| [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. |
| - | [* black] If the measurement shows a short circuit (near zero resistance) go to the next step |
| - | [* black] If the measurement shows open (infinite resistance), check the resistance at the thermistor itself. You can either pierce the insulation or cut the thermistor off and then measure its resistance. If the thermistor tests ok replace the refrigerator. Otherwise replace the thermistor. |
| + | [* 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 and replace the thermistor |
| + | [* black] If the measurement shows a short circuit (near zero resistance) or an open (infinite resistance) go to the next step. |
