6 Common Problems You Will Experience with a Split AC

Now that you know about the error codes, we should move on and find the six common problems that you will experience with a split AC in India.

Common Problems

#1 Refrigerant leakage

Leakages are fairly common in split ACs. The refrigerant or the AC gas is responsible for giving out cool air. If the AC is not giving cool air, it is possible that the refrigerant level is quite low. Refrigerants are stored at a high pressure, so the joints and curves in the copper pipe are under tremendous stress. When there is humidity, it is possible that the atmospheric corrosion-causing compounds will weaken the copper pipes. It causes leakage, but don’t stress as this can be fixed. Compare the service charges and then get it fixed by a technician. If you see an EC error code on your Voltas AC, it is a refrigerant leakage. Besides this, there are many reasons you could get an EC error.

#2 Compressor is switching off too often

This could happen due to choking of the filter. When dust or debris accumulates in the AC, you will find the compressor switches off frequently. You need to get the filter cleaned so that the AC does not have to work too hard to intake some air for circulation. You can take out the filter and keep it under tap water. You should be doing this on a monthly basis.

#3 Cooling Coil Ice Accumulation

If you see DF on your Voltas air conditioner, the cooling coil has iced up. It is a defrost notification, so you must take this seriously. Once the ice has completely cleared out, your air conditioner will start working again.

This happens when the refrigerant level is less than the specified or required amount. The temperature of the cooling coil drops below the normal temperature. When this happens, the moisture in your room condenses on the cooling coil and freezes.

#4 Foul smell coming from the AC

If you are getting a foul smell from your AC, it is the drainage system that is causing the issue. Due to debris and dust inside the drainage tray and pipe, the water collects and starts smelling poorly. You need a technician to fix this. They will clear out the drainage system and this will solve the issue.

#5 Split AC does not start

The PCB of your air conditioning unit is faulty. There is no specific reason why this happened. It could be the surge in current or the usual on-off cycle or the physical damage. If capacitors or ICs have burnt, you have got only one option which is to replace it. In case the damage is more, you need to change the whole PCB. Changing the PCB is expensive – it depends on the technology too.

Hot weather calls for AC fix – you can’t be sitting in a humid room, especially during daytime and sleep time.

#6 Indoor unit is making a lot of noise

The indoor unit of your split AC may start making peculiar noises while starting up or operating. The problem is not too big. It is possible that the fan inside is faulty. As you keep using the unit, the fan gets disbalanced. The technician will come to you and dismantle the indoor ac unit. They will arrange the fan and place it at the original place. At times the sound comes because of accumulation of dirt and dust. Dirt and dust causes vibration in the AC fan. Cleaning after dismantling can help.

There will be times when your AC swing stops working, it could be due to a fault in the motor. The second cause could be that the swing is controlled by separate wing motors.

What do you mean by E2 in Voltas AC?

If the air conditioning system gets an E2 error, it basically means that the outdoor unit has a sensor error. You can also detect an LED light that signals the error on the air conditioner. The issue comes when the evaporation temperature goes lower than the temperature under dry mode or cooling mode.

Why is my air conditioning not working?

If your air conditioning is not working, it could be caused due to various reasons. The common reasons include blocked or dirty air filters. There could be a problem with the refrigerant or compressor too.

How do I reset my Voltas AC without a remote?

What is the E5 error in Voltas AC?

E5 error is a communication error. It means that no feedback has been received from the outdoor unit to the indoor unit. It could also be due to faulty wiring, outdoor/indoor PCB failure, loose connection, and so on. You can get this checked by a professional.

Why is the AC light red?

The thermostat blinks or stays red when the compressor shuts down. If this happens, a signal is sent to the thermostat. But the indoor unit does not get a message so it continues to run.
