I have an old Austroflamm Integra pellet insert. Lately , it has been shutting itself down. It starts up fine, but soon after the circ fan comes on, it shuts itself off. The circuit board was rebuilt last year, and has worked fine last winter, and up to now. Any suggestions where to begin looking for the problem? Thanks.
