Report "I installed a 700A model on my furnace (does not have a bypass but has a fan built in). It is insallted on the supply side per the instructions. The "humidifier on" light is on when the funace is running. There is no water entering the humidifier and the fan does not seem to turn on. I wired the system per the wire diagram supplied. Power is on and water is on. I also have the knob cranked up to the highest setting. Can you please tell me why the fan won't turn on and why water is not entering the humidifer? Thank you for your help"
