Fujitsu Air Conditioner 94 Error Code

Compressor overcurrent (trip detection). What it means, which models show it, and how to clear it, easiest fix first.

Fujitsu All Fujitsu air conditioner codes

Moderate DIY

The outdoor unit stopped after the compressor tripped on overcurrent during repeated start attempts. Fujitsu's guide points first to a dirty outdoor coil, an outdoor fan motor fault or hot discharge air recirculating back into the unit; a compressor or board problem is also possible.

Lamp pattern: on models that show faults with the indicator lamps, Fujitsu's tables for many current wall-mounted (RL/RLS/RLX, LZAH), compact ducted (RGLX) and RLF multi-zone units show this code as the Operation lamp flashing 9 times and the Timer lamp flashing 4 times, with the Economy lamp marked "continuous". Other Fujitsu units, such as universal-mount and ceiling-suspended models, use different lamps. A wired controller shows the code as a number. Shown as 94.1 on some ceiling cassette models. Fujitsu's older code set (for example older 9CQ/9RLQ/12CQ wall units, RMLQ-series multi-zone heads and some RCLX ceiling cassettes) uses different numbers for many faults, so always check the manual for your model.

Safety first: unplug the air conditioner (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Fujitsu 94

Clear around the outdoor unit
With the breaker off, remove leaves, grass clippings, snow or anything stored against the outdoor unit, and keep about 2 ft (60 cm) clear on all sides so warm air can't loop back in. Brush loose debris off the outside of the coil fins by hand or with a soft brush; do not use a pressure washer or bend the fins.
Look at the outdoor fan
With the breaker still off, look through the grille for sticks, leaves or ice touching the fan blade. Clear debris from the outside of the grille only; don't put your hand or tools through it or remove it.
Reset the power at the breaker
Switch the system off with the remote, then turn off its circuit breaker in your home's main panel. Wait about 5 minutes, switch the breaker back on and restart the unit. If the code returns within a few minutes, write it down for the technician.

When to call a technician

If the coil and fan are clear and the code returns, call an HVAC technician to check the fan motor, compressor and inverter.
