How do you check a thermistor with a multimeter?

Last Updated: 8th March, 2020

Since thermistors are designed to betemperaturesensitive, testing them involves the applicationof heat.Set the multimeter to resistance mode. Hook up theterminalsof the multimeter to leads on thethermistor. It doesnot matter which lead goes to theterminals, as polarity is notimportant in thistest.

Consequently, how do you test a motor thermistor?

Testing a PTC thermistor follows allthesame steps as a NTC thermistor. First check, withanohmmeter, the thermistor without any heat applied. WithaPTC thermistor at room temperature or below,thethermistor should measure a very low resistance. Nowapplyheat, just like before, to thethermistor'sbody.

Beside above, what is the main function of a thermistor? Thermistors are thermally sensitiveresistorswhose prime function is to exhibit a large,predictable andprecise change in electrical resistance whensubjected to acorresponding change in bodytemperature.

People also ask, should a thermistor have continuity?

Customer Questions and Answers for ThermistorbyWhirlpool Got new part, it also does nothavecontinuity, hooked it in and ignitor does not goon, sono heat for dryer. Thermistors do nothavecontinuity, they show resistance. You should readaround10k Ohms at room temperature.

How do you test a temperature sensor?

Connect the black lead of the meter to the body ofthecold sensor and the red to the terminal. You should haveareading of approximately 2000 ohms. Check thewarmsensor in your engine. You should see a much lowerreadingon the digital meter.

How does a thermistor work?

A thermistor is an inexpensive andeasilyobtainable temperature sensitive resistor,thermistorworking principle is, it's resistance depends uponthetemperature. When temperature changes, the resistance ofthethermistor changes in a predictable way. The benefitsofusing a thermistor is accuracy and stability.
