Air Conditioning Repair: Thermostat Problems

Your air conditioning unit is essential during the summer months and yet, it is also something that most of the 4.6 million Australians with air conditioning take for granted. That is until something goes wrong with it. 

Fortunately, a quick call to the experts dealing with air conditioning in Sydney should have you up and running in no time.

But, that doesn’t mean you shouldn’t have a basic understanding of the most common thermostat related issues. Here’s a quick guide to everything you need to know:

Power Outage

If there is no power to the thermostat it can’t tell your air conditioning unit to switch on, off, or operate in any other manner. 

When your air conditioning suddenly stops working you need to verify that the thermostat is in the right position and has power. If it doesn’t check the breaker; if this is okay turn it off and inspect the wiring inside your thermostat.

You may find a buildup of soot, dirt, or other debris. This can prevent the thermostat from working properly; clean it with a soft brush to get rid of this debris. It’s also worth checking that all the wiring is secured properly and there is no visible damage if there is your thermostat may be shorting out and the wiring needs to be fixed before you use it again.

Faulty wiring can cause fires.

Location Of Thermostat

An air conditioning system that never quite cools the house enough is often due to an incorrectly positioned thermostat. 

Your thermostat needs to be positioned in the warmest part of your house, this will ensure it cools the whole house to your desired temperature. If it’s located in the coolest part of the house the thermostat will think its job is done while the warmest parts have barely cooled.

Try the thermostat in different locations around your home to see the difference it makes to your living temperature.

Running Continuous

This one is the most costly as your air conditioning will be running non-stop. It is usually a result of a thermostat that doesn’t sit level or has too much dirt and debris inside it.

The result is that your thermostat will trigger a short cycling mode.

Alternatively, you may find that the anticipator inside the thermostat needs to be recalibrated. All you have to do is move the arm a notch or two towards the longer setting, this will lengthen the cooling cycle and prevent it from running continuously.

It is important to allow your air conditioning to run for at least one cycle after adjusting it; this will allow you to assess the effects of your adjustment.

Of course, not every problem can be solved. Sometimes it is as simple as the thermostat is old and is past it’s best before date. You may need to replace it in order for your air conditioning system to work properly. 

This is a job you can do yourself but it’s worth letting the professionals do it, they can check your entire system at the same time and ensure it is running properly.
