Also shown as

Lamp pattern: on models that show faults with the indicator lamps, Fujitsu's tables for many current wall-mounted (RL/RLS/RLX, LZAH) and compact ducted (RGLX) units show this code as the Operation lamp flashing 6 times and the Timer lamp flashing 5 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 65.3 on some ceiling cassette models. Code 64 is a related fault in the PFC (active filter) power circuit. 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.

Difficulty

Try the basic checks, but the usual fix is a technician's job.

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 65

  1. 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. 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. Poor airflow through the outdoor coil is one of the things Fujitsu's guide says to rule out.

  2. 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 code returns, a technician needs to check the compressor, fan and power circuit.
