Amana air conditioners are relatively expensive compared to other brands of the same line, which is why any issues with your unit will need immediate troubleshooting and repairs whenever possible.
In this article, we'll provide a full list of error codes for your Amana air conditioner and furnace. Keep in mind that any issues with electrical or internal components of your AC unit should be dealt with by a licensed technician at Luce Aircon. Refer to your manual for troubleshooting guides, or check out our article on Amana AC troubleshooting.
How to Display Amana Air Conditioner Error Code
The Amana line of air conditioners will not automatically display the error code on its LED screen. You will need to set the air conditioner to its diagnostic mode before identifying the error code. Here's how:
- Press and hold the UP/+ and DOWN/- buttons on your wireless remote thermostat, remote control, or control pad.
- Press the COOL button twice while holding the UP/+ and DOWN/- buttons.
The air conditioner should go into diagnostic mode, and display any error codes related to any issues detected by the unit. If the display reads two dashes (--), then it means the air conditioner has not detected any issue with your unit.
