Gas Pack

We have a Trane gas pack. It stopped putting out heat, but the fan was still blowing. I had gas in the tank. I opened the box up and the switch was on. That was the extent of my can do with a gas pack. I went online to try and fine a clue and found Just Answer. For nine bucks an online expert told me what the problem was based on my description and I think I just may, gods willing, be able to fix it myself.

...and no I didn't receive any compensation for this review so kiss my butt FTC.
