suddently, my gas furnace truned out, and, i tried several times based on following procedure, seems like does not work for me, any help? many thanks

---------------
- Turn off the gas at the main valve at your utility box
- Wait five to ten minutes for gas fumes to waft away
- Get a long match—yes, a fireplace match, not a standard match
- Set the gas valve on your furnace to “pilot”
- Press the red button as you hold the match to the pilot valve
- Keep pressing the red button for 30-60 seconds so the pilot can heat the thermocouple. Release the button and see if the pilot remains lit
- If pilot goes out, wait five to ten minutes and repeat the process
- Once the pilot stays lit, turn the main gas valve back on
- If the pilot light continues to go out, call a technician, who may need to adjust or replace your thermocouple or adjust your pilot
