RESISTANCE THERMISTOR

Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4

Set Multimeter to Resistance

Disconnect thermistor plug from PCB

Measurement:

Measure the resistance across the thermistor plug.
The resistance varies with temperature and should conform approximately to the table below.
