Gree Split AC Error Code FC — What It Means & How to Fix It

What Does This Error Mean?

FC means both the compressor and the outdoor fan motor have malfunctioned simultaneously. This is a critical fault pointing to a serious electrical or PCB failure in the outdoor unit. Do not try to restart — call a technician immediately.

Affected Models

Gree FAIRY Series
Gree LOMO Series
Gree U-MATCH Series
Gree PULAR Series
Gree Inverter Split System

Common Causes

Outdoor PCB failure stopping drive signals to both the compressor and fan motor
Power supply fault at the outdoor unit cutting power to both components
Major electrical fault such as a blown fuse or tripped protection within the outdoor unit
Lightning or power surge damage to the outdoor unit electronics
Both the compressor and fan motor coincidentally failing at the same time

How to Fix It

Switch the AC off at the thermostat and at the circuit breaker immediately.

FC indicates a major fault in the outdoor unit. Continuing to send power to it risks further electrical damage.
Check whether the outdoor unit has any visible damage — scorch marks, burning smell, or signs of water ingress.

These signs help narrow down the cause before the technician arrives. Share your observations when you call.
Check the circuit breaker for the outdoor unit. If it has tripped, reset it once.

A tripped breaker after a power surge may be the only issue. If it trips again immediately on reset, there is an active fault.
Do not attempt to restart the AC if the circuit breaker has tripped more than once.

Repeated tripping means the circuit protection is doing its job — there is a real fault drawing excess current.
Call a qualified Gree technician and describe the FC code and any observations about the outdoor unit.

FC diagnosis typically requires testing each outdoor component individually. This takes 1–2 hours for a thorough check.

When to Call a Professional

FC is always a job for a qualified technician — do not attempt to diagnose or repair the outdoor unit yourself. The outdoor unit contains capacitors with lethal charge even after power is removed. A technician needs to test the PCB, power supply, compressor, and fan motor separately.

Frequently Asked Questions

Is FC ever caused by something simple like a tripped fuse?

Yes — sometimes a blown fuse inside the outdoor unit kills power to multiple components at once, causing FC. A technician will check the fuses first as it is the quickest and cheapest fix to rule out. However, finding why the fuse blew is equally important.

Can a power surge cause FC?

Yes — a lightning strike nearby or a severe power surge can destroy the outdoor PCB, causing both components to stop responding. This is one of the more common causes of FC in areas with unstable power supply. A surge-protected isolator switch helps prevent this.

How expensive is an FC repair?

FC repair cost varies widely depending on the root cause. A blown fuse is cheap; an outdoor PCB replacement costs several hundred dollars; a compressor replacement can approach the cost of a new unit. Get a diagnosis from a technician before deciding on repair versus replacement.
