Hi everyone. I have a Halstead Hero 40. The problem I am having is the the burner fails to work when the heating comes on, sometimes it does come on but then half way through the evening it fails again. I can hear the fan running in the back ground. I generally reset it but it doesnt last long until it fails again?? Any ideas why this is happening? What do i need to do? I'll be greatful for any replies. Thanks Zippie.
