Hello David. You will need to test the hi-limit thermostat WP303395 and the flame sensor WP338906 and make sure they are good. They should read closed for continuity. Also, check the igniter WP33002789 and make sure it is getting hot enough to light the gas. If all of this is good, you will need to change the coils 279834.
