Daikin Air Conditioning Troubleshooting Guide: The 6 Most Common Causes Of Breakdown

What, whether will be like

Air conditioning is a very important aspect of our place of work and also our homes. It is an aspect that should not be taken lightly because it affects our health and well-being.

That’s why we’ve put together this guide to help you cut through the noise and decide whether it’s a DIY situation or a more pressing issue.

Main Causes Behind a Daikin Air Conditioning Breakdown

The most common issues of Daikin breakdowns are almost the same as every other air conditioner since they are all being used in the same way and under similar conditions.

Though all of the problems we’ll address are simplified in the list above, some may be harder to detect or understand than others. The following are some of the basic issues causing Daikin and other air conditioning systems to break down:

What Causes Water to Leak from Your Air Conditioning Unit?

If your system is leaking water, there might be a hole or a crack in the drain pan which controls the overflow of water in the system.

A blocked air filter may also be the cause of the leakage. By being clogged with dirt, the filter doesn’t allow sufficient airflow hence condensation occurs, and the system begins to leak. A crack or a hole in the drain pan can at times be seen by simply using a flashlight, although not always so easily identified.

The clogged air filters can be diagnosed by visually checking them and also testing the airflow to see how efficiently air is being produced through them.

What Causes Nasty Odours to Be Produced Air Conditioning Systems?

A smelly air conditioner can be a serious cause of discomfort in your working environment and home. Bacteria build up within your air conditioning system can be responsible for the bad odour.

To stop this from happening we need to clean our air conditioning system more regularly and also use coil cleaners and filter deodorisers which chemically clean your unit.

The office environment would also need to be maintained in a condition that inhibits the spread of bacteria and other germs.

Why Won’t My Air Conditioner Start At All?

When your air conditioner won’t start, or if the unit stops unexpectedly between cooling, it more than likely means that it is having a mechanical problem.

The best thing to do in such an instance is to get a professional service technician to look at the issue. The technician will provide a full assessment and if the system is damaged beyond restoration he can provide you with advice on a replacement.

Mechanical breakdowns are often brought about by the lack of regular maintenance of the air conditioning system. The air conditioner should be assessed once or twice a year to check if it is in good condition and to prevent minor issues before they turn into major repairs.

A Blown Fuse and Dirty Air Filters: The Air Conditioner's Worst Enemy

Dirty air filters are one of the most common causes of air conditioning malfunction.

The air filters should be changed regularly as advised by the manufacturer of your system. Failing to do this will result in the air conditioner working slowly, using more energy and eventually freezing and failing to function or failing to start at all.

A blown fuse is another issue that can cause the air conditioner to break down. The fuse protects the motor and the compressor. If the fuse blows there might be bigger problems underlying your air conditioning system, which can be traced to its installation or a fluctuating amount of power from the power source.

Daikin Air Conditioning Troubleshooting Manual: 6 Simple Solutions for the Most Common Issue

Now that you’ve read up on some of the most common causes for AC breakdown, here are some simple solutions that may help rectify these issues.

How to Fix a Daikin Air Conditioner that Doesn’t Start

These can be brought about by a blown fuse, hence there is no completion of the circuit causing it to not start. It can be solved by replacing the fuse. Also, the power source could be the root cause. If the fuse is working well, make sure to check and test your power source for glitches.

How to Fix a Leaking Daikin Air Conditioner

Air conditioner leakage originates from the destroyed drainage pan. It might be cracks or holes in the drain pan. To remedy these, you will need to replace the drain pan. And also keep the air conditioner clean from dirt since that is the root cause of the issue causing the overflow to the drain pan.

What if My Daikin Air conditioning unit has a Refrigerant Leak?

Leakages from the refrigerant can be brought about by vibration during usage of the system as well as a knock or a bump to the system and its piping. To evade such occurrences, when installed, your system should be mounted and well-grounded.

A refrigerant leak can be extremely detrimental to health, so if you suspect that the refrigerant is leaking you should call an AC expert for repair or replacement ASAP.

How to Fix a Daikin Air Conditioner That Won’t Turn Off

If the air conditioner fails to turn off, the wiring aspect of the system could be the problem. A qualified technician can check your wiring and correct the problem. If you notice these problems, be quick to call a professional and don’t switch it on until the problem is resolved, because you might be exposed to electrical shocks from the not well-functioning air conditioning system.

How to Fix a Daikin Air Conditioner that Isn’t Heating or Cooling Properly

This problem might arise from a thermostat which is not working well. It might also happen as a result of a frozen coil which is responsible for evaporation. Evaporation is vital for cooling and if this coil is frozen a service technician will be able to get it working.

How to Fix a Daikin Air Conditioner that Produces Weird or Unusual Smells

A smelly air conditioner will almost always be attributed to clogged or dirty air filters. This also reduces the efficiency of your air conditioning system, often resulting in more energy consumption and significantly higher energy bills.

To stop this from happening we need to clean our air conditioning system more regularly; use coil cleaners and filter deodorisers which chemically clean your unit.

How to Fix a Daikin Air Conditioner that Makes Strange or Loud Noises

Noise from the air conditioning system results from a clogged air filter which causes the system to experience hardship while doing its function. And you know if the air is having difficulty leaving one area through a small hole it will produce some sound. To avoid this, clean the system regularly and also replaces your air filter regularly.

My Problem isn't Listed Above, What Should I Do?

If your problem hasn’t been covered by our troubleshooting guide, chances are it is a more serious problem with a technical aspect of your air conditioner.

In these cases, you should get a professional Alliance service technician to act on the problems before they develop into major issues which would evidently cost a lot more money to fix and at times cannot be resolved.

Ideally, it is better to get the team to work on your air conditioner and service it regularly in order to prevent major breakdowns. At Alliance, our HVAC family is equipped with highly qualified experts in air conditioning repair. If you’ve noticed a problem with your AC unit, give us a call and we’ll drive out to anywhere in NSW for a free quote anytime.

How Do I Know If My Air Conditioner Can Be Fixed?

Although we always encourage our customers to stick with the most effective solution within their budget, there are times when repairing the AC unit may not be the most cost-effective option. In some cases (especially when the air conditioning system is significantly outdated), the parts required to fix the system may end up costing you a fortune.

Our friendly Alliance technicians will always provide tailored recommendations for your specific AC model and provide you with transparent pricing that weighs up the pros and cons of repair. Usually in these cases, however, it can be far more beneficial to opt for air conditioner replacement over repair.
