Working air conditioning system has become a necessity for the Australian way of living. If your air conditioner isn’t turning on at all, then there is a good chance that the problem is electrical. Our AC is either not getting any power, or there is an issue connecting with the thermostat. Whether you have a split air conditioning unit or a Ducted air con Sydney system, it is likely to have one or more of the following problems preventing it from running.
1. Power Issues
This is one of the simplest causes of an air conditioning unit not running, yet so many people don’t consider it. It is recommended to check if the power has tripped or not. There may be a blown a fuse preventing the unit from getting power. This can often occur during the hot summer months when the AC unit has to work consistently to maintain cool temperatures.
Sometimes, AC units require so much power that they often require their own discrete breakers. It is recommended to check the breaker if it has flipped due to a surge.
2. Temperature Control Problems
Sometimes, it is the temperature control unit in the AC that may be having a problem. Usually, there is a sensor that controls the temperature of the unit by scanning the room’s temperature. A faulty connection between the electrical unit and the sensor can prevent cooling.
3. Non-Working Thermostat
An inoperative thermostat is the most common cause of an AC system not working in a home or office. When the thermostat is not working, it doesn’t matter whether your air conditioning system is working perfectly or not. A non-working thermostat will prevent the AC from ‘learning’ that the space is warm. This will prevent the unit from activating.
- If the thermostat uses batteries, check and replace them
- Check whether there is a broken circuit that is cutting off the thermostat’s power
- Check the settings to trigger the system to start by setting the thermostat to the minimum
If all this doesn’t work, get the help of a Commercial Air conditioning Repair company.
4. Clogged Drain Line
If the condensate drain line is clogged, the AC unit will not turn on as a safety measure. Air conditioners work by creating condensation, and the drain line is required for this function. You can check the line and try to unclog it. It is recommended to use a vacuum to clear it. If the AC unit features a condensate drain pump, chances are that it may be faulty and cause the safety switch to trip.
5. Turned-Off Air Conditioning Disconnects
Air Conditioning Disconnects, or ACDs, are breaker switches that go between the electrical power and the air conditioner. Their function is to turn off power to the unit if there is an emergency. They are also turned off during maintenance. If the ACDs are turned off, they will restrict the AC unit from getting any power.
So, your air conditioning may not be running due to these issues. If the problem is complicated and requires professional repair, you should seek the services of a Commercial Air conditioning Repair company.
