Today I arrived and met with Judith, I verified concern and the combustion air motor is seized causing a very loud noise. I attempted to contact manufacturer mortex and several local suppliers, no local suppliers stock this manufacturers parts and the suppliers have left voicemail with mortex. We are currently awaiting on a call back from the suppliers so we know how to proceed. With that being said I spoke to the customer about replacing furnace and she likes the idea of it and would like an estimate on possibly all electric system. Please call Judith to get them on the schedule with Daryl. Upon departure left the gas in off position and motor wire leads unplugged.
