Lloyd AC Error Codes List and Fixes (Split, Inverter)

Lloyd AC Error Codes and what they stand for can lead to an all-new understanding of the appliance. Air conditioners are a major part of our lives. However, there are differences between the brands and the subsequent products. But, at the end of the day, one must be able to understand what their ‘machine is trying to tell them. Essentially, this implies the fact that you need to ‘decode’ the error code in your Air conditioner.


With the technology on our side, it is increasingly a matter of being able to ‘decipher’ the machine talk. Now, Air conditioner units are no longer the tiring, bulky and noisy pieces of metal that throw out cold air. These are sophisticated home appliances that have been designed to serve the user in a manner that you can easily understand if something is not right with the normal working of the Air Conditioner. This way, the proper reading of the error code can help you with the following:

  • Easy and effective handling of the appliance.
  • Save money on unwanted services and repairs.
  • Quick fixes by self that allow the user to continue with the normal usage of the appliance.

Lloyd is one of the leading names when it comes to efficient cooling technology. Before we understand the Lloyd AC Error Codes, let us find out a bit more about the brand itself:

The Lloyd Air Conditioners

The Llyod company is owned by Havells India and is one of the best brands in electronics out here. The company was founded in 1956 by Fedders Llyod until it went solo in 2007. The company was acquired by the Indian company Havells in the year 2017.

Today Llyod is one of the most sought-after brands when it comes to manufacturing some of the best in electronics and home appliances. Likewise, the Llyod Air conditioners are one of the south-after names in the world when it comes to being able to offer the latest in solutions and high-tech features. It is known to be a pioneer in Cooling technology, bringing users some of the most user-friendly features. The new-age refrigerators, Air conditioners, TV, and washing machines.

With a wide range of some of the latest Air conditioners from the house of Llyod, the display of the Error code is one of the best aspects. This allows the user to self-diagnose the issue with their Air conditioner unit before calling upon a professional. So, let us find out more about Lloyd Air Conditioner Error Codes. 

Lloyd AC Error Codes List

Here is a list of some of the most common known Error Codes in Llyod Air Conditioners:

E1 – Indoor PCB Fault

This Error code implies the fact that there is an issue with the indoor PCB. This might mean that the PCB requires repair and replacement. As Llyod is known to offer a good warranty period, you can easily make the most out of it and get your PCB replaced or repaired.

E2 – High and Low Voltage Issue, Room Temperature Sensor Issue

When you have E2 flashing over the display, it implies that the input voltage is higher or lower than the operational range. For this, you can easily get an external Voltage stabilizer or simply wait for the voltage to stabilize. In case of a low voltage condition, you can utilize a double or triple Voltage booster and set the range to up to 220V.
In case of a room temperature sensor issue, one can easily get a Llyod professional service professional to replace the sensor. A case of loose connection can also result in this problem.

E3 – Indoor Fan Motor Problem, Pipe Temperature Sensor Fault

One of the best features of the Llyod Air conditioner is that it features an indoor fan which is also known as the Blower. This offers uniform cooling effects across the space, hence a better cooling experience. This is among the most common Lloyd Split AC Error Codes and requires you to summon the Llyod service professional. 

This error code implies the fact that there can be a problem with the Capacitor, and it might require replacement.

E4 – Defrost Mode, Room Temperature Sensor Fault (5-Time Blink), Outdoor Pipe Temperature Sensor Issue

This is not exactly an Error code but implies the fact that your unit is going into defrost mode. While the unit might not go to this mode automatically, however, there is a certain activity within the machinery that might lead to this problem. Some of the most common reasons are a broken temperature sensor which might require you to replace the same. However, after the defrosting is done, the error is rectified.

E5 – Cooling Coil Sensor Fault, Temperature Sensor Fault, Room Sensor Fault

This error code implies the fact that there might be an ill-fitted temperature or cooling coil sensor. The absence of the sensor altogether can also lead to an error. So, replacing the damaged sensor and ensuring it is well-fitted is recommended.

E6 – Indoor Coil Sensor Problem, Outdoor Malfunction

There is a Sensor located in the Llyod indoor unit as well. Hence, the sensor can trigger this Error code if there is a loose connection or a damaged indoor coil. So, to get rid of the error, you simply need to replace the damaged sensors. Checking if they are well fitted into the right socket is also a recommended solution to this error.

E7 – Condenser Coil Sensor Problem, EEPROM Malfunction

The condenser of the Llyod Air conditioner is located in the outdoor unit. Once again, this can imply the fact that there is an ill-fitting condenser coil that needs your attention. The solution is to get the condenser coil fitted well or replaced by a professional.

E8 – Low or High Voltage Problem or Water Level Alarm

The normal working Voltage range for the Llyod Air conditioner is between 160-220 V. In case the indoor voltage is higher than this range, the unit might stop working altogether. Hence, one can simply install an external Voltage stabilizer to solve this.
The other indicator of this Error code is related to the water level. The continuous blinking can refer to the fact that the water levels require professional attention.

E9 – Indoor to Outdoor Communication Problem

This Error code implies the fact that there is an electrical problem. To be more precise, it implies the fact that there is a lack of communication between the indoor and the outdoor unit. Hence, the AC fails to work problem. The replacement of wires can resolve this problem.

CL – Child Lock Activation

When you notice this particular Error code, it means that the Child Lock has been activated. To resolve this, simply release the lock and set the unit right.

DF – Defrosting Issue

This implies an error with the defrosting function. For this, you will need professional help.

H3 – A compressor Overload Issue

This error code implies that there is a problem with the compressor, probably, an overload issue. For this, you might need to get a professional.

P3 – Insufficient Refrigerant

This implies the fact that there is an insufficient Refrigerant in the unit. For this, you might need to check for leakage and repair them. After this, repair the gas and restart the unit.

P4 – Temperature Indicator Error

This implies the fact that there is a problem with the temperature indicator of the unit. The other reason can be that there is an inverter compressor is at fault. This is one of the most common Lloyd Inverter AC Error Codes. 

P9 – Display communication Fault

This error code implies the fact that there is a communication problem between PCB and the AC display. For this, you might want to get professional help.

PE – Pressure Switch Broken

This code refers to the indication that there is a breakage of the pressure switch. Hence you need to get professional help.

F1 – Non-Inverter AC Room Temperature Sensor Circuit Fault

This code refers to the fact that there has been a room temperature sensor circuit failure. For this, get a technician to come over to the checkout.

F2 – Non-inverter AC Evaporator Coil Temperature Sensor Circuit Fault

This code refers to the AC evaporator coil temperature sensor circuit problem. For this, you might need to replace the Sensors altogether.

H6 – IDU Fan Motor Fault in Non-Inverter AC

This implies the fact that there is a problem with the fan motor. Also, poor winding can lead to this problem. Get professional help for this issue.

E5 – Over Current Protection

This problem occurs due to the sudden surge in the input current. For this, you need to install circuit breakers.

E8 – Overload Malfunction

This problem occurs If and when there is an overload malfunction with your unit. For this, you will need to get professional help.

Lloyd AC Error Codes: The Conclusion

So, there you have it, people; these are some of the most prevailing Error codes that commonly occur in the Llyod Air conditioners. While most times, the codes allow you to know the problem, nevertheless, you need professional help as and when required.
