Dometic 630515 Thermistor
A thermistor is a thermal resistor, that has a fluctuating resistance that is contingent on the temperature. The system reads the temperature in a few critical areas to make a decision on what needs to be done. They tell the circuit board when the temperature has been reached.
Some clues your thermister should need replacing
- Primary blower could refuse in the attempt to engage full speed
- The system may not operate because of any inaccurate thermistor
