Customer Question

Good Evening, I am reading a reply to the same problem I am having with the blinking light, no pattern for the attic fan. It appears to be working fine on both the A/C and the furnace functions. I can bypass the alarm and the trouble light by re-aligning the switches. This is a Coleman Model G1NA036S17LA.

Hello,

Can you send me a few photo's of the switches that you are re-aligning, and a photo of the units wiring diagram taken up close, well focused and well lit?

Use the paper clip icon at the right end of the tool bar above for that.

We can go from there.

Hello again,

Thanks for the picture.

Look that over for an explanation of how it works.

So far it sounds like there is a problem with the blend air controller or that the blower shown in the diagram on the roof, that is the blend air intake, is bad.

Look that over, we can go from there.
