Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove connector X20 from the PCB
Remove connector to thermal fuse
Remove connector to thermal fuse
Measurement:
Measure for resistance across each wire of the thermal fuse harness, pins 10 & 6 (brown leads) of connector X20 to thermal fuse connector.
Expect continuity / zero resistance on each wire.
Also visually inspect the harness for good general condition.
Are the resistances as expected and is the harness in good condition?
Note.
Ensure a good connection is made or misdiagnosis will occur.
