If you own an American Standard furnace, it is likely that you will have to troubleshoot it at some point in time. Fortunately, the American Standard furnace systems has an easy way that you can do just that.
These furnaces come equipped with what is known as a diagnostic light. This light can help you to determine if there is a problem with your furnace and what exactly that problem might be.
Near the bottom of the furnace unit, there is a small window with a red LED light. Depending on the status of the light, you might be able to locate the source of your problem.
If the furnace is working correctly, then the light will be continuously blinking red. There will be no long pauses between the blinks and the blinks will all be the same length.
When you are having problems with your American Standard furnace, the red blinking light might do some strange things. First of all, you might notice that your light seems to be sending you a code.
If you watch it long enough, you might notice that the light is doing three short blinks, pausing and then doing two long ones. If you see something like this at a time when your furnace is giving your problems, then the first thing that you should do is to write down the code.
The American Standard furnace red blinking light system is fairly easy to use once you know what you are looking for. Once you have learned to recognize the patterns in the light blinks, then you can write down what it is doing and find out what is wrong with the furnace.
Each time the light blinks, the furnace is sending you a code. Once you have written down how your light is blinking, then you can simply look in your furnace manual and find out what the code means.
In some cases, the code will tell you that you need to call a technician, but in others, you may find that the problem is simple to fix and you can do it on your own.
