Resolving the E3 Error on Your Dawlance Inverter AC
Seeing an E3 error code on your Dawlance inverter air conditioner? This code indicates an issue with the outdoor coil temperature sensor, a critical component that monitors the temperature of the condenser coil to ensure efficient cooling. Here’s a step-by-step guide to diagnose and fix the E3 error. If you need professional help, remember that Bulao.pk offers expert AC repair services to restore your unit to perfect working condition.
Understanding the E3 Error Code
The E3 error code points to a problem with the outdoor coil temperature sensor. This sensor is crucial for measuring the temperature of the condenser coil, which helps the AC regulate the cooling process efficiently. A malfunctioning sensor can lead to improper cooling and might cause the unit to shut down to prevent further damage.
Causes of the E3 Error Code
Faulty Sensor: The sensor might be defective or damaged.
Loose or Disconnected Wires: The wiring connecting the sensor to the control board could be loose or disconnected.
Dirty Sensor: Accumulation of dirt or debris on the sensor might cause malfunction.
Control Board Issues: Sometimes, the control board may have issues affecting the sensor’s performance.
Steps to Diagnose and Fix the E3 Error
1. Turn Off the AC:
Ensure safety by turning off the air conditioner and unplugging 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 temperature 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. Reassemble the Unit:
After resolving the sensor issue, reassemble the outdoor unit and plug the AC back in.
9. Test the AC:
Turn on the air conditioner to see if the E3 error code is resolved. Monitor the unit to ensure it operates correctly.
