    I hope you did not clean the part that lites up. They are sensitive if it is a HSI system. They do not like fingers to touch them.

    A little about your furnace

    Check this one for a blocked vent tube and safeguard switch. It can be reset. Item 10 page 2. (push the button in to reset.

    This one has wiring diagrams and troubleshoot section.

    Now you are armed and dangerous. LOL

    I believe it is the HSI ignitor or no voltage from the board for the ignitor.
    Now get to work it has to be cold in there.

    Sure is just removet the ignitor plug from the board and see if 115 volts or there about is present at the terminals. Easy does it becareful not to touch your probes together. You can also test the ignitor with the OHM section of your meter.
