Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Remove connector X2 from the PCB

Measurement:

Test 1:
Measure the resistance between pin 8 (pink) and pin 17 (brown).
Expect approximately 140 Ohms.
Test 2:
Measure the resistance between pin 7 (blue) and pin 18 (black).
Expect approximately 140 Ohms
Are the resistances as expected?
Note:
Each pin on the PCB connector is numbered.
