RESISTANCE FLOW THERMISTOR AND HARNESS

Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4

Set Multimeter to Resistance

Disconnect connector X401 from the PCB

Measurement:

Measure the resistance between the
two red wires (pins 1 and 2) on X401.
Resistance should conform approximately to the table below:
