Thermistors are of two types, NTC (negative temperature coefficient) and PTC (positive temperature coefficient types). As their name indicates the resistance of an NTC thermistor will decrease with temperature and the resistance of a PTC thermistor will increase with temperature. Both PTC as well as NTC thermistors can be roughly checked by using an analogue

A properly functioning negative temperature coefficient thermistor will show a smooth and steady decrease in the multimeter resistance reading. Look for signs of a faulty thermistor. A steady reading that does not change, a reading of zero or a reading of infinity are all indications that the thermistor needs to be replaced.

NTC thermistors are the most commonly used (especially the 10KΩ NTC thermistor) and along with an addition series resistor, R S can be used as part of a simple potential divider circuit. Thus changes to its resistance due to changes in temperature, produces a temperature-related output voltage.

• ### How to Set Up a 5V Relay on the Arduino - Circuit …

One of the most useful things you can do with an Arduino is control higher voltage (120-240V) devices like fans, lights, heaters, and other household appliances. Since the Arduino operates at 5V it can’t control these higher voltage devices directly, but you can use a 5V relay to switch the 120-240V current and use the Arduino to control the relay.

• ### How to replace a refrigerator thermistor | Repair …

This DIY repair guide gives step-by step instructions for how to replace a refrigerator thermistor. The thermistor senses temperature changes in the refrigerator and sends the control board a signal about the temperature change. If the thermistor fails, the refrigerator won't stay at the temperature you set, resulting in items either freezing or spoiling because it's too cold or too warm.

• ### Doing The Thermistor Shuffle – RV Refrigeration …

By moving the thermistor from one part of the cooling fins to another you are effectively readjusting the resistance and “tricking” the control board. For instance, if your refrigerator is running around the 42 degree mark consistently you can move the thermistor to a location that gets cold more slowly so that the food cabinet actually drops to 38 before the control board shuts of the ...

• ### Thermistor - Wikipedia

Een thermistor is een elektrische weerstand (component) waarvan de elektrische weerstand afhankelijk is van de temperatuur.Het woord thermistor is een samenvoeging van de Engelse woorden thermal en resistor.. Thermistoren worden voornamelijk gebruikt als temperatuursensoren, beperken van aanloopstromen, zelfherstelde overbelastingsbeveiliging, en in zelfregulerende verwarmingselementen.

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 ...
