It's a Payne Forced Air Furnace with Cooling Unit the product no. 585hjw024040abae, model no. 585hj054040, like I was asking in my previous question. It doesn't have a circuit board it has a contacter,step down transformer,relay,capasitor,run capasitor,spark ignition module,gas valve. I changed the buss fuses and still nothing works.

Didn't see your previouse question. Can you please let me know what the problem is. I will try to help if I can.

Looking around,, I don`t know the question. Am I lost?

With all of the stuff you have changed, the first thing I would do is go back to square one and recheck everything to make sure all wires are in the right place and tight.

I do have one question, a lot of the roof top units only have 140 volts, but you said you were feeing your transformer with 120, I would look at the schematic.

letmetellu, are you going off info from a previous post. If so please let us know where this post is. In this post, I think they are just telling what they have. Not saying that they have already replaced all of these parts. I just don't know what the problem is with the unit(whats happening).

This is becoming a Payne. Need info.
