Hi All,
I replaced a blower motor and a WR control board on a Amana GUCA 13 year old furnace worked 1 day then no heat fan run all the time. Tripped out on roll out reset and furnace runs great for 5 starts and no sign of any rollout. Next day no heat same thing no signs of roll out with and without cover on. kind of weired worked ok until I had to replace fan and board. Any thoughts
