  1. Check fuse or circuit breaker in switchboard marked A/C - switch off and back on again - retry unit.
  2. Check batteries in the remote control - is the machine beeping you when you operate the control?
  3. Check the main switch inside the unit's front cover - is it on?
  4. Try the emergency switch located inside the front cover.
  5. Ensure the outdoor unit is not covered - it must have a free passage of air through it.
  6. Check that the remote control is set for either heat or cool and the set temperature is above or below the room (ambient) temperature. N.B. If unit is set to 'dry' it will not cool in extreme temperatures.
  7. Remember that the unit incorporates an automatic time delay before starting.
  8. Is the unit in defrost mode? If so, leave the unit on and it will automatically return to heating mode. N.B. In defrost mode water vapour is emitted from the outdoor unit.
  9. Read the instruction book.

  1. 'P8' (Mitsubishi Electric) or 'spanner' symbol (Daikin) showing on the controller and flashing light:
    a) simply switch off the power to the air conditioning in the meter box and switch it back on again. Don't forget to remove switch locking wire (if fitted).
    b) Retry system. This fault usually occurs if there has been a local power failure. Sometimes it may be necessary to allow time for the power supply to be rectified. If problem persists then call us on 9831 3700.
  2. If system is operating but not efficiently - check return air filter behind air intake grill in ceiling is clear - ALL air must pass through here before supplying outlets.
  3. Check that the zone or zones that are switched on allow air to return to the air intake filter - close off areas that are not being air conditioned, that is, toilets, bathrooms, outside doors and windows.
  4. Check that the selected temperature is above or below ambient temperature and that 'cool' or 'heat' is selected. Not 'fan' and not 'dry'.
  5. Is the outdoor machine running? Remember to allow a five minute delay.
  6. Make sure that nothing is obstructing air flow through the outdoor machine.
  7. If fuses in the meter box are of the cartridge type, you cannot check them without a meter - you must change all three.
