RESISTANCE SAFETY THERMOSTAT AND HARNESS

Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4

Set Multimeter to Resistance

Remove connector CN4 from the PCB

Measurement:

Measure the resistance between pin 1 (white)
and pin 2 (white) on connector CN4.
Expected resistance short circuit (zero resistance).

Note.
On some PCB's the connector will be labelled as CN12 not CN4 and its orientation will differ, however the test points and expected results remain the same.
