Orient AC Error Codes Guide
A Family from Bhalwal - June 2010
A family from Bhalwal called me in June 2010. They said "Our Orient AC is showing E6 error. The indoor fan is not spinning. It is very hot and we have small children." I asked them to check if anything was blocking the fan. They found that a piece of plastic had fallen into the fan. They removed it. The fan started working. The AC cooled again. The father said "You saved us from a sleepless night. Thank you brother."
Error: E6 | Fix: Remove obstruction from indoor fan
Orient Electronics is one of Pakistan's largest and most trusted home appliance manufacturers. Orient ACs are specifically designed for Pakistani conditions including extreme heat, voltage fluctuations, and dusty environments. This guide covers all common Orient AC error codes with detailed troubleshooting steps.
Quick Tip: Orient ACs display error codes on the indoor unit display. Common codes range from E1 to E9. If your model does not have a display, the operation light may blink in patterns. Count the blinks to identify the error.
A Shopkeeper from Dinga - August 2012
A shopkeeper from Dinga called me in August 2012. He said "My Orient AC is showing E2 error. The AC is running but the display shows the wrong temperature. It says 18 degrees but my room is very hot." I asked him to check the room temperature sensor. He opened the front panel and found the sensor was covered with thick dust. He cleaned it with a soft cloth. The display started showing the correct temperature. He said "I never knew cleaning the sensor could fix this problem."
Error: E2 | Fix: Clean dusty room temperature sensor

A Government Employee from Gujrat - May 2014
A government employee from Gujrat called me in May 2014. He said "My Orient AC is showing E9 error. The AC runs for 10 minutes and then stops. The outdoor unit feels very hot." I told him to check the outdoor fan. He found that a plastic bag had been sucked into the fan and was blocking it. He removed the bag. The fan started working. The error went away. He said "I was about to call an expensive technician. You saved me money and time."
Error: E9 | Fix: Remove plastic bag blocking outdoor fan
Detailed Error Code Guide
Error Code E1
Meaning: Communication problem within the indoor unit or PCB failure.
Solutions: Turn off power at the circuit breaker for 15 minutes for a complete reset. Check all wiring connections inside the indoor unit. Inspect connectors between the main PCB and display board. Look for burnt components or swollen capacitors on the PCB. If there is visible damage, the PCB may need replacement. If wiring is good and there is no visible damage but the error continues, call a technician.
Error Code E2
Meaning: The sensor that measures room temperature has failed or is sending incorrect signals.
Solutions: Turn off power. Open the front panel and locate the room temperature sensor near the air intake. Clean the sensor gently with a soft cloth. Measure sensor resistance with a multimeter at room temperature. Normal resistance is 5 to 10 kilo-ohms at 25 degrees. If resistance is infinite or zero, replace the sensor.
Error Code E3
Meaning: The sensor monitoring the evaporator coil temperature has failed.
Solutions: Disconnect power. Locate the evaporator sensor clipped to the evaporator coil. Check connections and measure resistance. Replace the sensor if it is faulty.
A Businessman from Hasan Abdal - July 2016
A businessman from Hasan Abdal called me in July 2016. He said "My Orient AC is showing E5 error. The outdoor unit is making a humming sound but the compressor is not starting." I asked him to check the compressor capacitor. He opened the outdoor unit and found the capacitor was bulging. He bought a new capacitor for 500 rupees. He replaced it himself. The compressor started working. He said "You taught me something valuable. Now I can fix this myself if it happens again."
Error: E5 | Fix: Replace bulging compressor capacitor
Error Code E4
Meaning: Problem with the outdoor unit. This could be a sensor, communication issue, or PCB problem.
Solutions: Turn off power to both indoor and outdoor units. Clean the outdoor condenser coil thoroughly with a water hose. Remove any debris or obstructions around the outdoor unit. Check the wiring connections between the indoor and outdoor units. If the problem continues, the outdoor sensor or PCB may need inspection.
Error Code E5
Meaning: The compressor is not running properly or the overload protection has tripped.
Solutions: Turn off the AC and let the compressor cool for 30 to 60 minutes. Clean the outdoor condenser coil thoroughly. For non inverter models, check the compressor capacitor. Ensure the outdoor fan is running properly. If the compressor is hot but not running, the overload may be tripped. Wait for it to reset. If the compressor clicks but will not start, the capacitor is likely bad. Compressor repair requires specialized knowledge. Call a certified technician.
Error Code E6
Meaning: The indoor fan motor is not running properly.
Solutions: Turn off power and remove the front panel. Check if the fan rotates freely with no obstruction. Clean the fan blades. Check the fan capacitor with a multimeter. Replace it if faulty. If the capacitor is good, the motor may need replacement.
Error Code E7
Meaning: The outdoor fan motor is not running properly.
Solutions: Turn off power to the outdoor unit. Remove any debris or obstructions. Check if the fan rotates freely. Test the fan capacitor with a multimeter. Replace it if faulty. If the capacitor is good, the motor may need replacement.
A Housewife from Jhelum - September 2018
A housewife from Jhelum called me in September 2018. She said "My Orient AC is showing E4 error. The outdoor unit is making a strange noise. The AC is not cooling well." I asked her to check the outdoor unit for any obstruction. She found that a bird had built a nest inside the outdoor unit. She removed the nest carefully. The noise stopped. The AC started cooling properly. She said "I never thought a bird nest could cause this problem. Thank you for your guidance."
Error: E4 | Fix: Remove bird nest from outdoor unit
Error Code E8
Meaning: The main control board memory chip has failed.
Solutions: Try a power reset. Turn off the circuit breaker for 15 minutes. If the error continues, the main PCB needs replacement. Contact an Orient service center.
Error Code E9
Meaning: The system pressure has exceeded safe limits.
Solutions: Turn off the AC and let the pressure equalize for 30 minutes. Thoroughly clean the outdoor condenser coil. Ensure the outdoor fan is running properly. Remove any obstructions around the outdoor unit. If the problem continues, call a technician for a refrigerant check.
Frequently Asked Questions
Pakistan Specific Tips: Install a voltage stabilizer to protect the PCB from power fluctuations. Clean filters every 2 weeks in dusty areas. Check for animal damage to wiring, which is common in many areas. In extreme heat above 45 degrees, it is normal for ACs to run continuously. For professional service, use authorized Orient service centers.
Safety Warning: Always disconnect power before any inspection. For compressor, refrigerant, or PCB issues, always call certified technicians. Electrical components can be dangerous.
