Fujitsu General AC Troubleshooting
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the electrical breaker and consult authorized service personnel. Merely turning off the unit’s power switch will not completely disconnect the unit from the power source. Always be sure to turn off the electrical breaker to ensure that power is completely off.
Before requesting service, perform the following checks:
Symptom: Doesn’t operate immediately:
- If the indoor unit is stopped and then immediately started again, the compressor will not operate for about 3 minutes, in order to prevent fuse blowouts.
- Whenever the electrical breaker is turned off then on again the protection circuit will operate for about 3 minutes, preventing unit operation during that period.
Symptom: Noise is heard
- During operation or immediately after stopping the unit, the sound of water fl owing in the air conditioner’s piping may be heard. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation (sound of refrigerant fl owing).
- During operation, a slight squeaking sound may be heard. This is the result of minute expansion and contraction of the front panel due to temperature changes.
- During Heating operation, a sizzling sound may be heard occasional. This sound is produced by the Automatic Defrosting operation.
Problem: Some smell may be emitted from the indoor unit. This smell is the result of room smells (furniture, tobacco, etc.) which have been taken into the indoor unit.
Symptom: Mist or steam is emitted
- During Cooling or Dry operation, a thin mist may be seen emitted from the indoor unit. This results from the sudden Cooling of room air by the cool air emitted from the indoor unit, resulting in condensation and misting.
- During Heating operation, the outdoor unit’s fan may stop, and steam may be seen rising from the unit. This is due to Automatic Defrosting operation.
Symptom: Airfl ow is weak or stops
- When Heating operation is started, fan speed is temporarily very low, to allow internal parts to warm up.
- During Heating operation, if the room temperature rises above the temperature setting, the outdoor unit will stop, and the indoor unit will operate at very low fan speed. If you wish to warm the room further, set the temperature for a higher setting.
- During Heating operation, the indoor unit will temporarily stop operation (Max.15 minutes) as the Automatic Defrosting mode operates. During Automatic Defrosting operation, the OPERATION Indicator Lamp will fl ash.
- During Dry mode, the indoor unit will operate at low speed; in order to adjust room humidity, the indoor unit’s fan may stop from time to time. Also, the fan may operate at very low speed when adjusting room humidity.
- During SUPER QUIET operation, the fan will operate at very low speed.
- In the monitor of AUTO operation, the fan will operate at very low speed.
Symptom: Water is produced from the outdoor unit
Problem: During Heating operation, water may be produced from the outdoor unit due to Automatic Defrosting operation.
Symptom: Doesn’t operate at all
- Has the circuit breaker been turn off?
- Has there been a power failure?
- Has a fuse blown out, or a circuit breaker been tripped?
- Is the intake grille completely closed?
- Is the timer operating?
Symptom: Poor Cooling (or Heating) performance
- Is the Air Filter dirty?
- Are the air conditioner’s intake grille or outlet port blocked?
- Did you adjust the room temperature settings (temperature) correctly?
- Is there a window or door open?
- In the case of Cooling operation, is a window allowing bright sunlight to enter? (Close the curtains.)
- In the case of Cooling operation, are there heating apparatus and computers inside the room, or are there too many people in the room?
- Has OUTDOOR UNIT LOW NOISE not been set?
- Is the unit set for SUPER QUIET operation?
Symptom: The unit operates differently from the Remote Controller’s setting
- Are the Remote Controller’s batteries dead?
- Are the Remote Controller’s batteries loaded properly?
If the problem persists after performing these checks, or if you notice burning smells, or the OPERATION Indicator Lamp and the TIMER Indicator Lamp flashes, and ECONOMY Indicator Lamp flashes fast. Immediately stop operation, turn off the electrical breaker and consult authorized service personnel.
