Indoor unit displays E8 and the unit stops; may be accompanied by very low airflow or ice on the indoor coil.

Safety first: Turn off the unit and allow any ice on the coil to melt before working on it. Place towels under the unit to catch drips.

• Step 1 – Clean filters:
  • Open the front panel and remove the air filters.
  • Wash with mild soap and water, rinse thoroughly, and dry completely before reinstalling.
• Step 2 – Check airflow:
  • Ensure that curtains, furniture, or covers are not blocking the indoor unit intake or outlet.
  • Verify that the louvers are open and not stuck.
• Step 3 – Inspect indoor coil:
  • With filters removed, look at the evaporator coil for heavy dust buildup.
  • If dirty, use a soft brush or a coil cleaner approved for split ACs, following the product instructions.
• Step 4 – Check fan operation:
  • Run the unit in FAN mode only and confirm strong airflow.
  • If airflow is weak, the fan motor or capacitor (on non-DC models) may be failing and should be checked.
• Step 5 – Call a technician if E8 persists: Persistent freezing after cleaning suggests low refrigerant or a sensor/control issue. A certified technician must check pressures, leak-test, and recharge if necessary.
