    If it's brand new, have the installer look at it or contact the company.

    I agree with ma0641. However, one easy thing to do is add water to the drainage trap if easily accessible. On some high efficeincy furnaces, if the trap has no water in it, the draft inducer will push or pull air from the trap, causing the pressure switch not to close from lack of vacuum. Try this and see if it works. If you read completely through the install book, it may even mention this in there. Good luck.
