RETURN SENSOR RESISTANCE THROUGH HARNESS

Isolate Mains Power to appliance as per TOPs P4

Set Multimeter to Resistance

Gain access to PCB
Disconnect plug X6 from PCB (6 way plug 2nd from right)

Measure resistance across the red (pin 4) and black (pin 3) wires.

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

Note: Clicking on the resistance table will switch between table and graph view.
