Hi

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?


Thanks

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.
