Set Appliance State:
Set Multimeter to Resistance 
Isolate Mains Power to appliance as per TOPs P4
Measurement:
Measure the resistance between connections 3 (White wire) and 4 (Grey wire) and then between connections 4 (Grey wire) and 8 (Purple wire) and then between connections 8 (Purple wire) and 3 (White wire) on connector CON2 on the Fan Driver PCB. A reading of approximately 5.5 ohms should be obtained for each measurement (specified resistance of approx 2.5 ohms + meter probe of approx 3 ohms).
