This diagnostic checklist is a useful reference to keep in case of trouble with your air conditioner. We find over 80% of problems can be solved having read through this page.
If your system is not working as you think it should we can arrange for a technician to visit and perform a diagnostic check.
Currently a diagnostic call out costs $249*, for the call out & up to an hour of our technicians time; if we can fix the problem in that time we will, if not we will quote you to repair, replace, or both. If your system is covered by warranty then you will not be charged; however please be aware of what is and isn’t covered by warranty, by checking Daikin’s warranty card and our Terms and Conditions
However, before booking a technicians visit it is worth running through our diagnostic checklist – it could save you a call out fee and a wait.
The system does not seem to be cooling/heating enough. Check the following…
- The air filters are clean.
- The mode settings, making sure you have the correct setting for the season.
E.g. Heating or Cooling
SUN Symbol is for Heating
SNOWFLAKE symbol for Cooling
These settings are controlled by your MODE button.
- There is nothing blocking the air inlet or outlet of the indoor and outdoor units.
- The temperature setting is appropriate.
- All windows and doors are closed.
- The air flow rate and air direction is set appropriately.
The system is not responding to the remote…
- Check the batteries – to change the batteries, slide the remote panel unit it stops, then give it an extra tug to slide the panel completely off the remote. The batteries should now be exposed.
The system seems to be struggling and making a noise…
- Have the filters been cleaned recently? Filters need to be cleaned a minimum of every six months. Alternatively for a thorough clean of your system contact Peninsula Air Conditioning to arrange for a technician to carry out a General Service (recommended on a yearly basis). Find out what we do on a General Service.
- In cold weather wait 5 minutes as the system warms itself up before going into working mode; this is for system protection. If after 5 minutes still nothing happens switch the system off from the mains power source, either at the fuse box or isolator switch, and leave off for 20 minutes before turning back on and trying again.
The Outdoor unit emits water or steam…
- In heat mode – the frost of the outdoor unit melts into water or produces steam when the system is in defrost mode.
- In Cool or Dry mode – moisture in the air condenses into water on the cool surface of the system.
- We suggest a tray to be placed under the outdoor unit, alternatively a drain kit can be added at an additional cost.
The indoor unit gives out an odour…
- This happens when the smells of the room, furniture or cigarettes are absorbed into the unit and discharged with air flow. If this happens we recommend our technician carries out a General Service on your system to try and eliminate the smells.
The outdoor fan rotates while the air conditioning system is not in operation…
- After operation is stopped: The outdoor fan continues rotating for another 30 seconds for system protection. While the air conditioning is not in operation: When the outdoor temperature is very high, the outdoor fan starts rotating for system protection.
An abnormal function happens during operation…
- The air conditioner may malfunction with lightning or radio waves. Turn off power at source, leave for about 20 minutes, and turn back ON again and try operating the air conditioner with the remote controller.
The system has a fault code…
- Take a note of the fault code and contact Peninsula Air Conditioning to book a technician to assess; we may ask you to reset your system from the mains power source first.
The system is not working at all or not working as it should…
- If there has been a power surge your system may stop working correctly; try switching the power off at the mains power source, either at the fuse box or at the isolator, for at least 20 minutes.
If you are still having problems, then please contact us and will endeavour to help, or put you on our service schedule for a technician to assess your problem as soon as possible. If your system has been working okay but it’s a while since it’s been looked at, a General Service is probably a good idea.
