9RLS3H Halcyon Repair Guide

Common symptoms

• Timer light flashing
• Reduced cooling
• Ice on outdoor coil in heat mode

Troubleshooting steps

1. 1
   Count timer-light flashes

   Fujitsu fault codes are flash-count based. 3 flashes = indoor sensor; 5 = outdoor sensor.

2. 2
   Clean indoor filter + coil

   Halcyon indoor coil clogs with dust in desert homes — pull cover, spray coil cleaner.

3. 3
   Verify defrost cycle

   Ice = defrost sensor failure or low refrigerant. Confirm with subcooling reading.
