2. Sensor Resistance Characteristic Table
• Tolerance of sensor resistance is ±5 %.
• Leave the sensor at measuring temperature for more than 3 minutes when measuring sensor resistance.
(necessary due to detecting speed)
• It is desirable to use digital tester as analogue tester has wider measuring temperature.
• Disassemble refrigerator sensor 1 and 2 from CON8 of main PWB assembly and measure it with digital tester.
• Disassemble freezer sensor from CON7 of main PWB assembly and measure it with digital tester.
