The air conduit in the attic has fallen a few inches from the other conduit to the big box because the tape used to link to the big box came off. After looking into it, the conduit needs to be lifted and attached with metal straps to the roofs. Now the Nest thermostat messages show that there has been interruptions of the heat production maybe because of a faulty "flame sensor". I am not sure the fact that I'm loosing heat from that opening would trigger a flamme sensor issue. Only my master bedroom thermostat (downstairs) does not heat the room/bathroom at all in the past 3 weeks.
Does it make sense to anyone, this issue?
