resolved. Monitor the unit to ensure it operates correctly.
