This sensor assembly monitors machine temperature and reports it to the controller so heating stays under control.

Replace it when the controller shows a sensor error, readings drift, and water temperature drifts away from setpoint, which affects drink quality. Disconnect power before service and check the wiring and connectors while the old part is out. Run several test cycles after install to confirm the controller reads the sensor correctly.

Fitment: National 623, 637.

Part number: VC3366.
