How to Check a Thermistor in an RV Refrigerator | It Still ...

A thermistor is a resistance-based temperature sensor and testing its accuracy is the first step toward determining whether the problem lies here, or elsewhere. Thermistor failure is a common issue in RV refrigerators and generally causes the temperature to fall too low. Fortunately, replacement thermistors are relatively inexpensive and repair manuals are available online.

Using a Thermistor | Thermistor | Adafruit Learning System

2012-07-29· A thermistor is a thermal resistor - a resistor that changes its resistance with temperature. Technically, all resistors are thermistors - their resistance changes slightly with temperature - but the change is usually very very small and difficult to measure. Thermistors are made so that the resistance changes drastically with temperature so that it can be 100 ohms or more of change per degree ...

How to Test a Thermistor - Learning about Electronics

PTC thermistors are thermistors whose resistance increases when the temperature it is exposed to increases. So if heat is applied to a PTC thermistor, its resistance increases accordingly. Being that thermistors are components which vary their resistance according to the amount of heat applied, we can exploit this property to test it. All we need to test a thermistor is an ohmmeter or a ...
