just to update you:
Samsung service came today (Almost an hour late). Probed each sensor and connectors. Found the “room temperature sensor” to be defective. The ohm reading is off compared to whatever sensor he has. The fan is dead too.[br]
That is the diagnostic. The solution is to replace the entire cover/panel.[br]

For others who might have question about the service call/visit: [br]
the fees are ridiculous: trip charge, labor, and parts. It’s estimated over $350.
