Tip & How-To about Heating & Cooling
If your system is newer than 10-years old, you may have a diagnostic center built-in to your system. This may come in handy when trying to diagnose why the system is not working. Usually there is a LED light on the board. After a few unsuccessful attempts to start, the center logs an error code and blinks it on that LED. Unfortunately some furnaces erase the code as soon as you remove the panel with the door safety switch. Many manufacturers have installed a small viewing port that you can look and see the error code without having to remove the panel. Once you get the error code you may need to either look in the manual or on the "glued-on" wiring diagram to see what the error code refers to. Often it is a starting point and may not give you a precise diagnostic result. If you can't find the codes for your model, you will have to do an internet search for a service manual or error codes for the unit. Always check and clean your air filter, check for blockage of all vent pipes as well as drain hoses and condensate pumps. Sometimes it is the simple things that cause the most headaches.
