Isolate Mains Power to appliance as per TOPs P4

Set Multimeter to Resistance

Remove connector LV2 from the PCB

Measure resistance across between pins 1 and 2 (blue) at the disconnected plug.
Is the resistance measured as expected?

Resistances vary with temperature and should conform approximately to the table below:
