In Voltas Window AC units, an error code E2 typically indicates a problem with the temperature sensor or the indoor evaporator coil sensor. When this error occurs, it means that the unit is not reading the correct temperature, which can affect its cooling performance. To resolve the E2 error code in a Voltas Window AC, you can try the following steps:
Power off the AC: Turn off the air conditioner and unplug it from the power source. Wait for a few minutes to allow the unit to reset.
Check the sensor: Locate the temperature sensor inside the indoor unit. It is usually located near the evaporator coil or on the air inlet. Make sure the sensor is clean and properly connected. Check for any visible damage or loose connections. If you notice any issues, try to fix them or contact a professional technician for assistance.
Reset the unit: After inspecting the sensor, plug the air conditioner back in and power it on. Press the reset button on the control panel or use the remote control to reset the unit. This step can help clear the error code and recalibrate the temperature sensor.
Test the AC: Allow the air conditioner to run for some time and monitor its performance. Check if the error code E2 persists or if the cooling function has been restored. If the error code reappears or the cooling is still inadequate, it is recommended to contact a Voltas service center or a qualified HVAC technician for further diagnosis and repair.
Please note that the exact steps and solutions may vary depending on the specific model and features of your Voltas Window AC. It is always advisable to consult the manufacturer's manual or contact their customer support for accurate guidance on resolving error codes.
