Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove high voltage connector to fan
Measurement:
Measure the resistance (continuity) across the fan high voltage harness leads.
Connections are;
X2 connector pins 2, 3 & 4 to corresponding connection on the fan connector.
Expected resistance is continuity (zero resistance).
Note.
Ensure a good connection is made or misdiagnosis will occur, connector & pin numbers are printed on the PCB.
