Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Disconnect spade connectors from modulating solenoid
Disconnect plug from safety solenoids

Measurement:

Test 1:
Measure the resistance across the modulating
solenoid coil terminals.
Resistance should be approximately 125 Ohms.
Test 2:
Measure the resistance across the safety solenoid terminals.
Resistance should be approximately 890 Ohms.
