Testing Thermister on Refrigerator Fins
- Unplug Thermister from circuit board & measure resistance across the 2 wires according to the chart below.
- The temperature in the refrigerator should tell you the resistance reading.
- Measure Thermister wire to Ground and it should read “Infinity”
| Temp in Refrigerator | Resistance | |||
| 28 Degrees | = | 10.7K | ||
| 30 Degrees | = | 9.9K | ||
| 32 Degrees | = | 9.2K | ||
| 34 Degrees | = | 8.6K | ||
| 36 Degrees | = | 8.1K | ||
| 38 Degrees | = | 7.6K | ||
| 40 Degrees | = | 7.1K | ||
| 42 Degrees | = | 6.9K | ||
| 46 Degrees | = | 6.2K | ||
| 50 Degrees | = | 5.6K |
Testing 110 VAC Burner Element
- Remove Element wires from J7 & J8.
- Put Voltmeter probes across J7 & J8 & have someone push Refrigerator “Eyebrow” Temperature Control from 1 thru 5 & you should read 110VAC when it sends a signal to turn on 110VAC element.
- If that is working then you need to test the 110VAC element.
- Connect the 2 wires you removed from J7 & J8 to a 2 prong male 110VAC plug that you can pick up at any hardware store.
- Plug it into 110VAC outlet.
- This will bypass the circuit board & tell you if the element is working or not.
- If the element is working it will start to cool the refrigerator.
