Customer Question
I have a Lennox...

I have a Lennox G40UH-48B-090-11. It has no red or green light and the drip pan was full

Contractor's Assistant: I'll do all I can to help. How long have you been dealing with this?

I cleaned the drip pan and tried to blow out the Drain line.

Contractor's Assistant: How long has this been going on? And how severe is the problem?

I just saw it when my thermstat went out today. There seems to be no red or green light

Contractor's Assistant: Do you plan on doing the work yourself?

If i can i would like to

Contractor's Assistant: Anything else we should know to help you best?

Thats about it

Look at the white plastic condensate drain line for a tee with a tiny float inside with two wires attached, if you find that, its probably stuck in the up position, clean it out... let me know how that goes.
