Will this fix ignitor not shutting off issue on Pit Boss 340 ?

looking for control board for camp chef pellet bbq model #SE24

Does this fit the pb 700r1 - rancher?

Will this work on the PB500LXW1 model? My smoker still works, but the display is blank so I don't know what the temperature is with the probes.
