Boiler fires for heating or hot water from cold. During heating, about 30 minutes after it has started, boiler starts giving intermitten fault where fan runs burner fires and shuts down a second or two later (not sufficient to time out for FF lockout).
Monitoring voltage on APS brown wire- No voltage when boiler idle or stopped due to intermittent fault. Restarting boiler by switching off then, on at the timer, Fan runs, see voltage on brown for about a second or two. Then no voltage and burner goes out. Fan does not spin when boiler in fault state.
Any suggestions guys?
