Troubleshooting

Fujitsu General AC Troubleshooting
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:

Problem:

  • 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

Problem:

  • 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.

Symptom: Smells

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.

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.
