Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now.

Check the front cover switch and make sure it is working then check and see if you are getting 24 volts to the valve when the ignitor is glowing, if you are not then the board is bad or the wiring from the valve to the board is loose or broken. Now if you do have 24 volts to the valve the valve is bad, you have a gas supply issue or you have blocked orifices on the burner and need to clean them. You just need to check those things to see what the issue is.
