If your Frigidaire air conditioner is displaying an A2 error code, this could be a system error, or it could indicate a problem with one of the components.
Error codes are intended to make it easier for you to find and fix a problem with your air conditioner (AC) before it becomes too much of an inconvenience.
If your Frigidaire air conditioner is displaying an A2 error code, you should first reset the unit, and then check whether it has frozen or if there is an issue with the unit’s remote controller or control panel.
Error codes on air conditioners
An air conditioner can be quite a convenient appliance during the hotter, summer months, but when your air conditioner suddenly stops working, this can result in a lot of frustration and confusion.
Air conditioner manufacturers have tried to lessen the confusion and frustration that customers face when their air conditioners do not work the way that they are supposed to.
They have done this by programming the air conditioners to display a specific error code when one of the internal sensors picks up that there is an issue with one of the components in the AC.
Frigidaire air conditioner error code A2
These error codes are supposed to assist homeowners and professionals to notice problems with the operation of their air conditioners, but also to help them diagnose and fix these problems much quicker.
However, since these error codes are manufacturer-specific, it means that Frigidaire error codes may differ from the codes used by other air conditioner brands and they may even vary from one model to the next within the Frigidaire brand of air conditioners.
This means that although an error code, like an A2 error code, seems like it would have a clear cause and solution, you may still need to try various troubleshooting options to get the error cleared from your air conditioner and to get the air conditioner working normally again.
If your Frigidaire air conditioner is displaying an error code of any kind, including the A2 error code, your first step should always be to reset the unit.
If resetting your Frigidaire air conditioner clears the error code, you can continue to use your air conditioner as normal without having to investigate or inspect further.
If the A2 error is not cleared after you reset the air conditioner, this indicates that there is really something wrong with the functioning of the machine and you can start investigating. Some of the reasons why your Frigidaire air conditioner may be displaying an A2 error code include:
- The antifreeze protection mode has been activated
- The remote controller or control board is not working as it should
How to reset your Frigidaire air conditioner when it is displaying an error code
Air conditioners have many internal sensors and temperature sensors that monitor the functioning of the machine and that warn you if there is something wrong with one of the unit’s components.
Unfortunately, just like with any other electrical appliance, it can sometimes happen that the system in your Frigidaire air conditioner has gotten confused or overwhelmed and that the error code is being displayed in error.
This is why you should first reset your Frigidaire air conditioner when it displays the A2 error code, before you investigate further, to ensure that there is really an issue worth investigating.
To do this, you simply need to turn the Frigidaire air conditioner off, wait a few seconds, and then turn it back on again.
If this did not clear the A2 error code from the display, then there is really an issue with one of the components in your air conditioner, which is affecting its functionality and that you should investigate further.
If the A2 error code indicates the antifreeze protection mode
It is common for ductless mini-split Frigidaire models, like the FFHP362SQ2, to display the A2 error code when the antifreeze protection mode has been activated on your unit.
This error signifies that your air conditioner has gotten too cold and may begin to freeze if it continues to operate in this way. There are numerous things that could be causing this, including:
- Low refrigerant levels
- Poor airflow
- Lack of power to the fan motor
- Dirty air filters or coils
If the A2 error code indicates remote controller or control board error
An A2 error code on Frigidaire room air conditioner models like the FGRC1044T1, indicates that there is an issue with the remote controller or the control board of your AC.
In this case, you can replace the batteries on your remote controller or replace it with a universal controller first. If this does not work, you need to contact a professional to inspect your control board.
