Kenwood P4 Error: Indoor Unit Overload Protection

Understanding the P4 Error

The P4 error code on your Kenwood inverter air conditioner indicates an overload protection issue with the indoor unit. This typically means that the indoor unit is experiencing an electrical overload, which can lead to potential damage if not addressed promptly.

Causes of the P4 Error

1. Electrical Overload: Excessive power is drawn from the indoor unit.
2. Blocked Air Filters: Dirt and debris block the air filters, causing the unit to work harder.
3. Faulty Blower Motor: Issues with the indoor blower motor can cause the unit to overheat.
4. Restricted Airflow: Obstructions in the airflow can lead to overheating.
5. Refrigerant Issues: Low or excessive refrigerant can cause strain on the system.

Detailed Solutions

1. Check for Electrical Overload

• Step 1: Turn off the power to the air conditioner.
• Step 2: Inspect the indoor unit for any signs of electrical damage, such as burnt wires or connectors.
• Step 3: Use a multimeter to check for proper voltage and current.
• Step 4: If there is an electrical issue, it is recommended to contact a professional technician to address it.

2. Clean or Replace the Air Filters

• Step 1: Turn off the power to the air conditioner.
• Step 2: Open the front panel of the indoor unit to access the air filters.
• Step 3: Remove the air filters and inspect them for dirt and debris.
• Step 4: Clean the filters with water and allow them to dry completely, or replace them if they are too dirty or damaged.

3. Inspect and Replace the Blower Motor

• Step 1: Turn off the power to the air conditioner.
• Step 2: Remove the protective cover of the indoor unit to access the blower motor.
• Step 3: Check the blower motor and fan for any signs of wear or damage.

• Step 2: Ensure that the air intake and outlet are not blocked by furniture or other items.
• Step 3: Keep the area around the indoor unit clean and free of dust and debris.

5. Check and Adjust Refrigerant Levels

• Step 1: Use a manifold gauge to check the refrigerant levels.
• Step 2: If the refrigerant is low, locate and repair any leaks before refilling.
