home and garden indoor environmental qualityHow do you check a thermistor with a multimeter?
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.
People also ask, should a thermistor have continuity?

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.
