How do I get the pilot to light on my GLUA90-E5A unit? It seems to have stopped working.

I have a conquest 90. model GLUA90-E5A. The pilot has stopped lighting. Both fans work, it just won't light.

This could be due to a range of issues, but is probably a safety feature of the furnace preventing it from lighting. If you look at your owner manual you'll probably see that there is an electronic ignition listed on the schematic of the furnace, which is how the pilot is lit. Therefore, it could be that this is malfunctioning or it could mean that there is uneven airflow through the furnace such as due to a very dirty filter or some other issue that is tripping a safety feature.

To find out more, there should be a set of lights or an LED display that you can see through a window on the furnace or by opening the front panel. If they are blinking they indicate an error code. Hopefully there is a description of the codes pasted to the furnace, which should explain how to read the codes and what they mean (I can't find a list online). You may find this in the owner manual as well.

You can also learn more about troubleshooting these furnaces here: http://www.ehow.com/how_7905099_troubleshooting-conquest-furnace.html.

Of course, if you are not familiar with working on a furnace you should call in a certified HVAC tech. You can find one in your area here: http://www.furnacecompare.com/perl/find_contractors.pl.

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.  To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
