What an Air Conditioner Error Code Means
An error code or flashing light pattern is the unit reporting a specific fault, from a sensor issue to low refrigerant to a communication error between the indoor and outdoor units. Codes are brand-specific, and we match them properly, ARC-certified under ARC #L160535 for the refrigerant side.
Common Causes of an Aircon Error Code
A sensor fault
Temperature or coil sensors drift or fail over time, and most brands report this as a specific code rather than simply stopping the unit outright.
A communication error between units
When the indoor and outdoor units cannot talk to each other properly, often from a wiring or connection fault, the system flags a communication error code.
Low refrigerant
Many brands detect abnormal pressure from a refrigerant leak and display a gas-related code well before the unit stops cooling altogether.
A drain or float switch fault
Units with a full drip tray or a faulty float switch often show a drain-related code to stop the system before it overflows.
Ageing units in older Highland Park homes
Estate-era systems installed through the 1980s to 2000s building years are more likely to throw a code as components like sensors and boards age.
Can I Fix an Error Code Myself, and Is It Urgent?
A code is rarely an immediate emergency, so a power reset is a reasonable first step, but a code that returns points to a real fault that needs proper diagnosis rather than repeated resetting.
- You can note the exact code or flashing pattern and try switching the unit off at the wall for a few minutes
- Matching the code to the correct brand, whether Daikin, Mitsubishi, Fujitsu or Actron Air, needs the right fault reference
- Refrigerant, sensor wiring and internal boards are ARC-licensed or electrical work, not a DIY job
- A code that keeps returning after a reset is a same-day job, not something to keep resetting indefinitely

What To Check Right Now
Before calling, a few checks help us diagnose the fault faster on arrival:
- Write down the exact error code or count the flashing light pattern precisely.
- Note the brand and model of your unit, whether Daikin, Mitsubishi, Fujitsu or Actron Air.
- Try turning the unit off at the wall for a few minutes and switching it back on.
- Check whether the code appears immediately or only after the unit has been running a while.
- Call an ARC-certified technician (Lic #83326, ARC #L160535) if the code returns.
When To Call an Aircon Technician for an Error Code in Highland Park
- The same code returns after a power reset
- The unit stops cooling or heating alongside the flashing code
- You cannot match the flashing pattern to a code in the manual
- The code relates to refrigerant, drainage or a communication fault
- The unit is an older system nearing the end of its typical lifespan
Any of these on a Highland Park unit needs a proper fault diagnosis rather than another power cycle. We respond same-day where availability allows, with clear pricing before we start. See our air conditioning repairs.

Why This Is Common in Highland Park Homes
Highland Park's estate housing stock, built out from the 1980s through the 2000s, means plenty of units nearing the age where sensors, boards and refrigerant charge start throwing codes rather than failing outright.

Common questions
Air Conditioner Error Codes FAQs
Here are the questions Highland Park homeowners ask most about error codes and flashing lights on their air conditioner, covering causes, DIY checks and cost.
What does an error code on my air conditioner mean?
Error codes are brand-specific and usually point to a sensor fault, a communication error, low refrigerant, or a drain or float switch issue inside the unit.
Why does my air conditioner keep flashing a light pattern?
A flashing light pattern is the unit's way of reporting a fault code without a display screen, and it needs matching to the brand's manual or a technician to read properly.
Can I fix an air conditioner error code myself?
You can note the code and try a power reset, but sensor, refrigerant and PCB faults behind most codes are ARC-licensed or electrical work for a technician.
Do I need a technician to clear an air conditioner error code?
Yes, if the code returns after a power reset, the underlying fault needs a proper diagnosis rather than repeated resetting of the unit.
How much does it cost to fix an air conditioner error code?
It depends on the fault the code points to, so we give clear pricing before we start once we have diagnosed it, with every option explained on site.
Are error codes brand-specific for Daikin, Mitsubishi, Fujitsu and Actron units in Highland Park?
Yes, each brand uses its own code system, so we match the code to the correct brand's fault list before diagnosing your Highland Park unit.
