    Keeprite ps90-dv pilot comes on burner doesn't fire
    When I turn the furnace on the pilot flame comes on and the burner does not fire.
    The pilot will cycle on and off a few times and then quit. This is an itermittent problem
    That is becoming more frequent. The unit is only 3 years old. Thanks for any help.

    Clean the flame sensor. See if that will allow the furnace to stay running.

    There are different styles on different units. Also be careful if you have to get around the ignitor since they can be easily damaged.
