Possible Causes

Disconnected thermistor, Broken thermistor lead, Open thermistor element, Damaged harness between thermistor and PCB

Safety: Disconnect power before servicing.

Access thermistor: Remove the front or rear panel (model dependent) to reach the exhaust/drum thermistor.
Check connection: Ensure the thermistor plug is fully seated on the terminals and not loose.
Inspect wiring: Look for broken or pulled-out wires at the thermistor and along the harness.
Test continuity: Measure resistance across the thermistor. An infinite reading indicates an open circuit. Replace the Samsung thermistor if open.
