[title] Test thermistor circuit | |
[* black] Measure the resistance between the two white wires as shown in [document|38965|this document]. | |
- | [* black] Use |
+ | [* black] Use a [product|IF145-035|multimeter|new_window=true] set to the ohms (Ω) setting. |
[* 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] |
- | |
+ | [* black] Measure the resistance of the thermistor. |
+ | [* black] If the measurement is neither open (OL) nor shorted (less than 1Ω), measure the temperature in the fresh food compartment. Compare these figures to [document|38968|this chart]. 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. |
