I had to change a bad ignitor on my coleman evcon furnace and now the ignitor is fine but no longer getting gas so is there a safety reset somewhere I need to reset or what? Everything worked great until I changed the ignitor, and no I'm getting no gas at all it's not the sensing probe not detecting flame

Look on the limit switch, if you have a reset it should be located there. Good luck and let us know how it goes. One user, Grady is really good with HVAC questions.

Check all the wiring. It is entirely possible when you changed the ignitor, you either bumped a wire loose or forgot to reconnect one. I've done it myself & I do this stuff for a living.
