Hi everyone,
Hoping someone can assist me.
Found AC not working today - found that our furnace which is a Lennox 80 UHG3-75A-3 model circuit board is blown - heard since this is an older model that I have to replce the one board (the only board as newer ones now have multiple boards hence cheaper to replce) which is expensive. Any idea how to find this part and do replacement ourselves? Dire need to cut costs... :confused:
