Amana Furnace Error Codes

For those who operate Amana furnace, there are tables on the page giving you all the necessary information about breakdowns and issues in its work. The tables contain Amana furnace error codes with their description and possible corrective actions.

Codes are described depending on their color and number of signals. For some modifications there are also associated messages given to improve the understanding of the problem character. Some codes are presented with different variations, for example Amana F1 error code has F1-1, F1-2, F1-A and many other variations. Each of them gives you different information which you can use to fix your Amana furnace.
