Godrej split and window ACs display error codes on the indoor unit when a sensor, fan, or compressor fault is detected, helping users spot problems early.

These differ from protection codes like dF (frost protection) or H6 (fan motor protection), which are safety cutoffs the AC triggers on its own to prevent damage, not actual faults.

This guide covers both inverter and fixed speed Godrej Split and Window AC models, based strictly on official Godrej user manuals, so Indian users can quickly identify the issue before deciding whether a simple restart helps or a technician visit is needed.

Godrej Fixed Speed (Non-Inverter) AC Error Code Explanation With Solutions

dF – Frost Protection

What Causes This Error: The AC’s frost protection feature activates when the evaporator coil gets too cold, usually due to low airflow, a dirty filter, or low refrigerant.

How to Fix The Error: Turn off the AC, clean or replace the filter, and check that airflow is not blocked. If frost keeps forming, call a technician to check the refrigerant level.

E1 – Room Sensor Error

What Causes This Error: This appears when the room temperature sensor is short-circuited or has an open connection, so the AC cannot read the room temperature correctly.

How to Fix The Error: Restart the AC after 10 minutes. If the error returns, a technician needs to inspect or replace the room sensor.

E2 – Evaporator Sensor Error

What Causes This Error: This occurs when the evaporator coil sensor is short-circuited or open, preventing accurate coil temperature readings.

How to Fix The Error: Restart the unit and clean the filter and coil. If the error persists, the sensor likely needs replacement by a technician.

E3 – Condenser (Outdoor Coil) Sensor Error (Heat mode only)

What Causes This Error: This happens when the condenser coil sensor is short-circuited or open, mainly noticed during heat mode operation.

How to Fix The Error: Restart the AC and check the outdoor unit is not blocked or dusty. Persistent errors need a technician visit for sensor replacement.

E5 / H6 – Indoor Fan Motor Protection

What Causes This Error: This triggers when the indoor fan motor has a fault, causing the compressor and fan to shut off immediately as a safety measure.

How to Fix The Error: Turn off the AC, check nothing is blocking the indoor fan, and restart. If the fan does not spin freely, call a technician to check the motor.

U8 – Zero Cross Detection (Selected models only)

What Causes This Error: This code appears when the AC’s zero-crossing detection circuit, used for fan speed control, malfunctions.

How to Fix The Error: Restart the AC. If the code continues to appear, the indoor PCB needs professional inspection.

HF – Outdoor Unit Frost Protection (Heat mode only, selected models only)

What Causes This Error: This is a normal protection response when the outdoor coil frosts up during heat mode operation.

How to Fix The Error: This is usually part of the normal defrost cycle. If it triggers too often, have a technician inspect the outdoor unit.

HP – Indoor Coil Overheat Protection (Heat mode only, selected models only)

What Causes This Error: This activates when the indoor coil overheats during heat mode, often due to restricted airflow.

How to Fix The Error: Turn off the AC, let it cool, and check for blocked airflow around the indoor unit. Call a technician if the issue repeats.

Troubleshoot for Most Common Godrej AC Problems

AC does not operate immediately after being restarted

This happens because the compressor has a built-in overload protection delay. It is completely normal, and the AC will restart on its own after about 3 minutes.

Unusual smell coming from the indoor unit

The AC itself does not produce odors. The smell usually comes from dust, smoke, furniture, or other odors that have accumulated inside the unit. Clean the air filter, and if the odor persists, have the indoor unit professionally cleaned by an authorized service center.

Water-flow or gurgling sound during operation

This sound is caused by refrigerant flowing inside the system as the compressor starts, stops, or operates. It is a normal operating condition and does not need any action.

Mist coming out of the air outlet in Cool mode

This can happen when room temperature and humidity are very high, causing rapid cooling of room air to condense into mist. Continue operating the AC, and the mist will disappear as room temperature and humidity decrease.

Creaking or cracking noise when the AC starts or stops

This noise is caused by plastic components inside the unit expanding and contracting due to temperature changes. It is normal and does not indicate a fault.

The air conditioner does not run

Check whether the power supply has been switched off, the plug is loose, or the circuit breaker or fuse has tripped. Also verify the supply voltage is not too high or too low, and confirm the TIMER function has not been set incorrectly.

Cooling or heating performance is poor

Check that the temperature setting is appropriate, the fan speed is not too low, and the indoor and outdoor vents are not blocked. Dirty filters, open doors or windows, and heat sources inside the room can also reduce performance.

Wireless remote control does not work

Unplug the AC, wait briefly, and reconnect the power, as electrical interference can temporarily affect the remote. Also check that the remote is within range, its batteries are not weak, and it is not physically damaged.

Water leaking from the indoor unit

This can happen due to high indoor humidity causing condensation, condensate water overflow, or a loose or disconnected drain pipe connection. Check the drain pipe connection first, and contact a technician if the leak continues.

Water leaking from the outdoor unit

This is usually caused by condensation on refrigerant pipes during cooling, melted frost during automatic defrost, or condensed water from the outdoor heat exchanger during heating. These conditions are generally normal and do not need any action.

Noise coming from the indoor unit

Clicking sounds may come from the fan or compressor relay switching on and off, while refrigerant flow and fan noise can occur during defrost operation. These are normal operating sounds and do not indicate a fault.

Indoor unit does not blow air (Heat & Cool models only)

In HEAT mode, the indoor fan stays off until the heat exchanger warms up, usually within about 2 minutes. During automatic defrost, the fan may stop for 3 to 12 minutes, and it may pause briefly in Dry mode to prevent condensed water from evaporating back into the room.

Moisture on the air outlet vent

When the AC runs for a long time in high humidity, moisture may condense on the air outlet grille and drip. This is normal and does not require any action.

When to Call Godrej Service Centre for Technician Visit?

There is a harsh or abnormal sound during operation. An unusual sound during operation often signals a fan, motor, or compressor problem inside the unit. This is not something to fix on your own, so a technician should inspect it right away.
A burning or unusual odor is emitted from the unit. A burning smell usually means overheating wiring, a damaged PCB, or an electrical fault inside the AC. This is a serious warning sign, and the unit should be turned off immediately and checked by a professional.
Water is leaking inside the room continuously. Continuous water leakage can point to a blocked drain, damaged indoor unit, or an installation issue. Ignoring it can lead to fire risk or damage to the unit, so a technician visit is needed.
The air switch or circuit breaker trips frequently. Repeated tripping usually indicates an electrical fault, overload, or a wiring problem inside the AC. This should be checked by a trained technician instead of resetting the breaker repeatedly.
Water or any foreign object accidentally enters the indoor unit. If water or any foreign substance gets inside the appliance, the power supply should be cut off immediately and a service centre contacted. Continuing to use the AC in this condition can lead to electric shock or fire.
The power cord or plug becomes abnormally hot. An abnormally hot power cord or plug is a sign of loose connections or electrical damage. This is a fire hazard, and a technician should inspect and replace the cord if required.

Godrej AC error codes help you spot problems early, before they turn into bigger repairs. Start with simple steps like a power reset, filter cleaning, and airflow checks.

Avoid repeated restarts for compressor, PCB, or voltage-related codes, as this can worsen the fault. If the same error returns or the AC still malfunctions, contact Godrej service centre for professional diagnosis.
