Furnace is condensating?
 
During the night, my furnance shuts off (the piolot has a hard time lighting again and the house gets cold. I also notice there's water that is in a tube connecting the fan and the (thromoeter) Why is there water backing up in my furnance?

good picture andy... you say you have water in orange tube...pull tube off inducer and clean out the little port....also go to other end of tube at pressure switch make sure tube is not cloged.. thats a inner city product...tempstar,heil.. right

It's an older ICP product.

Haven't seen a collector box for sometime now. If you are getting water in the orange tube and you shouldn't because this is an 80% furnace. I would check the flue for a restriction.

port is connected to the fan, right.. how do i clean this?

Just remove the orange hose and blow through the hose. Look at the ports where the hose connected and look for a blockage.

The bigger picture is that you said there is water in the hose and this is NOT a condensating furnace.

that may explain the water in tube ..but sill should operate because its closing pressure switch.....how much water in tube,,,,just a few drops?

If I had a dollar for every bird that falls to it's death down a flue pipe. I'd have about $20. Check the flue to make sure it still has it's cap in place. You may have a weak inducer motor.

The only way to know is to measure the pressure of the inducer. You will need a manometer to check the pressure. Inch of Water Column (In wc)

Nothing last night/ 3 a.m. this morning... I dont know if you got the message about the coils underneath the furnance for the air conditioning... could the hot air mix with the (cool) coils causing condensation backing up in the furnance?
