Upon my arrival in Paige I spoke with the customer on their concerns with the heating system not operating. I performed my diagnostics and found there is a short in the comfort control wiring that caused the electronic circuit board to fault. I spoke with the customer about their different options for repair and they approved to have the comfort control wiring replaced and also chose HE20E for the electronic circuit board repair. We will have to schedule out a return date to perform both repairs. Customer also signed the system up with our maintenance program but declined to sign their other system up at this time.
