spent a good 2hrs taking apart da furnace and cleaning da biotch da best i could. i couldnt find any blockage.
was hoping the heat exchanger was clogged, but mine is a old 80% so no grill or nothing.
cleaned each of the blower's fins. was kinda dirty
but not sure if datz going to fix da over heating and lock out. everything else works fine, hauz is warm too.
