Set Appliance State:

Gas Off
Set Multimeter to Resistance Set meter to measure resistance
Isolate Mains Power to appliance as per TOPs P4
Set the Thermistor-stat to maximum

Measurement:

Measure the resistance across connection 8 (blue lead) and connection 9 (brown lead) the main terminal block located on the back of the electrical door assembly.
Resistance should be approximately 13kOhms.
Note: The resistances will change depending on the Thermistor-stat setting. Resistance should be between 10kOhms (minimum setting) to 13kOhms (maximum setting). The resistance should be approximately 27kOhms for the Summer Airflow setting.
