Warning: stop telling folks diagnosis starts at the control board, that's backwards
In my 11 years fixing appliances around Bakersfield, the biggest thing I see other techs get wrong is jumping straight to the board when the real problem is almost always a bad connection, a dirty sensor, or a worn belt. Before you swap a $200 board, pull the schematic and check the cheap stuff first, and ask yourself the same thing I ask: what's the last time a control board was actually the culprit for you?
