Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove connector X2 from the PCB
Measurement:
Measure resistance across the orange (pin 4) and black (pin 10) on X2.
RESISTANCE WARM START SENSOR AND HARNESS
Resistances vary with temperature and should conform approximately to the table below:
| Temperature Range (°C) | Resistance Range |
|---|---|
| 0°C to 10°C | 20.0kΩ - 34.0kΩ |
| 10°C to 20°C | 13.0kΩ - 20.0kΩ |
| 20°C to 30°C | 8.0kΩ - 13.0kΩ |
| 30°C to 40°C | 5.3kΩ - 8.0kΩ |
| 40°C to 50°C | 3.5kΩ - 5.3kΩ |
| 50°C to 60°C | 2.4kΩ - 3.5kΩ |
| 60°C to 70°C | 1.7kΩ - 2.4kΩ |
| 70°C to 80°C | 1.2kΩ - 1.7kΩ |
| 80°C to 90°C | 900Ω - 1.2kΩ |
| 90°C to 100°C | 700Ω - 900Ω |
