Resolving the P3 Error on Your Dawlance Inverter AC

If your Dawlance inverter air conditioner is showing a P3 error code, it indicates an outdoor unit overload protection issue. This problem can severely affect the performance of your AC and may lead to further damage if not addressed promptly. Here’s a comprehensive guide to diagnosing and fixing the P3 error. For professional assistance, remember that offers expert AC repair services to restore your unit to optimal condition.

Understanding the P3 Error Code

The P3 error code signifies that the outdoor unit of your AC is experiencing an overload. This protection mechanism is designed to prevent damage to the system by shutting down the unit when it detects excessive load or overheating.

Causes of the P3 Error Code

  1. Dirty Condenser Coils: Accumulation of dirt and debris on the coils reduces cooling efficiency.
  2. Blocked Airflow: Obstructed airflow around the outdoor unit can cause overheating.
  3. Electrical Issues: Problems with the power supply or electrical components can lead to overload.
  4. Faulty Fan Motor: A malfunctioning fan motor in the outdoor unit can cause overheating.
  5. High Ambient Temperature: Extremely high outdoor temperatures can overload the system.

Steps to Diagnose and Fix the P3 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. Inspect and Clean the Condenser Coils:

  • Locate the condenser coils in the outdoor unit.
  • Clean the coils using a soft brush or coil cleaner to remove dirt and debris. Be gentle to avoid damaging the fins.

3. Check for Obstructed Airflow:

  • Ensure that there are no obstructions around the outdoor unit. Clear any debris, leaves, or objects blocking the airflow.
  • Maintain a minimum clearance of two feet around the unit for optimal airflow.

4. Inspect the Fan Motor:

  • Check the fan motor for any signs of malfunction. Listen for unusual noises and ensure the fan blades are spinning freely.
  • If the fan motor is faulty, it may need to be repaired or replaced by a professional.

5. Verify Electrical Connections:

  • Inspect all electrical connections to ensure they are secure and there are no signs of wear or damage.
  • Use a multimeter to check the voltage and current to ensure they are within the recommended range.

6. Monitor Ambient Temperature:

  • Be aware of the outdoor temperature. If it is extremely high, consider using the AC during cooler parts of the day.
  • Ensure the AC unit is adequately shaded without blocking airflow to help manage high ambient temperatures.

7. Inspect for Faulty Components:

  • Check other components, such as capacitors and relays, for any faults that could contribute to the overload.
  • Replace any faulty components as necessary.

8. Reassemble and Test the Unit:

  • After cleaning and inspecting the components, reassemble any parts that were removed.
  • Plug the AC back in and turn it on. Monitor the unit to see if the P3 error code is resolved.
