Fujitsu Mini-Split Code 97

Soft lockoutShown as: OPERATION lamp blinks 9 times, TIMER lamp blinks 7 times, ECONOMY lamp blinking continuously

Outdoor unit fan motor error. The outdoor fan turned slower than 100 RPM within 20 seconds of starting; after three repeats inside 60 seconds the compressor and fan both stop.

Manual wording: “Outdoor Unit Fan Motor Error - When outdoor fan motor rotation speed is less than 100 RPMs in 20 seconds after fan motor starts, fan motor stops.”

Documented for: RL2, RLS2, RLS3, RLB/RLXB, RLF, RLF1, RGLX, RLE, LUAS1, LMAS, LZBS, LZAS, LPAS series

Likely causes, most common first

  1. Outdoor fan blade obstructed, iced, or the motor is locked
  2. Excessive ambient temperature around the fan motor from nearby heat-producing equipment
  3. Outdoor fan motor windings out of specification, or missing DC supply to the motor
  4. Failed outdoor main PCB

What you can safely check yourself

  • With the power off at the disconnect, look for leaves, ice, or debris jamming the outdoor fan blade
  • Clear snow and ice buildup from around and on top of the outdoor unit
  • Turn the power off at the disconnect for about 5 minutes, then restore power

When to call a technician

Fujitsu's next steps are ohming the fan motor windings and checking DC voltage to the motor. That means a licensed technician.

A Fujitsu mini-split throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
