Where is the drain pan on Payne Model PF1M? I A/C is leaking in my house. It is not coming from the drain line.

, the drain lines are connected to the drain pan

I repaired a leak with epoxy right where the 3/4 mail thread pvc screws into pan. I put it back together and it ran and then shut down. I reset the breakers and still nothing. Does my repair interfere with the vacuum of the unit?

At the bottom of the unit
