    Gas valve won't open

    Have a 58zav115, sn 5094a09437 gas valve doesn't open,. Inducer motor runs, igniter comes on,. But no gas?
    Checked continuity have no continuity across pressure sensor, but even when I bypass that,. No gas ?
    I have resistance across valve solenoid wiring, should I have?

    If you jumper the switch then it won't open the gas valve. The board checks to make sure the switch is open before the sequence can start.

    Most furnaces have a small window in the blower door through which you can see a (usually red) light. Count the number of blinks then open the blower door. On the inside of the blower door should be a key to the blink code.
