arcoaire condensation

My combustion blower keeps filling up with water. I take it out and drain all water from it and replace it. Runs fine for an hour or so and fills up with water again. I have checked trap and drain hoses and they are clear of obstructions. What could be the problem?

I'm assuming you have a 90% gas furnace?
Check that he hose coming from the bottom of the heat exchanger cover doesn't go uphill before down to the trap. This will stop it from draining & trip out the pressure proving switch.
