Even if you have the best inverter AC in Pakistan, error codes are part and parcel of the convenience they provide. Most of us have seen these errors on our master controllers once or twice and have legitimately worried sick about whether the air conditioner is completely done with or if there are ways you can yet save it. All worries aside, most of the error codes that you see on your air conditioner are very easy to fix. Most of them might just require a quick troubleshooting guide while others may need you to take them a little more seriously.
For this very purpose, we have put together this article through which we are going to tell you what all the error codes mean as well as reasons why your air conditioner might be acting up.
There are several reasons why your air conditioner might be showing up errors, but most of the general reasons are:
Your unit is out of gas.
Due to wear and tear (for old units)
Sudden weather events
Issues with switches and plugs
Tripped circuit breaker
Reduced local power supply
Delayed compressor starting or
Delayed fan starting upon turning on
If one of these are the reasons why your air conditioner might not be working properly, one way is to reset your air conditioner. Resetting does not mean turning on/off. It means to erase the existing memory on the air conditioner board to initiate a fresh restart. To figure out where your reset button is on the outdoor unit, you can try calling the customer service. This might save you a service trip, but we do recommend that you isolate the problem first before trying anything out.
There is a wide range of errors that you might see on your air conditioner, but we are only going to review some of the more common ones. Knowing what is wrong may help you in getting to the core of the problem and seeking help early. This would also be advantageous information for when you go buy an air conditioner online or from a dealer.
