Gree AC Error Codes Guide
A Family from Rahim Yar Khan - July 2017
A family from Rahim Yar Khan called me in July 2017. The temperature was 47 degrees. Their Gree AC was showing E1 error. The outdoor fan was running but the compressor was not cooling properly. I asked them to check the outdoor condenser coil. It was completely covered in cotton from nearby trees. They cleaned the coil with a water hose. After 30 minutes, they restarted the AC. The error was gone. The father said "My children were suffering in the heat. You saved us."
Error: E1 | Fix: Clean outdoor condenser coil
Gree is one of the world's largest air conditioner manufacturers. Gree ACs are very popular in Pakistan because they handle high temperatures well. This guide covers all common Gree AC error codes with real solutions for Pakistani conditions.
Quick Tip: Gree ACs have a self diagnostic system. When an error occurs, the display shows the code or the operation light blinks in patterns. Count the blinks to identify the error code before resetting.
A Shop Owner from Mirpur Khas - May 2021
A shop owner from Mirpur Khas contacted me in May 2021. He said "My Gree AC is showing E5 error. The AC turns on but there is no cooling. The outdoor unit is not responding." I asked him about the wiring between indoor and outdoor units. He checked and found that rats had eaten the communication wire. He fixed the wire connection. The error went away. He said "I learned something valuable today. Now I will protect my wires with metal pipe."
Error: E5 | Fix: Repair damaged communication wire

E2 | Anti-freeze protection | Clean filters, thaw unit | Easy |
E3 | Low pressure | Call technician for refrigerant | Hard |
E4 | Compressor discharge | Check refrigerant, clean coils | Hard |
E5 | Communication error | Check wiring, reset power | Medium |
E6 | Indoor fan motor | Check fan capacitor | Medium |
E7 | Outdoor fan motor | Check fan, capacitor | Medium |
F1 | Room sensor | Replace sensor | Easy |
F2 | Evaporator sensor | Replace sensor | Easy |
A Doctor from Abbottabad - August 2023
A doctor from Abbottabad called me in August 2023. He said "My Gree inverter AC is showing E2 error. There is ice on the indoor unit. The AC is not cooling." I told him to turn off the AC and clean the air filters. He opened the front panel and found the filters were completely black. He cleaned them and let the ice melt for 4 hours. After restarting, the AC worked perfectly. He said "I am a doctor but I did not know about this. Thank you for teaching me."
Error: E2 | Fix: Clean air filters and thaw ice
Detailed Error Code Guide
Error Code E1
Meaning: The system has detected abnormal pressure in the refrigeration cycle.
Common causes in Pakistan: Dirty condenser coil, outdoor fan not running, blocked airflow, extreme temperatures above 48 degrees.
Solutions: Turn off AC for 30 minutes. Clean outdoor condenser coil with water. Remove debris around outdoor unit. Ensure outdoor fan runs. If problem continues, call technician for refrigerant check.
Error Code E2
Meaning: The evaporator coil is too cold and may freeze.
Solutions: Turn off AC and let it thaw for 2 to 3 hours. Remove and clean air filters. In dusty cities, clean filters every 2 weeks. Ensure indoor fan is running. If error returns, refrigerant may be low. Call technician.
Warning: Never run AC with ice on coils. It can damage the compressor.
Error Code E3
Meaning: Refrigerant pressure is too low, usually indicating a leak.
Solutions: Look for oil stains on copper pipes (sign of leak). Listen for hissing sounds. This error almost always requires a professional. Call a certified technician for leak detection and repair.
Professional Only: Refrigerant work requires certification. Do not attempt DIY.
A Factory Owner from Sheikhupura - June 2019
A factory owner from Sheikhupura called me in June 2019. He said "My Gree AC is showing E6 error. The indoor fan is not spinning. It is very hot in my office." I guided him to check the fan capacitor. He had a multimeter. The capacitor reading was zero. He bought a new capacitor for 350 rupees. He replaced it himself. The fan started working. He said "You saved me from buying a new AC. I will recommend your service to everyone."
Error: E6 | Fix: Replace indoor fan capacitor
Error Code E4
Meaning: Compressor discharge temperature is too high.
Solutions: Turn off AC and let compressor cool for 30 to 60 minutes. Clean outdoor condenser coil. Ensure outdoor fan is running. If error continues, refrigerant may be low. Call technician.
Error Code E5
Meaning: Indoor and outdoor units cannot communicate.
Solutions: Turn off both units at circuit breaker for 15 minutes. Check all wiring connections. Look for rodent damage to communication cable. Ensure connections are tight. If wiring is good, one of the PCBs may need replacement. Install a voltage stabilizer for protection.
Error Code E6
Solutions: Turn off power and remove front panel. Check if fan rotates freely. Clean fan blades. Check fan capacitor with multimeter. Replace if faulty. Test fan motor windings for continuity. Replace faulty capacitor or motor as needed.
Error Code E7
Solutions: Turn off power to outdoor unit. Remove debris around fan. Check if fan rotates freely. Inspect fan capacitor for bulging or damage. Test capacitor with multimeter. Replace if faulty. If capacitor is good, motor may need replacement.
A Hotel Owner from Murree - December 2025
In December 2025, a hotel owner from Murree called me. He said "My Gree AC is showing E1 error in heating mode. The outdoor unit is making noise." I asked him to check the outdoor coil. He found ice buildup on the outdoor unit. I told him to run the AC in cooling mode for 15 minutes to defrost. He did that. The error went away. He said "You saved my guests from a cold night. Thank you."
Error: E1 | Fix: Defrost outdoor unit
Error Code F1
Solutions: Locate sensor behind front panel near air intake. Check connections. Measure resistance at room temperature. Normal reading is 5 to 10 kilo-ohms. Replace sensor if readings are out of range.
Error Code F2
Solutions: Locate sensor clipped to evaporator coil. Check connections. Measure resistance. Replace sensor if faulty.
Frequently Asked Questions
Pakistan Specific Tips: Install a voltage stabilizer to protect the PCB. Clean filters every 2 weeks in dusty areas. In extreme heat above 45 degrees, it is normal for ACs to run continuously. Check for rodent damage to wiring, which is very common in Pakistani homes.
Safety Warning: Always disconnect power before any inspection. For compressor, refrigerant, or PCB issues, always call certified technicians. Electrical components can be dangerous.
