LE
Gree Split AC
Severity: CriticalWhat Does This Error Mean?
LE is a critical error — the compressor drew a dangerous current spike far above normal. This can happen when the compressor seizes, a winding shorts, or voltage goes severely abnormal. Do not restart the unit — get a technician.
Affected Models
- Gree FAIRY Series
- Gree LOMO Series
- Gree U-MATCH Series
- Gree PULAR Series
- Gree Inverter Split System
Common Causes
- Compressor rotor has mechanically seized (locked rotor)
- Short circuit in the compressor motor windings
- Mains supply voltage severely abnormal — very high or very low
- Liquid refrigerant flooded back into the compressor at startup
- Compressor drive board (IPM) fault causing incorrect drive signal
How to Fix It
-
Turn off the AC at the remote and immediately switch off the outdoor unit circuit breaker.
This protects the drive board (IPM) from further damage caused by the overcurrent event.
-
Do not attempt to restart the unit, even after a waiting period.
Unlike a simple temperature protection, LE indicates a potentially catastrophic electrical event inside the compressor.
-
Check your home supply voltage if you suspect a grid voltage issue.
A voltage meter at your meter box can confirm if the supply is abnormally high or low. If so, contact your electricity provider.
-
Call a Gree-certified technician and describe the LE code.
The technician will test the compressor winding resistance, refrigerant charge, and drive board before advising on repair options.
-
Ask the technician about compressor replacement if the unit is out of warranty.
If the compressor windings are shorted, full compressor replacement is usually the only fix.
When to Call a Professional
This is a critical fault requiring immediate professional attention. Do not attempt to restart the unit — a seized compressor or shorted winding is a fire and electrical hazard. A technician must perform full electrical testing before any restart is attempted.
Frequently Asked Questions
What causes a Gree LE error code?
The most common cause is a compressor that has mechanically seized or has shorted motor windings. Severely abnormal mains voltage can also trigger it. It is one of the most serious AC error codes.
Can I reset a Gree LE error by cutting the power?
You can cut power to stop the unit, but do not treat it as a reset and restart. The underlying fault that caused the current spike is still present. Restarting risks a fire, a tripped main breaker, or further compressor damage.
Is it worth repairing a Gree AC with an LE error?
It depends on the cause and the age of the unit. If the drive board triggered a false LE due to a board fault, the repair is relatively inexpensive. If the compressor itself has seized or shorted, repair cost may approach the cost of a new unit.
