| [title] Test thermistor circuit | |
| [* black] Measure the resistance between the two white wires as shown in [document|38965|this document]. | |
| [* black] Gently put the probes into the connector holes that correspond to the white wires. Alternatively, you can use sharp insulation piercing probes on the white wires. | |
| [* black] Note the resistance and the temperature of the thermistor and compare it to [document|38968|this chart]. | |
| [* black] If the measurement is neither open (OL) nor shorted (less than 1Ω), measure the temperature and consult the table of resistance vs. temperature in the chart above. If it isn't in spec, go to the next step. | |
| + | [* icon_note] The resistance of the thermistor should be about 11kΩ at room temperature. |
| [* black] If the measurement shows a short circuit (near zero resistance) or an open (infinite resistance) go to the next step. |
