Hi
My master bedroom thermostat when set to 75F(for example) run only upto 68F.we called a technician and he diagnosed it.
He claims that( i also saw what he was doing) when thermostat was set to increase the heat, due to control board malfunction AC also starts to work. As a result at the same time Heat and Cool Air starts to flow.Technician wants 4777$ to change the board(timer control board on furnace) with 1 yr labor + 1 year parts warranty.
I was able to see the furnace starts to ignite gas flames and also AC starts to run and i can feel freon tube get chilled and the vent let out some cold air as well.
Technician already charged 80$ for diagnosis. I am trying to call someone else for 2nd opinion. Also want to know if i can just buy the contrtol board and fix myself.
Any advice please?
thanks
