Hey, mister! Need a thermistor?In need of a thermistor Thermistor An electrical resistor with a relatively large negative temperature coefficient of resistance. Thermistors are useful for measuring temperature and gas flow or wind velocity. , NSN NSN National Stock Number NSN Nokia Siemens Networks NSN National Storytelling Network NSN NATO Stock Number NSN New Substances Notification (CEPA) NSN National Student Number (NZ) NSN Never Say Never 5905-01-399-4390, for your 18K environmental control unit (ECU ECU See: European Currency Unit ECU See European Currency Unit (ECU). )? Not sure? Can you control the heating and cooling by using the temperature select switch on the control box? If you answered, "not really," grab a multimeter An instrument for measuring electricity (volts, amps, ohms) that is widely used and available in numerous shapes and sizes. An analog multimeter displays results by moving a pointer across a printed scale. , set it to measure ohms, and make this check: Put one multimeter lead on pin 1 and the other on pin 2 of the J3 connector on the logic box. If you get a reading of about 8K-to 10K-ohms, verify the thermistor is functional by placing your fingers gently on the bulb. It's located in the return air duct adjacent to the fan shrouds for the vent motor. The reading should change because your skin temperature differs from the outside temperature. As you move your fingers off the bulb, the reading should return to the original setting. In SWA adv. 1. So. , you may need to cool your fingers with some ice before making this test.
