White streak on furnace

[hotdog]

Second season with my goodman condensateing furnace,duel fuel. I was in basement and noticed a white streak down the side of furnace 1/4 inch wide coming from bottom of coil. It was dry and didn't make it to floor. I tried to remove with MR.Green cleaner but as soom as it dried came right back. Used a little WD40 and it disappeared.Do I have hole in drain pan already?

Vapor (suction) line maybe sweating and dripping, if it was a hole it would be all over the floor too.

Impossible to say for sure with just the info posted, but I doubt it. I would think that if the pan had a hole in it you would have had much more than just a streak down the side of the furnace. If it comes back, post a picture of it.

later,
