In brief
Gree E5 is an overcurrent protection on several documented ranges. It does not by itself establish low supply voltage or a failed compressor. Record the exact model and have a qualified engineer compare electrical measurements with that model’s service manual.
The Gree service manuals consulted list E5 as overcurrent protection, with model-dependent limits.

What does fault code E5 on Gree mean?
On several documented Gree ranges, E5 is an overcurrent protection. The applicable threshold and checks depend on the model. E5 alone does not prove a compressor fault.
Power supply, wiring or compressor load may trigger the protection; the exact cause requires model-specific diagnosis.
Symptoms
- Intermittent operation
- House lights dim when the air-con starts
Safety notice
Do not open the units or measure voltage or current without electrical qualification.
Diagnosis
1. Identify the model
- Record the complete indoor and outdoor references and any other displayed codes.
- Check the E5 table in the manual for those exact references.
2. Request a qualified electrical check
- Have a qualified engineer check supply, wiring and current against the model-specific limits.
- Replace a component only after confirming the cause.
Repair and return to service — Gree fault E5
A qualified engineer compares measurements with the limits in the exact model manual and repairs the confirmed cause.
When should you call an F-Gas engineer?
If E5 appears or returns after switching the unit off.
Affected models
- Multi21 Plus (30k/36k/42k)
- Sapphire (18MBH/24MBH)
- High Static Slim Duct
- Multi Plus Ultra
- Livo Plus (30k/36k 230V)
- All Match Floor Ceiling R32 (9k/24k)
Field context
This code appears when the system detects excessive current draw, causing a safety shutdown of the compressor and outdoor fan. It often manifests as a specific flashing of indicator lights and a total stop of cooling or heating production depending on the mode.
Frequently asked questions
Does E5 mean the compressor is faulty?
Not necessarily. E5 is an overcurrent protection on supported ranges; the underlying cause needs model-specific checks.
