I called my Friend who built the Deck for me. He said there r 3 wires coming from outside and going into the Motherboard. He was saying that if you have only one thermostate to control and may be one for fan then he was questioning to himself why there r 3 wires entering the motherboard.
He then removed one wire ( they were just red and blank) then fixed back , But i didnt had any heat for the night and the fan was blowing the cold/normal air then in the morning i went to see as it was cold and open the box and found one wire hanging which i fixed as i knew where it was before.
So now the Furnace also fires up and the fan too and the good news is that now the fan shuts off after the furnace shuts off as it was before. So for now the things r back to normal and good. BUT NOW I AM WORRIED WHY THIS PROBLEM HAPPENED and how i can prevent this from happening in future as now i will be always worried that the thing just got resolved on its own without doing anything so i might face this problem again.
I have provided the details for the board and see if it would be advisable to have it as a spared or atleast to know how i can get it and how long it will take and what is the price.
Kindly give ur expert advice.
