4. Indoor Blower Speed Out of Control Error

If the speed of your blower has increased too much or has decreased too much and you are not able to control it, then it shows an E3 error. If the blower speed of your Voltas AC is out of control, it could indicate a problem with the blower motor or the control board.


If the motor is damaged or faulty, it may cause the blower to run at high speed. Check the motor for any signs of damage or wear, such as frayed wires or burnt-out components. If you notice any issues, you may need to replace the motor. Also, check the air filter temperature sensor and control board thoroughly.

E4, 5-Time Blink

5. Indoor Coil Temperature Sensor Error

The E4 error on a Voltas inverter AC indicates a fault with the indoor coil temperature sensor. This could be due to a malfunction or a wiring issue with the sensor.


Check the wiring connections between the indoor coil temperature sensor and the control board. Also, check Check the indoor coil temperature sensor for any damage or signs of wear and tear. Clean the dirt obstructing the temperature sensor. This can help to improve the accuracy of the temperature readings.

E5, 6-Time Blink

6. Open or Short Circuit of Ambient Temperature Sensor Error

An E5 error on a Voltas inverter AC indicates an open or short circuit of the ambient temperature sensor. The ambient temperature sensor is a small device that measures the temperature of the air in the room and sends that information to the AC’s control board. When the control board detects an issue with the sensor, it will display an E5 error on the unit’s display.

An open circuit means that there is a break in the electrical connection between the sensor and the AC unit, while a short circuit means that there is a direct electrical connection between the sensor’s wires.


Wiring connections between the sensor and the AC unit to ensure that they are secure and not damaged. If there are any issues with the wiring, you may need to repair or replace it.

EC,7-Time Blink

8. Refrigerant Leak Error

If your Voltas AC is experiencing a refrigerant leak, it can cause an EC error. This error message indicates that the AC’s refrigerant level is either too low or too high, and the unit cannot operate properly.


A refrigerant leak is a serious issue and should be addressed by a professional technician. They will be able to locate and repair the leak and recharge the refrigerant.

P0, 1 Times Blink

1. Inverter Module Protection Error

The P0 error code on a Voltas AC indicates an inverter module protection error. This error can occur due to various reasons, including an overloaded compressor, defective inverter module, faulty outdoor fan motor, or improper installation of the AC unit.


Inspect the inverter module and compressor for any damage. If you find any damage, then replace the faulty component.

P1, 2 Times Blink

2. Overvoltage or Low Voltage Protection Error

The P1 2 error code on a Voltas AC unit typically indicates that there is a problem with the voltage supply. It can either mean that the voltage is too high or too low for the AC.


You can use a voltmeter to measure the voltage at the AC’s power input terminals. If the voltage is outside the recommended range, use a stabilizer.

P2, 3-Time Blink

3. Temperature Protection of Compressor Error

The P2 error code on a Voltas AC indicates that the compressor’s temperature protection mechanism has been activated due to an abnormal increase in the compressor’s temperature. This could be caused by several factors such as low refrigerant levels, a dirty air filter, a malfunctioning thermostat, or a faulty compressor.


Check the air filter to see if it is dirty or clogged. If it is, clean or replaces it to improve airflow. Verify that the fan motor is functioning correctly, as a faulty fan motor can cause the compressor to overheat.

P3, 4-time blink

4. Outdoor Temperature to Low Protection Error

If the refrigerant gas is less in your compressor then it shows a P3 error.  The temperature becomes very low which does not heat the condenser.


You can check for leaks in the refrigerant pipes and recharge the system with the correct amount of refrigerant.

P4, 5-time blink

5. Inverter Compressor Drive Error

The P4 error code on a Voltas AC indicates an inverter compressor drive error. This means that there is a problem with the component that drives the compressor, which is responsible for cooling the air in the AC unit. The exact cause of the error can vary, but it may be due to a faulty inverter circuit, a damaged compressor motor, or a problem with the electrical connections between these components.


Check the wiring connections between the inverter board and compressor motor to ensure they are properly connected. Test the inverter board and compressor motor using a multimeter to identify any issues with the components.

F0, 1-time blink

1. Overload Current Protection error

The F0 error code on a Voltas AC typically indicates an overload current protection fault. This error code appears when the current drawn by the AC exceeds the rated value, and the overload protection circuitry is activated to prevent damage to the AC.


Avoid overloading the AC by using it beyond its cooling capacity or running multiple appliances simultaneously. This can cause the AC to draw more current than it should, leading to the error code.

F1, 2-time blink

2. Outdoor Temperature Sensor Fault Error

The F1 error code on a thermostat typically indicates an outdoor temperature sensor fault. This sensor is responsible for measuring the outdoor temperature and communicating that information to the thermostat. If the sensor is not functioning properly.


Inspect the wiring connections between the outdoor temperature sensor and the thermostat to make sure that they are properly connected and not loose or damaged.

F2, 3-time blink

3. Outdoor Condenser Sensor Fault Error

The F2 error code on an air conditioning unit typically indicates an outdoor condenser sensor fault error. This error code means that there is a problem with the sensor that detects the outdoor temperature, which is necessary for the proper operation of the air conditioning.


Inspect the wiring between the outdoor sensor and the air conditioning unit for any damage or loose connections. Tighten any loose connections or replace any damaged wiring and sensor.

F3, 4-time blink

4. Discharge Pipe Sensor Fault Error

The F3 error code on a device typically indicates a Discharge Pipe Sensor Fault Error. This error code indicates that there is an issue with the discharge pipe sensor, which is responsible for detecting the temperature of the water as it leaves the device.


To resolve this issue, you should check the wiring connections between the sensor and the control board for any loose or damaged wires. If everything is connected properly and the problem persists, you may need to replace the sensor.

F4, 5-time blink

5. Outdoor EEPROM Parameter Fault Error

The F4 error code on an air conditioner indicates an issue with the outdoor EEPROM parameter. This could be caused by a faulty outdoor control board or a communication error between the indoor and outdoor units.


It may be necessary to call a professional technician to replace the faulty EEPROM.
