The Bard only heats the master bedroom fortunately as it is about -1F
here right now... and snowing. Anyway, yesterday the furnace did not
come on in the morning as it is programmed to do. I checked the
filter. Clean.

If I turn the circuit breaker off then on again the furnace starts
right up. Oddly, the breaker is not tripping.

And the Trane furnace (which heats the rest of the house) right next
to the Bard is working perfectly.

Ideas? Suggestions?
