Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Remove electrical connector from gas valve

Measurement:

Test 1:
Measure the resistance between pins 1 and 4 of the gas valve.
Expected resistance approximately 7.3 kOhms.
Test 2:
Measure the resistance between pins 1 and 2 on the gas valve.
Expect a resistance of 1MOhm or greater.
(O.L is acceptable because it is greater than 1MOhm)
Are the resistances measured as expected?
