Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Remove the wires from the fan assembly

Measurement:

Test 1:
Measure the resistance between the live and neutral terminals of the fan assembly.
Resistance should be approximately as per Table 1.
Test 2:
Measure between the live terminal of the fan assembly and a suitable earth.
Expect a resistance of 1 Mohm or greater.
Are the resistances measured as expected?
