Amana HVAC Error Codes

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.

Amana is not as well-known in Singapore as other aircon brands like Midea, Toshiba, or Panasonic. The primary reason is that Amana’s market focus is largely in North America, where it is popular for its durable and high-performance systems designed for larger homes and commercial spaces. However, a few Amana models have gained popularity in Singapore:

Amana ASX14 Series is one of the top-buys in Singapore due to its high durability. It operates with the environmentally friendly R410A refrigerant, making it an eco-friendly choice for residential use in Singapore.
Amana AVXC20 is a premium aircon model that is highly regarded among Singaporeans for its superior temperature control.
Amana ANX13 is one of the most sold Amana aircon in Singapore for smaller residential space.

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.

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.
