If your aircon won’t start or acts erratically, the control system could be to blame. This system handles power, temperature, and fan speed. Learn the signs of control failure, what causes it, and how to fix or prevent control problems in your aircon.
What Is Electrical Control Failure?
First of all, your air conditioner relies on several electrical parts to operate. These include the thermostat, circuit board, and various switches and relays.
When any of these components malfunction, your aircon may stop working completely or start acting strangely.
So, how do you know if your aircon has an electrical issue?
Here are some key signs to look out for:
The Unit Won’t Turn On
Firstly, if the power is working in your house but your aircon won’t start, the problem might lie in the internal wiring or the control board.
Unusual On-Off Cycling
Next, if your aircon turns on and off too frequently, the electrical controls could be failing to read signals properly.
Unresponsive Remote or Wall Control
In some cases, you might press buttons on your remote or wall unit and nothing happens.
This could mean the signals aren’t reaching the aircon’s internal control system.
Burning Smell or Sparks
If you ever smell burning plastic or see sparks coming from your unit — turn it off immediately.
This is a clear sign of an electrical issue and a potential fire hazard.
How to Fix It
While some electrical issues can be simple to fix, others should only be handled by professionals.
Here’s what you can do:
1. Check the Power Supply
Before anything else, make sure your aircon is plugged in and the power outlet is working.
Also, check your circuit breaker — a tripped switch could be the culprit.
2. Replace the Batteries in Your Remote
Sometimes, a weak remote battery can cause communication issues.
Try new batteries and test the remote again.
3. Reset the Aircon Unit
In many cases, a simple reset can help. Turn off the unit for a few minutes, then turn it back on to see if the issue clears.
4. Call a Professional Technician
However, if none of the above works, it’s best to get help from a qualified aircon technician.
They can safely check internal wiring, control boards, relays, and replace any damaged parts.
Preventing Electrical Control Failures
Fortunately, many electrical issues can be prevented with regular servicing.
Get your aircon checked at least twice a year
Avoid overuse or frequent on-off switching
Make sure your home’s electrical wiring is in good condition
