Fujitsu Mini-Split Code 94
Soft lockoutShown as: OPERATION lamp blinks 9 times, TIMER lamp blinks 4 times, ECONOMY lamp blinking continuously
Over current error (trip detection). The compressor tripped on overcurrent immediately after starting, ten times consecutively, so the unit shut down.
Manual wording: “Over Current Error - Protection stop by overcurrent generation after inverter compressor start processing completed generated consecutively 10 times.”
Documented for: RL2, RLS2, RLS3, RLB/RLXB, RLF, RLF1, RGLX, RLE, LUAS1, LMAS, LZBS, LZAS, LPAS series
Likely causes, most common first
- Clogged outdoor heat exchanger restricting airflow
- Defective condenser fan motor
- Discharged air being pulled back into the outdoor unit (short cycling of air)
- Compressor or inverter fault
What you can safely check yourself
- Check the outdoor coil for heavy dirt, cottonwood, grass clippings, or leaves and clear away anything blocking it
- Make sure the outdoor unit has clearance on all sides and its discharge air is not blowing into a wall or fence and back into the coil
- Turn the power off at the disconnect for about 5 minutes, then restore power
When to call a technician
If airflow is clear and the code returns, the condenser fan motor or the compressor circuit has to be tested by a licensed technician.
A Fujitsu mini-split throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
