What Does Error 33 Mean?
The Fujitsu General Air Conditioner error 33 indicates a communication failure between the indoor and outdoor units, primarily due to an indoor fan motor electricity consumption detection error. This often results in the indoor fan not spinning or spinning inconsistently, leading to weak or absent airflow despite the compressor running. It may suggest issues with the indoor fan motor, wiring, or power supply to the motor, requiring careful inspection and potential repair.
Common Symptoms:
- Unit stops operation and displays error 33
- Indoor fan does not spin or spins inconsistently
- Airflow is weak or absent despite compressor running
Possible Causes
- Indoor fan motor current/voltage anomaly (motor load out of range) (medium)
How to Fix Error 33
DIY Fix Basic Checks for Indoor Fan Issues
- Turn off the unit and power at the breaker.
- Check that the indoor fan is free of obstructions (e.g., dust, debris).
- Ensure the airflow path (filters, intake grille) is clean and not blocked.
- Restore power and see if the error clears; if not, proceed to technician actions.
Technician Only Electrical and Motor Inspection
- Disconnect power and access the indoor unit’s fan motor and wiring harness.
- Check for loose, corroded, or damaged connections to the fan motor.
- Measure motor voltage and current to verify against manufacturer specs.
- Replace indoor fan motor if it draws excessive current or shows electrical/mechanical fault.
- After repairs, reset error memory and test run the unit.
Parts needed: Indoor fan motor, Control wiring connectors, Possibly indoor unit PCB if it falsely detects current error
- If the fan does not turn freely after obstruction removal
- If error persists after basic cleaning and reset
- If unusual noise or vibration from indoor fan motor is present
