FIREPLACE DIAGNOSTIC: The unit is not working off the remote due to the remote’ a batteries failing. On top of the failed batteries I found that the “on, off, tstat†switch was in the off position. The switch needs to remain in the “tstat†setting for the remote to be engaged to the system. She is also going to sign the unit up today on a service club membership as well. I will drop the diagnostic fee to $60 being that she’s signing and we will contact her for the first visit.
